HTC Sensation XE with Beats Audio review

We had some hands-on time with HTC’s new European Android flagship a short time back, however it wasn’t nearly enough to respond to all our questions on how the 4.3-inch, 1.5GHz dual-core XE compares to the unique 1.2GHz Sensation, or whether the implementation of Beats Audio was anything greater than a cunning scheme cooked up between the manufacturer’s marketeers and Dr. Dre’s agent. Now, though, this phone have been our closest companion for long enough to show its true colors. They’re red, primarily, but there is a whole rainbow of detail right after the break.

Hardware

In lots of respects this isn’t a total review, because we’ve avoided covering the similar ground we already trod extensively in our review of the Sensation . Instead, we’ve focused only on those areas where there were significant changes, or where the passage of time has altered a selected spec’s standing with respect to the ever-eager competition.

Especially, we spent numerous time looking into Beats Audio — far an excessive amount of time, perhaps, if you’ve already convinced yourself that this Dre hookup is nothing but a gimmick. But we felt that since HTC has invested untold dollars in Beats on the way to differentiate itself from the contest, and because it plans to bring the this technology to many more devices inside the US and around the globe, then we must attempt to get a hold of something definitive and — if in any respect possible — scientific. By all means, if you are just fascinated by this phone’s musical prowess then skip all the way down to the Software section, but for now we’ll begin with the secret hardware features.

Like the original Sensation, the XE is definitely-built and delightful to behold. Its tapered edges and smooth wraparound aluminum case conspire to make it feel thinner than the 11.4mm statistic might suggest. Obviously, the XE differs in its coloring and once we first heard in regards to the red accents we were worried they would look cheesy, like a Qosimo gaming laptop or something, but our fears were misplaced. The coloring of the navigation button back-lights, the speaker grill and the hoop round the camera lens all helped to raise this phone above the apparent black and silver hordes. The speaker grill and front-facing camera both have glinting chrome borders which cause them to look out of the ordinary. Add within the bold red headphones with the Beats logo at the back of every bud and it’s an all-round good look — unless you like your gadgets to be more discreet.

In the event you grip the telephone hard you’ll feel and listen to slight creaks from the plastic-aluminum hybrid construction, but it is lower than what you get on purely plastic phones. We should always also mention that regardless of how we held the device, we did not encounter any of the so-called “death grip” issues that folks complained about with the primary Sensation.

Perhaps the sole nits we’d pick — and they are much smaller than your average nits — are the tendency of the border between glass and aluminum across the panel to gather dirt which cannot easily be cleaned, plus the strange slant of the facility button. We must always probably disregard this latter flaw, because the device in our hands-on did not have it and it is able to simply be a factory error or as a result of the transit damage. Nevertheless, if wonky power buttons become a difficulty with this phone, then remember: you heard it here first.

Processor

We did not have an original Sensation to match against the XE side by side, but we did have an EVO 3D to throw into the combination, which has a 1.2GHz dual-core Qualcomm MSM8660 processor that’s very like the Sensation’s MSM8260. The comparison isn’t perfect, since the EVO 3D has 1GB of RAM rather then 768MB, but it’s nevertheless sufficient for a demonstration of what 1.5GHz delivers with regards to real-world advantage — which seems to be not a lot. The EVO 3D actually booted much quicker than the XE, taking just eight seconds from ‘Off’ to snapping an image at the camera. Meanwhile the XE took 11 seconds to do the identical thing — possibly for the reason that extra Beats Audio logo animation takes a number of extra seconds at boot up.

Our Quadrant Standard benchmark scores clustered around 2080, which was significantly greater than the EVO 3D (1800) but only slightly greater than the unique Sensation (2000). Linpack gave us 43MFLOPS for the XE, versus 41 for the EVO 3D and 46 for the feeling — so nothing worth shouting about there either. Meanwhile, the Sun Spider javascript benchmark for browser speed timed the XE at approximately 3,300ms, which was much healthier than the strangely slow 6320ms time from the EVO 3D, but not a whole lot quicker than what you’d get from the one-core iPhone 4. Forgetting benchmarks for a minute, the truth remains that webpage rendering at the XE was impeccable.

Our impression was that anything the XE could do, the EVO 3D could with reference to to boot, so the additional 300MHz doesn’t count for far in any respect in practice. We won’t help but notice that the chip within the XE is similar to that during the unique Sensation and has merely been overclocked — something savvy Sensation owners are perfectly in a position to doing themselves.

Battery Life

HTC bumped the battery as much as 1750mAh within the XE rather than the unique 1520mAh, ostensibly to allow you to take heed to more tunes but in addition perhaps also to make amends for the 300MHz bump to the unique Sensation’s clock speed. The lower portion of the case heats up once you put the processor under any serious load and you’ll just imagine how those two cores should be gulping down energy. After a 14-hour day of heavy use, including tonn of music, a couple of photos and a bit video, the battery fell to 8 percent by the point we got on a train home. It subsequently fell to a few percent after paying attention to about half-hour of music after which finally died after taking four final night-time photographs. In other words, there is no forgiving fuel tank here; when the battery says it’s nearly dead, it’s. However, a dead ringer for with the unique Sensation, the telephone is frugal with power while it’s idle and on a less busy, more normal day we’d still find around 30-40 percent of the battery remaining when plugged the telephone in to charge.

In our regular battery test, looping a typical def video with low-to-mid connectivity and push settings, the telephone died somewhere between five and 6 hours, that’s just below average for a giant screen device. For the sake of reference, the three.7-inch single-core BlackBerry Torch 9850 lasted 20 percent longer during this test — which merely shows that the feeling XE pays for its specs in battery life.

Camera

The camera hardware within the XE is the same to that during the unique Sensation, so inspect that review for an entire appraisal. All we actually ought to add is that the slight increase in clockspeed with the XE might translate right into a minor improvement within the time it takes to load up the camera app and begin capturing video or stills, but it’s nothing particularly noticeable — in fact, the unique Sensation was no slouch on this regard first of all.

Then again, something has changed significantly for the reason that XE’s predecessor, and that is time. Because the months have progressed and new handsets have come to market, we’ve become less forgiving of XE camera’s flaws — particularly with video. The automobile-exposure isn’t particularly smart, and it adjusts too quickly when filming video, with ugly results in comparison with the camera inside the HTC Titan and Sensation XL — that have much better camera units. Moreover, as you’ll hear within the sample video above, the sound recording is terrible: its default sensitivity of the mic is much too high, leading to clipped audio whenever the man holding the camera speaks, or when there is a gust of wind or the other sharp noise.

7

Still images be afflicted by the truth that you cannot change the compression settings, which suggests the output from the eight megapixel sensor is normally ruinously over-compressed to as low as 600KB. HTC’s panorama mode, which we’ve enjoyed at the Titan and XL, is absent here, too. Altogether, the camera counts firmly against the XE and feels far more outdated than the display panel.

Software

Beats Audio

HTC’s marketing department has gone to town with Beats Audio. For the record, here’s among the language they’ve used to explain it:

“Beats by Dr Dre and HTC will interact to reengineer how sound is delivered in order that the buyer feels the music the manner that the artist intended.

“In relation to doing music justice, you’re way just before the group with… Beats Audio™”

“The tailor-made headset is specially engineered to deliver extraordinary sound. Finally, hear what you have been missing.”

Mainly, this hyperbole condenses right down to two separate claims: that the XE makes music sound more just like the original artist intended, and that it also involves tailoring the music output to the matched Beats headphones.

8

Beyond these two claims, there’s little or no within the way of factual information from HTC about what exactly Beats Audio is. When we’ve interviewed HTC reps in this point, the conversation has generally ended up being about “sound profiles,” which we take to intend EQ settings — or the style certain frequencies are lifted or depressed so as change the style music sounds. This fits with the impressions we had in our initial hands-on with the XE: that Beats Audio is only an EQ setting that involves life whenever you attach Beats-accredited headphones as a way to lift the bass and a few of the higher frequencies and hence deliver a more lively experience with certain genres of music.

We all know that the Beats Audio EQ can sound great with the perfect form of music, but we’d like something more objective than that. So, with EQs as our start line, we decided to check out HTC’s claims about Beats Audio with help from the friendly chaps at AMS Acoustics in North London. Attributable to their input, we have now a ton of objective information regarding exactly what Beats Audio does. Indulge us together with your patience and we’ll do our greatest to clarify.

Round One

We began by testing the XE with the packaged YourBeats in-ears, that are re-branded iBeats with the addition of HTC’s in-line controls. As you will see within the video above, our test involved playing pink noise at the XE, with BA first enabled after which disabled, and recording the sound using a mic specially modified for the analyzing this kind of earphone. This yielded two different power spectra, that are presented as simple tables showing the amplitude (in dB) of every frequency (in MHz) of the pink noise. Subtracting the primary spectra (BA off) from the second one (BA on) revealed the Beats Audio EQ, — i.e. how, exactly, the XE modifies the sound when you activate Beats Audio. For corroboration, we also ran a different test signal through the XE and YourBeats in order to get a “frequency response curve,” which is basically just a higher-res power spectrum depicted as a line graph. (Look in the gallery above for more tables and graphs at a higher res.)

The first thing our tests revealed was that the Sensation XE and packaged headphones form a bass-heavy system, even before you activate Beats Audio. Looking at the raw data with BA disabled, we see that the lowest frequencies still have the highest amplitude, while the higher frequencies get steadily quieter. This EQ is the equivalent of old-school “bass boost” and we’ve listened to enough music with BA off to know it sounds just about as boring.

9

Our next step, of course, was to enable Beats Audio, and this changed the picture entirely. Suddenly, there’s a massive boost to most of the treble frequencies as well as the bass, which prevents the treble from just trailing off so dismally. Looking at the Beats Mode EQ column above, we can describe the EQ as S-shaped: it has a hump at the lowest frequencies, then a valley in the middle, and a second hump at the top. This is significant because, for many types of music, an S-shaped EQ is greatly preferable to one which simply emphasises the bass. Subjectively, activating Beats Audio when listening to music does exactly what we’d expect from a good S-shaped EQ: it gives the music more presence by emphasising the bass and vocals, while depressing the less interesting mid-tones — but only when we’re listening to an appropriate genre of music such as hip-hop or house. When listening to orchestral music, activating Beats Audio does nothing good.

In addition to the treble boost, most of the other frequencies are also amplified to a greater or lesser extent, delivering an overall jump in loudness that screams “Beats Audio ON!” in the language of pure decibels. This is supported by the frequency response curve below: the BA-enabled curve follows the BA-disabled curve very tightly, but is significantly higher (i.e., louder) all the way along — with the extra boost at the bass, upper mid-range, and highest trebles that we’ve already observed.

0

At this point, we can debunk one of HTC’s more ostentatious claims about Beats Audio, which is that it somehow “reengineers” music to make it sound “the way the artist intended.” For this to be true, the Beats Audio EQ would need to flatten the system’s output, to make music sound more faithful to the source recording — just as studio monitors do. But Beats Audio does no such thing. We’d suggest that this makes music sound the way Dr. Dre (or his engineers) intended: with a certain S-shaped EQ that suits his kind of music. In fact, when we suggested this to an HTC rep during our hands-on video, he didn’t contradict us. Round one therefore goes to the skeptics — albeit, with the caveat that Dre’s EQ can actually sound really good when you try it with the right type of music.

But we have another question to answer before we call it a match: HTC’s second claim about Beats Audio being tailored to the packaged Beats headphone. Does the same Beats Audio EQ get activated regardless of which headphone is plugged in? If the answer is “yes,” then the consumer is simply being duped into thinking a dumb EQ is more than it is. If the answer is “no,” then the marketing spiel has some justification.

Round Two

Our approach in this round was to run the pink noise test with three other sets of headphones: Senn CX300 in-ears, Senn HD598 over-ears and a pair of Beats Studio active over-ears. We threw in the Beats Studios to mix things up a bit — they’re part of the Beats range but they’re not officially supported by the XE. Currently, the only supported headphones are YourBeats and Beats Solos, with the latter soon to be sold with the new limited edition 2 Sensation XL 2 .

We should also clarify at this point that our XE allowed us to activate Beats Audio with whatever headphones we liked. However, it only explicitly acknowledged the YourBeats headphones, which triggered a popup message on the XE’s screen when we plugged them in. We’re not sure this is how HTC intended the software to behave — in fact, we’ve been told that Beats Audio should not be available with the third-party headphones. But this is how the review device worked for us — and a good thing too, because it allowed us to learn a lot more about Beats Audio.

So, starting with Beat Audio disabled, we noticed that the same excessive bass was apparent with the CX300 in-ears. However, when we moved on to the more expensive and more balanced over-ear headphones, the bass boost was matched by a similar boost to the lower trebles. This suggests that XE has been designed with a relatively common S-shaped sound profile already, even without Beats Audio enabled, but this treble amplification is largely lost with the in-ear Senn CX300, just as it was with the packaged YourBeats.

What happened when we activated Beats Audio in these tests? Well, this is where it got interesting. With the Senn CX300, Beats Audio further boosted the bass as well as some mid-range frequencies, but it totally failed to remedy the lack of treble. In other words, the EQ it applied was clearly different to that with the YourBeats, and the end result was nothing like Dr Dre’s S-curve we discovered in the last round. The same can be said of both the over-ear headphones we tried: they generally displayed the same pattern, with a bass and mid-range boost, but the end result was nothing like with the YourBeats. This is illustrated in the graph below, which compares the Beats Audio EQ with the YourBeats, versus the average Beats Audio EQ with the other headphones. The shapes are totally different, and the key difference is the treble.

6

This tallies with what an HTC rep told us about the way Beats Audio works: the XE has multiple sound profiles stored within it. It has separate and specific profiles for the YourBeats and Solos, plus a third ‘generic’ Beats Audio profile for other headphones, which are inherently less tailored. We can only assume that the YourBeats EQ above represents the tailored sound profile, while the other headphones were all given the generic BA profile, which looks significantly different. It’s entirely possible that the Beats engineers were aware that the YourBeats headphones have trouble delivering the treble end of the S-curve and so deliberately adjusted the tailored EQ to compensate. This means we must notch up a point for HTC: Beats Audio does appear to tailor the XE’s output to suit compatible headphones and deliver a predictable and good-sounding S-shaped power spectrum.

This leaves us at a 1-1 draw between HTC and the skeptics. The skeptics won a point when the Beats Audio power spectrum proved to be S-shaped and hence have nothing to do with “what the artist intended.” HTC drew level when it turned out that Beats Audio only delivers this particular S-shaped spectrum with the compatible headphones. So can we call it quits? Nope, we need a final round.

The decider

If we take a step back from all these charts and consider the fundamental value of what Beats Audio achieves, then we have to come down squarely on the side of the skeptics. No matter how much effort we put into testing this thing, the fact remains that these ‘sound profiles’ are just EQ settings. You can achieve precisely the same effect using PowerAMP, which costs $5 and allows you create your own EQs. PowerAMP can tailor and save your EQs to suit current headphones and even to the track you’re listening to, if you want to get the sound just right. The app can also apply the EQ to lossless music, which cannot be played by the XE’s stock player and therefore cannot be listened to with Beats Audio enabled. Listening to the Black Eyed Peas in Apple Lossless format, with our own PowerAMP EQ and the YourBeats headphones, provided a great experience — and it was achieved while Beats Audio was switched off and irrelevant.

8

Sure, you might think lossless is overkill, and you might not have the patience or the time required to experiment with your own EQs. But we think that anyone who loves listening to music would surely appreciate having full control, and if HTC was true to its marketing they would have made this possible. If, in addition to Dre’s EQ and headphones, Beats Audio also meant we had an amazing stock player, with tons of EQ customization and a better user interface than PowerAMP, we’d be happy. If HTC went whole hog and threw in a high-end DAC to improve the overall quality of the XE’s output, we’d be over the moon. There’s still plenty of time for HTC to make improvements like that, but until then we can only conclude that Beats Audio is mostly a gimmick.

Wrap-up

The Sensation XE is a great phone, but it is no more or less great than the original Sensation. Sure, it has some spec bumps, but these are minor and cancelled out by our concerns about the display and camera, which haven’t aged well over the last five months.

The Beats Audio software isn’t complete marketing vapor, but it’s still inherently gimmicky and adds nothing within the XE’s favor: you could achieve a better result on the original Sensation simply by downloading a third-party music player that lets you play with the EQ settings yourself.

The only thing which might sway us to by the feeling XE over its predecessor is the packaged YourBeats headphones, coupled with the red styling at the phone. But for us to opt for the XE, it’d must by priced similarly to the unique Sensation, such that we are not paying much extra for these headphones. They’re only good if they seem to be a bargain — otherwise we’d choose to take matters into our own hands and spend $80 to $100 on some Etymotics, which might be even better.
