Sony has been in the portable audio game for a while now and we’ve come to expect some pretty big things from it. We were a little let down when the MDR-1Rs turned out to be fairly average cans without much to make them stand above the pack. But that was then and this is now.
The latest in the MDR lineup, the Sony MDR-1ABT (MSRP: $399.99), feature NFC and Bluetooth 4.0 letting you pair and listen to them with or without cumbersome cables. Combine that with a comfortable, modern design and a built-in touch sensor on the right earcup and you’ve got a compelling piece of hardware.
But, when it comes to wireless headphones there’s undoubtedly going to be a loss in audio quality when you transmit over Bluetooth. And you’re shelling out hundreds of dollars for a pair of headphones, it’s likely you care about how your music sounds. Sony does have a few tricks up its sleeves though, and we took the 1ABTs to the lab to see if they live up to the $400 price tag.
Bulky yet plush, it’s a winning combination
In order for Sony to justify its steep asking price, Sony had to bring its A-game to the look and feel of the MDR-1ABTs. It can fit all of the fancy technology it wants into its headphones, but if Sony doesn’t make them look as well as they sound, it’s going to have a tough time finding consumers to buy them. Luckily, this isn’t Sony’s first rodeo, and the 1ABTs have a look and feel that matches their price.
The earcups are absolutely massive. Now, I have fairly large ears—it is what it is—but the 1ABTs completely encase them in thick, soft padding. There’s even enough space inside the earcups that my ears aren’t pressed uncomfortably against the driver housing.
With plenty of padding on the headband and earcups, the 1ABTs are the perfect storm of comfort.
That soft padding isn’t only on the earcups either. The band that rests on top of your head also has a generous helping of padding. No matter what part of the headphones touch your head there’s going to be at least a half inch of padding between you and them.
On paper, everything about the 1ABTs should spell out exceptional comfort. However, there is a fair amount of pressure exerted by the earcups that makes them press a touch too tightly against my head. Plus, the large cup size, while a perk in terms of ear comfort, means that force is almost entirely localized to my jaw. It’s still pretty easy to spend a good amount of time jamming to tunes, but you’re going to want to take a break at least every hour or so to recover from the pressure.
Of course, the real star of the show is the wireless capabilities of the 1ABTs. For starters, Sony also included NFC tech into the headphones, allowing you to use a compatible device to connect to them sans cables. Once paired, audio is streamed via Bluetooth 4.0—with the help of Sony’s LDAC technology—for a cable-free listening experience.
The right earcup has a single button to power on the wireless and the input port for the audio cable.
However—and this is the case for all wireless headphones—streaming audio wirelessly means you’ll inevitably suffer a loss in quality. While this is mitigated by LDAC, you’ll need to have it in both the output and the input to experience the full benefits. That means using other Sony branded products like its stereo systems or their new Walkman to listen to your music. Otherwise it won’t sound as full or detailed as it was intended to. But, when I listened through my non-Sony phone and MacBook Air computer, I was able to discern a higher quality using wireless then when I used the Momentum Wireless headphones. Just don’t count on that always being the case.
You may not think you’ll be able to notice the loss in quality when you go wireless, but if you do a comparison test, you almost definitely will. Still, the benefits of ditching that pesky cable might outweigh the loss in quality for some people. We’d just recommend trying it out for yourself before making a commitment.
The new tech doesn’t stop there. A removable audio cable makes it rather difficult to have an in-line controller for music and phone control. Instead, Sony opted to include another premium feature: touch controls on the right earcup. Swiping up or down controls volume, left and right for skipping and rewinding tracks, and a double tap to answer phone calls or play/pause your music. The touch sensor is a great addition and hardly impacts battery life at all.
In the time I spent testing the 1ABTs, I only experienced a few minor hiccups in the controls and that had more to do with my finger placement than the sensor not working. Just like a smartphone, once you get a taste of the touch controls you’ll wonder why all wireless headphones don’t include it.
Following the trend of other manufacturers with similar headphones, Sony kept the included accessories to a minimum with the 1ABTs. The headphones come in a large box, but once you get into the packaging all you’ll find is the 1ABTs, a removable 4-foot cable with 3.5mm, a micro–USB cable to charge the battery, and a carrying pouch. That’s it.
Other than an audio and charging cable, the only accessory you’ll get is a carrying case.
High-quality sound that defies wireless expectations
When it comes to premium headphones, there’s an expectation for high-quality sound that justifies breaking open your piggy bank. As audiophiles are quick to say, though, wireless headphones are known for dropping quality by virtue of being transmitted via Bluetooth. They might have to eat those words though, as Sony is implementing new technology in 2015 to deliver high-quality, lossless audio whether your headphones are wired or not.
When it comes to its wired performance, the 1ABTs have a frequency response that looks very similar to an equal-loudness contour. That means that the entire spectrum is balanced in a way that makes the whole spectrum able to be heard equally as well. Bass sounds get a slight bump that really emphasizes the deep, bumping sounds without losing the higher frequency sounds in the midrange. There is a slight drop in the upper mids that gets a little too low, but overall your music is going to sound detailed and balanced, no matter what genre it is.
There’s going to be a slight drop in audio quality if you take advantage of the 1ABTs ability to go wireless. When using Bluetooth 4.0, sounds are a little less full and detailed than it would otherwise. This is somewhat mitigated by Sony’s LDAC technology, which is a wireless audio codec that allows up to three times more data to be transmitted than standard Bluetooth.
Paired with LDAC is DSEE HX, which attempts to upscale your audio to make up for the details that are normally lost. While you’ll still experience a slight drop in quality when you go wireless, you probably won’t even notice a difference unless you do a comparison test and have very sensitive hearing.
There’s a small amount of fuzzy, crackling sounds that can be found in the bass notes. While it was technically audible, the bass frequencies are the most difficult for human ears to pick up distortion so your mileage may vary depending on how sensitive your hearing is.
As for the 1ABTs ability to block ambient sound, they perform on par with to other over-ear headphones. They have a slight advantage because of the thick padding that completely encases your ears, but when it comes to the deep bass sounds—the ones from a bus or train engine you’ll encounter on a commute—they’ll hardly be blocked at all. Also, unlike some of its competition, Sony chose not to include active noise cancellation in the headphones, presumably to save on battery life.
Even the midrange sounds—which you’ll find plenty of in your normal daily routine—are only partially lowered, sticking fairly close to 75% of its normal volume. As you move into the mid and high-range frequencies, ambient sound drops off precipitously. High-midrange tones are about half as loud as they’d normally be, while high frequencies are dropped to just 1/8th their level.
