The wireless headphone market has been shaken up so much recently that it’s hard to know where to begin when a new entry appears on the stage and announces itself as the next big thing.

Fortunately this latest Bluetooth offering from Sony is targeting a very specific market segment best referred to as “premium noise cancelation”, and the company seems pretty confident that with the MDR-1000X headphones ($400), it has got a hit on its hands.

Sony is claiming “industry-leading noise cancelation” with these luxury cans, which use ostensibly the same drivers as last year’s highly regarded MDR-1A headset made for listening to Hi-Res Audio, as supported by the company’s audiophilic Walkman range, not to mention its line of wireless home speakers and in-car audio systems.

Can it improve upon the finely honed features of Parrot’s Zik 3.0, Bose’s QuietComfort 35, and Sennheiser’s PXC 550 Wireless noise-canceling headphones? Let’s take a look.

Design

The Sony MDR-1000X’s come in a box design and hard carry case that will seem suspiciously familiar to Bose QC35 owners, but that’s where the similarities pretty much end. I received a beige pair (also available in black) that came with a nice thick matching 1.5 meter cable sporting a gold-plated mini jack, along with a black micro-USB charging lead and an airline adapter.

The swivel-folding earcups and pivots are made of a robust, creak-free plastic, with champagne-colored rims and squishy earpads covered in smooth synthetic leather that’s pretty convincing to the touch.

The polished steel headband packs some decent padding between the adjustable slats, and Sony has decided to let the design speak for itself by keeping the branding relatively understated. The only other distinctive mark on the outside of the cups are two small grilles where the noise-canceling microphones live. Altogether the headset weighs 275 grams, so slightly lighter than the QC35’s (309g).

The left earcup contains an NFC chip for pairing with compatible devices and a micro-USB port for charging, while the right earcup has a touch-sensitive back that responds to taps and swipes to control music playback, skip tracks, change volume, and invoke Siri. Like most modern headphone gesture pads, it can also be used to take and end calls.

Around the rim of the right earcup are three physical buttons and an input jack. Unfortunately these controls aren’t particularly textured or distinctive, so expect some fiddling when you’re wearing the headphones before you get used to where they sit in relation to each other (although voice prompts helpfully accompany each press). The Ambient button lets you choose between different external sound filtering modes which we’ll cover below, the NC button lets you turn noise canceling on and off independently, while the power button can be pressed quickly for a battery level update and also activates the pairing sequence with a long press. All of the buttons have inset LEDs to indicate status.

Performance and Features

It’s worth stating right off the bat that Sony has taken noise cancelation to a new level with these headphones. This seems to have been achieved through a sustained period of self-reflection and extensive acoustics research in light of earlier shortcomings, combined with an exhaustive exercise in technological oneupmanship. In other words, Sony has pulled out all the stops in an attempt to beat Bose at its own game.

To begin with, Sony has chosen a headset design with a firmer grip than its NC rivals so that the earcups alone do a better job of isolating you from the outside world. There’s a slight trade-off here – Sony has used thicker urethane foam earpads than those found on Bose and Sennheiser’s NC cans to improve passive reduction, and they don’t feel quite as plush against your head as a result. It’s not a deal breaker by any means – they still feel lovely and squishy, and never bothered me after several hours of listening, but a few minutes back with the QC35’s was all it took to confirm they do lack the latter’s sumptuous cushiness.

Second of all, Sony’s patented Sense Engine boasts a “personal NC Optimizer”, a fancy-sounding piece of tech that’s supposed to determine your individual characteristics and wearing style to optimize the audio output just for you. Basically, Sony had the bright idea to build a microphone within each ear cup, which means the headset can sample ambient noise from both inside and out, effectively canceling out a wider range of sounds with corresponding inverted frequencies.

Hold down the NC button, and the headphone speakers emit a series of tones that bounce back and forth between the mics to analyze the shape of your head, work out whether you have big hair, wear glasses, and so on. It’s a unique innovation from Sony in the NC space – and it works, too. The only minor drawback for some wearers will be the ever-so-slightly more noticeable hiss when no music is playing. I found it pretty relaxing, kind of like distant lapping ocean waves. Your mileage may vary.

Otherwise, the NC easily stood up to scrutiny in a range of environments, including a busy bus and a crowded shopping mall. It didn’t detract from calls either, and effectively piped in my own voice as part of the conversation. The filtering is adaptive too, and corrected for changes in ambient levels as I moved around. These are also the first pair of noise cancelers I’ve worn that completely blot out my heavy-handed keyboard tapping and reduce my house phone in the same room to a barely audible, faraway whisper.

You don’t even need to take off the cans to realize just how effective the technology is, thanks to another feature unique to the Sense Engine called “Quick Attention”. Cupping your fingers over the touchpad instantly turns the volume down and lets in the outside world, allowing you to engage someone in conversation. Bring your hand back down and the music is re-instated to its prior volume. It’s genuinely useful for situations in which you’d usually be apt to take off the headphones – when a fight attendant offers you refreshments, for example.

The MDR-1000X’s Ambient button performs two further NC sound tricks. One is called “Voice mode” and lets in the range of sound frequencies the human voice normally occupies. This is also meant to let you hear in on important announcements – when you’re waiting to be called to a boarding gate, say – while still allowing you to enjoy your music in relative quiet.

I found the feature a bit overly enthusiastic, sometimes failing to filter out other ambient sounds like the rustle of bags and suchlike which then became exaggerated and annoying. The “Normal” ambient mode on the other hand worked very well, and let me stay mindful of traffic sounds as I walked the street without entirely extinguishing that insulated cocoon feeling that good NC cans do so well.

Sony’s headphones certainly have a stronger Bluetooth connection than the competition – the MDR’s didn’t drop out once in areas where rival Bluetooth headsets I’ve tested regularly faltered. The link was retained around harder corners and over bigger distances – the MDR-1000X’s even passed the ‘microwave test’ and didn’t get all glitchy as I hovered around the kitchen while my dinner was being nuked.

Wireless audio connections have their limits of course, but Sony has also included a neat sound prioritization feature in the MDR-1000X that I haven’t seen in other cans. By default the headphones automatically select the highest quality Bluetooth protocol available, but hold down both power and NC buttons for a couple of seconds and you can switch them to “Priority on stable connection” mode, which falls back to the less-demanding SBC codec. Bear in mind I’ve no idea how well it works because I never had to use it.

On the subject of wireless codecs, this headset supports them all: AAC (iPhone), aptX (Mac/Android), SBC (everything), and LDAC. That last one is a Sony special which apparently transmits up to three times more data than conventional Bluetooth for superior sound, but it only works with Sony devices, such as the company’s Xperia smartphones and Walkman digital audio players. There’s some proper science behind it and I have it on good authority (an audiophile friend) that it delivers on its promise, but I didn’t have any other Sony hardware to test it with.

To be honest though, it didn’t bother me. The MDR-1000X’s sound brilliant over bog-standard Bluetooth anyway, and certainly outperform the QC35’s thanks to a wider, more expansive soundstage. The mid-range is wonderfully balanced and the highs sparkle, while a good, chunky bass serves as a warm foundation. They sound even better when the cable is used – so long as the headphones are on. Whether this is all down to Sony’s DSEE HX processing (which allegedly recreates higher frequency signals lost in low-quality compressed music files) or simply better tuned drivers, I can’t say. Whatever the reason, the MDR-1000X’s sound fantastic, especially for NC cans.

A few other points bear noting. Unlike the QC35’s and PXC 550’s, Sony’s headphones don’t seem to be able to pair with more than one device at the same time. I had to manually disconnect my iPhone to reconnect with my Mac, and vice versa, despite the fact that the cans had no trouble auto-pairing with the last known device when turned on. Also, the 1000X’s live up to their 20 hour battery life, but they take 4 hours to fully charge – twice as long as Bose – and the battery is similarly integrated, so it has to go back to Sony if/when it comes to replacing.

Bottom Line

Sony has pulled a fast one on its rivals here. For a company whose last serious attempt at noise canceling was the h.ear on Wireless NC headphones, the MDR-X1000’s are a huge step up in performance. Not only do they look smart and block out distraction, they also pack a ton of technology (not to mention compatibility), keep a strong connection, and deliver a beautiful sound.

It’s a sure sign that the premium NC market is maturing, and that translates to better consumer choice. For those who favor comfort, always-on NC and listening simplicity, Bose still wins. If a bigger sound and the ability to switch between multiple audio sources are your top considerations, Sennheiser’s PXC 550 cans are a great alternative. But if superior noise canceling and audio quality are more important to you than cushiness and dynamic pairing, then these new MDR-1000X headphones from Sony have your back.

Pros

  • Unrivaled noise canceling
  • Exceptional sound for wireless
  • Multiple audio codec support
  • Solid design and touch controls

Cons

  • Comfy, but not Bose-comfy
