Sony MDRZX310APB.CE7

The standout stat here is the 91st percentile comfort rating, making these some of the most wearable headphones in our database. That comfort comes at a cost, with sound quality sitting at a mediocre 65th percentile and call quality tanking at 22.1 out of 100. At a normal budget price, they're a solid buy for comfort-obsessed casual listeners, but the current $9,847 listing is a hard pass.

These are driven by 30mm neodymium drivers with a 24-ohm impedance and 98dB sensitivity, so your phone or laptop will drive them without breaking a sweat. The sound signature is what we'd call inoffensive. With a 65th percentile sound ranking, it's solid for podcasts and YouTube, but music lovers will notice a lack of detail and a fairly narrow soundstage. The bass doesn't dig as deep as you'd hope, and the highs can get a little splashy at higher volumes. For gaming, the 39.3 score reflects the lack of spatial awareness you'd get from a proper gaming headset.

The mic is the real letdown. A 54th percentile ranking puts it just below average, and our calls score of 22.1 confirms it. Your voice will come through, but it'll sound thin and compressed, picking up a fair bit of background noise. Build quality is another area where corners were clearly cut, landing in the 37th percentile. The all-plastic construction feels creaky, though the folding design is a nice touch for portability. There's no active noise cancellation to speak of, so the 33rd percentile ANC score is generous, it's just passive isolation from the on-ear pads.

Stacked against the Sennheiser MOMENTUM 4 or the Bose QuietComfort, the Sony MDRZX310AP isn't even playing the same sport. Those competitors offer best-in-class ANC, wireless connectivity, and sound quality that would embarrass the Sony. The Beyerdynamic Aventho and Bowers & Wilkins Px7 S3 are in a different universe for build and audio fidelity. The only real comparison here is the Skullcandy Aviator, another budget-conscious option. Even then, the Skullcandy likely offers a more fun, bass-forward sound signature. The Sony's sole victory is in comfort, where it outperforms many headphones that cost ten to twenty times as much. It's a one-trick pony, but for the right person, it's a very good trick.

Let's address the elephant in the room. The listed price of $9,847 is a complete anomaly and you should absolutely not pay that. These are budget headphones that typically sell for a fraction of that. At their normal price, the value proposition hinges entirely on comfort. You're getting a 91st percentile comfort rating for pocket change, which is a rare find. The trade-off is middling sound and a terrible mic. If your priority is a pair of headphones you can wear for hours without fatigue and you don't care about pristine audio, the value is there. For anything else, even a slight bump in budget gets you a massive upgrade in sound and build.

The Sony MDRZX310AP is a budget wired headphone that punches way above its weight in comfort, landing in the 91st percentile. That's genuinely impressive for a pair of cans that fold up and weigh next to nothing. But the moment you look at the sound score, sitting at a middle-of-the-pack 65th percentile, you realize this is a comfort-first, performance-second kind of deal. The 30mm drivers deliver a frequency range of 10Hz to 24kHz, which is fine for casual listening, but don't expect any audiophile magic here.

Where things get weird is the price. We're showing a current listing of $9,847, which is either a data glitch or someone's idea of a joke. At its real-world sub-$30 street price, this is a cheap, cheerful wired headset. The built-in mic and 3.5mm jack make it a simple plug-and-play option for calls and basic gaming, though the 22.1 out of 100 score for calls tells you the mic is a weak spot. If you need a lightweight, comfortable headphone for a kid or as a backup pair, the comfort alone makes a case for it, assuming you ignore that bizarre price tag.

Anyone who values sound quality or build should skip these without a second thought. The 65th percentile sound ranking means music will sound flat and uninspiring, and the 37th percentile build quality suggests they won't survive much abuse. If you take a lot of calls, the 22.1 calls score is a dealbreaker. And if you're looking at that $9,847 price tag, run. Even at their normal budget price, spending just a little more gets you a massive leap in audio performance and durability from competitors.

The Sony MDRZX310AP is a comfort king trapped in a budget body. If you need a pair of wired headphones that you can genuinely forget you're wearing, the 91st percentile comfort score is the real deal. But you have to accept significant compromises in sound, mic, and build quality to get there. This is a perfect pair for a non-critical listener who prioritizes all-day wearability, or as a cheap backup set. Just make sure you're paying the real-world price and not the bizarre $9,847 figure we're seeing. For anyone who cares even a little about how their music sounds, look elsewhere.
