Audio-Technica ATH-TWX9

The ATH-TWX9 nails sound quality and fit, with clear vocals, deep bass, and a genuinely customizable wearing experience. But the battery life is weak, real-world ANC disappoints, and a recurring left earbud charging issue makes it hard to recommend unconditionally. Pricing varies a lot, with EUR listings running from EUR 303 to EUR 375, so deal-hunting pays off. Buy it if you prioritize audio above all else, skip it if you need reliable everyday performance.

Sound is where this thing earns its keep. The high-resolution 5.8mm drivers push an extended high-frequency range, and the result is clear vocals, deep bass, and a wide soundstage. Our sound score sits around the 63rd percentile, which sounds middle of the pack until you read the actual owner feedback. Multiple people specifically call out the clarity and separation. Snapdragon Sound support doesn't hurt either, assuming your phone supports it.

Battery life is the performance elephant in the room. 6 hours of continuous playback with ANC on is not great, and 18.5 hours from the case falls well short of what we see from competitors in this tier. The Qi charging on the case is a nice touch, but it doesn't make up for the core numbers. And the left earbud charging issue is not a one-off complaint. Several reviews describe the same failure, where the bud needs careful reseating every single time just to charge. That's the kind of problem that turns a daily driver into a source of low-grade stress.

Put this next to the Sony WF-1000XM6 and the trade-off gets clear fast. Sony wins on ANC and battery, two categories where the ATH-TWX9 has clear weaknesses. But several owners report the Audio-Technica beats Sony on out-of-the-box sound quality and fit flexibility. The Technics EAH-AZ100 is another strong alternative for people who want premium sound with fewer reliability headaches. And if you're deep in the Apple ecosystem, the AirPods Pro 3rd Gen remains the seamless choice for calls and device switching.

The Soundcore P31i and EarFun Air Pro 4+ sit in a totally different price class, but they're the move if you want reliable ANC and battery without the premium sound obsession. They don't match the ATH-TWX9 for pure audio quality, but they also don't ask you to baby a charging contact every night. The Audio-Technica wins on character and sound, but loses on the boring daily stuff that actually matters when you're three months into ownership.

Pricing here is all over the map, and that spread matters. In EUR, we see EUR 303 to EUR 375 across three European listings. That's a EUR 72 gap for the same product, so if you're buying in that market you really need to shop around. The lowest EUR 303 listing is the one to look for because at EUR 375 this gets much harder to recommend.

The core tension is that the sound quality can absolutely justify the price for the right buyer. But the average battery life, mediocre ANC in real-world use, and the reported charging problem all undercut the value proposition. You're paying Sony-tier money for Audio-Technica-tier reliability at the moment. The feature set, with things like 360 Reality Audio and the sterilization case, does add genuine value, but those are perks, not the main event.

The Audio-Technica ATH-TWX9 is one of those products that gets the important things really right, then stumbles on the basics. The 5.8mm high-resolution drivers deliver genuinely lovely sound. The fit system, with four tip sizes and three stem lengths, gives you twelve combos to play with. And the charging case even zaps the earbuds with a deep-UV LED to kill bacteria. Audio-Technica clearly sweated the details here.

But the details they missed are the ones you hit every single day. Battery life sits at 6 hours from the buds and 18.5 more from the case. That lands around the 15th percentile in our database, which is rough for a premium set in this price range. And while the digital hybrid ANC has five preset modes plus an adaptive option, owners consistently say it struggles with wind and body noise. That's a weird gap for a feature this heavily marketed.

The real story is the split personality. Our data shows connectivity at the 96th percentile and ANC hardware at the 93rd, yet user sentiment sits at just the 32nd. Owners love the sound, the comfort, and the premium feel. They're way less thrilled about charging reliability, call quality, and the ANC's real-world performance. So this is a set for people who want great audio first, and are willing to put up with some quirks in exchange.

Skip this if you rely on earbuds for phone calls. The robotic audio and connection drops that owners report would make this a frustrating daily driver for business use. The Apple AirPods Pro 3rd Generation remains the benchmark for call quality in this category, and even Sony's WF-1000XM6 handles calls more consistently. If you spend a chunk of your day on Zoom or phone calls from your phone, this is not the pair for you.

Also skip it if battery life and ANC are your top priorities. The 6-hour bud battery and 18.5-hour case put this at the bottom of our rankings for premium true wireless, and the noise cancellation's outdoor performance doesn't justify the premium price. For commuters and frequent flyers who need long stretches of quiet, the Sony WF-1000XM6 or Technics EAH-AZ100 will serve far better.

If you're an audio-first buyer who values sound signature and fit over everything else, the ATH-TWX9 absolutely delivers. The high-resolution drivers, the wide soundstage, and the twelve fit combinations make this one of the more satisfying listening experiences we've seen in this category. Just know you're signing up for some compromises on battery and ANC to get it.

For commuters, frequent callers, or anyone who wants a set-and-forget pair of premium earbuds, this gets harder to recommend. The charging issue, while not universal, is enough of a pattern that we can't ignore it. And the call quality complaints are a real liability if you take calls on the go. At the right price, especially that lower EUR 303 listing, it's a solid buy for the sound-obsessed. At the top of the range, it faces stiff competition.
