Sony WF-1000XM6 vs Technics AZ100 Review: Which Earbuds Win?

Battery performance is where the Technics AZ100 pulls ahead more decisively. With active noise cancellation enabled, the AZ100 delivers around eight hours of continuous playback from the earbuds themselves, and the charging case provides an additional three full charges, bringing the total to roughly 32 hours. Without ANC, those numbers climb to about 10 hours per charge and 40 hours overall. Fast charging is also on board — a ten-minute top-up yields roughly 90 minutes of listening time.

The Sony WF-1000XM6 is respectable here but falls a little short. You’re looking at approximately six hours with ANC turned on, and the case holds another three cycles, giving you around 24 hours total. Turn noise cancellation off, and you’ll stretch the earbuds to about eight hours per charge. Sony includes quick charging as well — three minutes in the case gets you an hour of playback, which is handy for those last-minute dashes to the station.

Where the Sony slightly redeems itself is wireless charging support, which is built into the case. The Technics AZ100 case lacks wireless charging, which feels like an odd omission at this price point. If you’re someone who already has a wireless charging pad on your desk or nightstand, that might tip the scales back toward Sony.

Verdict: The Technics AZ100 wins on raw stamina, but Sony offers wireless charging convenience. Choose based on whether you prioritise longer sessions between top-ups or a cable-free charging experience.

Call Quality and Connectivity

Neither pair of earbuds will let you down on a phone call, but they approach microphone performance differently. The Sony WF-1000XM6 uses beamforming microphones paired with Sony’s noise reduction algorithm. In practice, your voice comes through clearly in moderately noisy environments like a busy coffee shop or a windy street. The person on the other end might hear some background chatter, but your voice remains intelligible and natural.

The Technics AZ100 features Technics’ JustMyVoice technology, which isolates your speech from surrounding noise using multiple microphones and processing. In side-by-side testing, the AZ100 handles chaotic background noise — think traffic or a loud café — slightly better than the Sony. Your voice sounds a touch more compressed, but it cuts through the mess more effectively. For quiet environments, both are excellent.

On connectivity, both earbuds support Bluetooth 5.3 and multipoint pairing, so you can stay connected to your laptop and phone simultaneously. I’ve experienced fewer dropouts with the Sony when walking through crowded urban areas, but the Technics holds its own. Both support LDAC for high-resolution streaming if your phone and music service allow it.

Verdict: Technics AZ100 takes a narrow lead for noisy-environment call quality, while Sony offers slightly more reliable overall connectivity.

App and Software Features

Sony’s Headphones Connect app remains one of the best in the business. It’s intuitive, regularly updated, and packed with genuinely useful features. You get a full parametric EQ, customisable noise cancellation levels, Speak-to-Chat (which automatically pauses music when you start talking), and Adaptive Sound Control that learns your routines. There’s even a feature that analyses your ear shape to optimise noise cancellation. It sounds gimmicky, but it works.

The Technics Audio Connect app is cleaner and more minimalist. You get a solid 8-band EQ, noise cancellation adjustment, and firmware updates. There’s none of the “smart” automation Sony offers, but for someone who just wants to dial in their sound and leave things alone, that might actually be preferable. Some users will appreciate the simplicity; others will miss the extras.

Verdict: Sony WF-1000XM6 wins this round. The app is feature-rich without being overwhelming, and the automation features add real value for daily use.

Which One Should You Buy?

Let’s be honest — neither of these earbuds is a bad purchase. You’re choosing between different kinds of excellence.

Buy the Sony WF-1000XM6 if your daily life involves crowded trains, open-plan offices, or anything else where blocking out the world is your top priority. They’re also the better pick if you value smart features like adaptive noise cancellation and Speak-to-Chat, or if you’ve already invested in Sony’s ecosystem. The wireless charging case is a nice bonus for anyone tired of fumbling with cables.

Buy the Technics AZ100 if you’re the sort of person who sits down with a cup of coffee just to listen to an album from start to finish. For pure sound quality, they outperform the Sony by a noticeable margin — wider soundstage, better instrument separation, and a more natural tonal balance. The longer battery life is a genuine advantage for long-haul flights or weekend trips away from a charger. Just be prepared to carry a USB-C cable for the case.

Conclusion

So here’s the bottom line. The Sony WF-1000XM6 is the safer bet for most people. It does everything well — noise cancellation, call quality, software features, comfort and it does those things with a level of polish that comes from years of iteration. You could hand these to almost anyone, and they’d be perfectly happy.

The Technics AZ100 is for the person who knows exactly why they’re buying them. They’re not trying to be everything to everyone. Instead, they focus obsessively on sound quality and battery life, and in those areas, they genuinely beat Sony at their own game. If you’re the kind of listener who notices the difference between a good recording and a great one, the AZ100 will reward you every single time you press play.

Neither choice is wrong. But if I had to spend my own money tomorrow, I’d grab the Technics and that’s coming from someone who’s recommended Sony earbuds for years. The AZ100 surprised me, and I think they might surprise you too.
