- Smaller brand presence and US service network than Sony, Bose, or Apple
- Stock ear tips can shift over long sessions; fit can be loose for smaller ears

Performance
The AZ100 wins on the things audiophiles and heavy communicators care about. Its magnetic-fluid driver gives a natural, detailed, low-distortion sound that reviewers rank among the best in true wireless, LDAC carries hi-res to Android, and the 6-mic Voice Focus AI delivers the cleanest call audio in the class — a genuine reason to buy if you take a lot of calls. Three-device multipoint and a category-best 10-hour battery make it the best multitasker here. The only place it yields is raw ANC: it’s very effective, especially on planes and trains, but a narrow margin behind the Sony and Bose at peak.
Build Quality
Build quality is solid and a touch lighter than its well-regarded AZ80 predecessor, with no failure patterns reported since its 2025 launch. It’s IPX4 splash-resistant with Qi wireless charging. The two caveats are practical: the stock silicone tips can migrate over long listening sessions (aftermarket tips fix it), and as a sealed earbud the battery isn’t replaceable, so multi-year lifespan is capped like the rest of the category. Technics’ smaller US service network is the other consideration — support is established via Panasonic but less ubiquitous than Sony’s, Bose’s, or Apple’s.
Value Assessment
At $299 MSRP — and frequently $220–$249 on the street — the AZ100 is strong value for what it does best: audiophile sound, the best calls in the class, three-device multipoint, and the longest battery, all for less than the Sony’s MSRP. You give up a sliver of ANC and the reassurance of a big-brand service network, but you gain genuine differentiation. For the audiophile, the call-heavy professional, or the multi-device user, it’s arguably more bang for the money than the flashier flagships — which is exactly why it’s our pick for that buyer.
Who Should Buy It
Audiophiles who want the most natural sound, professionals who take a lot of calls and need the best mics, and multi-device users who’ll use true three-way multipoint — especially Android owners who can exploit LDAC.
Who Should Skip It
Anyone whose top priority is absolute best-in-class noise cancellation (the Sony or Bose), deep iPhone-ecosystem users (the AirPods Pro 3), and buyers who want the reassurance of the largest support network.
Final Recommendation
The Technics EAH-AZ100 is our Best for Calls & Multitasking pick: audiophile sound, the best call mics in the class, three-device multipoint, and the longest battery here, at a street price that undercuts the Sony. Its ANC is a touch behind the leaders and the brand’s support is smaller — so it’s the savvy pick for sound, calls, and multi-device life rather than for pure noise-blocking.
