On a busy desk, connecting a third device is usually the point where something has to be disconnected. The AZ100 can remember all three as active connections. There’s a tradeoff if high-resolution Bluetooth matters to you, and a more important one if none of the tips seals properly.

Pros
- Three-device multipoint suits a mixed work and personal setup.
- Five tip sizes help fine-tune the seal.
- The case charges on a Qi pad.
Cons
- LDAC playback is unavailable with all three devices connected.
- Battery endurance depends on codec and settings.
Sound & Fit
- Magnetic-fluid driver
- Five ear-tip sizes
Technics made the AZ100 smaller than the AZ80 and added an intermediate tip size. If medium lets bass escape but large presses too hard, that in-between option is worth trying before changing EQ. The snug fit also gives the noise-canceling system a more consistent starting point.
Connectivity
- Three-device multipoint
- SBC, AAC, LDAC and LC3
With a phone, tablet and computer connected, there’s less pairing to manage between a conference call and a film. Technics excludes LDAC when three devices are connected. I’d reserve the two-device setup for a compatible music player and use the three-device mode for a working day.
Battery & Charging
- Up to 10 hours with ANC on AAC
- USB-C and Qi case
SoundGuys measured 10 hours 40 minutes on one charge with ANC enabled, SBC audio and music peaking at 75 dB SPL. That’s a useful long-session result. Switching to LDAC or raising the playback level changes the test conditions, so don’t plan a journey around reproducing that figure. 1
Alternatives
An AZ80 owner already has three-device multipoint. The new fit is a more persuasive reason to change if the older shells pressed on the ear over long sessions. For a new buyer who uses one phone all day, put the fit and battery first: a third connection has little value on its own.
Verdict
The AZ100 is particularly useful when several devices compete for one pair of ears. Set it up around how you actually listen: three connections for convenience, or fewer for LDAC and longer listening sessions with familiar sources.
