Noise cancellation, three-device pairing and flexible charging. Fit and codec choice shape the daily experience.
Researched
Our recommendation
Worth considering if you move between a phone, laptop and tablet. The three-device connection is useful, but comfort, source compatibility and your preferred codec should decide the purchase.
Black EAH-AZ100E-K earbuds with charging case. Battery totals include the earbuds; the case does not add another 28 hours.
- Device connections
- Up to 3 through multipoint
- AAC listening
- Up to 10 hours, ANC on
- Driver
- 10mm magnetic-fluid dynamic driver

Try the fit before judging sound
A secure seal affects bass, isolation and comfort. Try the supplied tip sizes and check both ears separately; one size need not suit both sides. Stop if the fit becomes uncomfortable rather than relying on noise cancellation to compensate for a poor seal.
The app provides sound and control adjustments, but those settings cannot guarantee a comfortable shape. Check the retailer’s conditions for opened earbuds before deciding how you will assess fit.
Move between work and music
Multipoint supports connections to three devices. That can reduce repeated pairing when a laptop call interrupts phone listening. It does not combine three audio streams into a mixer; check switching behaviour with the apps you actually use.
Specialised features depend on the source and connection mode. Confirm codec and LE Audio support for your phone or computer, rather than assuming every Bluetooth device exposes the same options.
Read battery figures by codec
The ten-hour headline uses AAC with noise cancellation enabled. The manufacturer publishes shorter figures for SBC, LDAC and LC3. Volume, calls and operating conditions also affect the result, so choose a charging routine with some margin.
The stated 28-hour AAC total already includes the earbuds and case. It is not ten hours plus another 28. A higher-quality connection setting can be worthwhile, but it should be a deliberate trade against runtime.
Keep the case ready
USB-C and supported Qi charging offer two ways to replenish the case. A wireless pad is separate. Use a suitable certified pad and follow the charging guidance; a magnetic attachment does not establish compatibility.
IPX4 describes splash resistance for the earbuds. It does not make the case waterproof or turn the set into swimming equipment. Dry the earbuds and charging contacts before putting them away.
Choose convenience over a badge
AZ100 suits people who value flexible connections and adjustable controls alongside listening. Compare the functions you need with the price of the exact black model, without assuming the specification list proves superior sound for every listener.
This is a researched guide. We have not tested call clarity, noise reduction or fit. Those experiences remain personal, and published battery figures describe controlled conditions rather than every working day.

A good fit if…
You move between several devices and want adjustable noise control, app settings and a choice of wired or wireless case charging.
Keep in mind
Fit is personal. Codec and spatial features depend on the source, and the longest battery figure applies to AAC rather than every mode.
