Technics EAH-AZ100 Verdict

Who it fits

Technics EAH-AZ100 is the premium sealed earbud for buyers who rotate among several devices and want long single-charge ANC runtime without locking into one ecosystem.

The exact information we checked specifies 5.9g per earbud, a 42g case, 10 hours with ANC on / 12 hours with ANC off, up to 28 hours case-inclusive with ANC on, three-device multipoint, SBC/AAC/LDAC/LC3, wireless charging and IPX4 earbuds.

That combination gives the AZ100 a particularly clear work-plus-music role. The product does not need an invented sound-quality crown to justify itself; three-device switching and 10-hour ANC sessions are already meaningful.

What changes the decision

Three-device multipoint is the defining workflow feature

The AZ100 supports multipoint with up to three devices.

That matters if your real day involves, for example, a work laptop, personal phone and tablet or second computer. Instead of treating device switching as a generic checkbox, Technics gives it a concrete maximum.

If your use is one phone and nothing else, this feature should receive little weight. In that case, battery, fit, charging and current price become more important.

Ten-hour ANC battery is a strong uninterrupted-session number

Technics governs 10 hours with ANC on and 12 hours with ANC off.

With the case, ANC-on use is stated at about 28 hours.

For flights, long office days and extended listening, the 10-hour earbud figure is more important than the case total because it determines how long you can stay out of the case.

This is a tangible advantage over premium sealed products at six or eight ANC-on hours, without requiring any subjective performance ranking.

Broad codecs matter only when your source supports them

The codec list is SBC, AAC, LDAC and LC3 over Bluetooth 5.3.

That gives buyers using compatible Android phones or specialist sources more options than a narrow codec set. It still does not prove that the AZ100 sounds better than Sennheiser, Sony or Bowers & Wilkins.

If you cannot name the source-device codec you care about, multipoint and battery are probably more meaningful decision factors.

Charging behaviour supports the long-session role

Wireless charging is verified.

Fast charging is rated at 15 minutes for around 90 minutes of playback, while a full charge is at approximately 2 hours.

That means the AZ100 is not only long-running; it also has conventional daily top-up convenience. Buyers who routinely forget to charge should still compare quick-charge recovery with nearby products rather than looking only at the full battery number.

IPX4 is adequate for everyday exposure, not a sport-secure promise

The earbuds are rated IPX4.

That is a useful sweat and splash boundary for commuting and ordinary exercise. It does not establish the same level of ingress protection as higher-rated rivals, and it does not prove physical stability during high-motion training.

If running is the primary job, consider sport-secure earbuds instead of assuming a premium sealed TWS will stay put.

The physical package is relatively light, but comfort cannot be inferred

Each earbud is 5.9g and the case is 42g.

Those numbers support portable carry and provide a useful comparison point. They do not tell PIQSY whether a particular ear will find the shape comfortable.

The architectural question remains more important: buyers who dislike sealed tips should move to open-fit or open-ear products.

The premium alternatives also solve different problems rather than forming a simple ladder. Sennheiser MTW5 trades some ANC-on session time for a user-replaceable battery and larger total-case reserve. Pi8 uses its case to bridge wired sources. Sony WF-1000XM5 keeps the workflow more conventional with two-device multipoint and broad codec support. AZ100 is strongest when the third simultaneous device and 10-hour ANC-on session are things you will actually use.

That distinction matters because premium TWS prices can encourage buyers to compare feature totals instead of routines. A buyer with one phone gains little from three-device multipoint; a buyer moving among a work laptop, phone and tablet can experience the benefit every day. The hardware has not changed, but the value of the feature has.

Who should choose something else

Change direction when serviceability, case retransmission or ecosystem integration matters more.

• Choose Sennheiser MOMENTUM True Wireless 5 when a user-replaceable battery and 40-hour total ownership profile matter more than three-device switching.
• Choose Bowers & Wilkins Pi8 when USB-C/3.5mm charging-case retransmission solves a specific travel or legacy-source problem.
• Choose Sony WF-1000XM5 when 8-hour ANC battery, multipoint and a neutral Sony route fit better than three-device rotation.

If you need sport hooks or continuous open-ear awareness, change form factor instead of comparing premium sealed earbuds indefinitely.

PIQSY conclusion

Technics EAH-AZ100 is the premium sealed earbud for buyers who want long ANC sessions and genuinely useful multi-device switching.

The strongest version checked reasons are 10-hour ANC-on battery, three-device multipoint, broad SBC/AAC/LDAC/LC3 support, wireless charging and a relatively light 5.9g earbud / 42g case package.

The main trade-off is IPX4 protection and the usual sealed-fit dependency, not an obvious lack of features.

For a buyer rotating across several devices, Technics has a specific workflow advantage. For a one-device listener, that advantage shrinks quickly and other ownership factors should decide.
