Technics EAH-AZ100 vs Bowers & Wilkins Pi8

What you'll actually notice

Both are premium neutral sealed ANC earbuds with multipoint and wireless charging, but Pi8's case changes the comparison.

Technics EAH-AZ100 is 5.9g per earbud with a 42g case, rated for 10 hours ANC-on, and supports three-device multipoint plus SBC/AAC/LDAC/LC3.

Bowers & Wilkins Pi8 is 7g per earbud with a 46g case, rated for 6.5 hours ANC-on, and its case can retransmit audio from USB-C or 3.5mm analogue sources. It also supports aptX Lossless, aptX Adaptive and aptX.

That creates a clean split: Technics for long normal Bluetooth sessions across several devices; Pi8 for buyers with awkward wired sources that the case can bridge.

What changes the choice

Will the retransmission case solve a real source problem?

Pi8's case accepts USB-C and 3.5mm analogue audio and retransmits it to the earbuds.

Technics does not have the same case-retransmission feature.

What this means: Pi8 can make aircraft entertainment, older players or specific work devices easier to use without plugging a cable into the earbuds.

Switch when: choose Pi8 if you can name sources you will repeatedly connect to the case. If the case will only charge the earbuds, much of its differentiation disappears.

How long do you need ANC to run without the case?

Technics is rated for 10 hours ANC-on.

Pi8 is rated for 6.5 hours ANC-on.

What this means: Technics offers substantially longer uninterrupted ANC runtime.

Switch when: choose Technics for long work blocks or flights where returning the earbuds to the case is inconvenient. Choose Pi8 if 6.5 hours is sufficient and retransmission matters more.

Do you rotate among three Bluetooth devices?

Technics supports three-device multipoint.

Pi8 supports multipoint, but its current exact record does not state a three-device maximum.

What this means: Technics has the clearer workflow for users juggling phone, laptop and tablet.

Switch when: choose Technics if the third simultaneous device is something you will actually use. Otherwise, Pi8's source-bridge case may be more distinctive.

Which codec family matches your devices?

Technics supports SBC, AAC, LDAC and LC3.

Pi8 supports aptX Lossless, aptX Adaptive, aptX, AAC and SBC.

What this means: the two earbuds target different compatible-source ecosystems.

Switch when: choose Technics if LDAC/LC3 is a requirement; choose Pi8 if aptX-family support is more relevant. Codec lists are compatibility signals, not sound-quality rankings.

Do weight and ingress change the decision?

Technics is 5.9g per earbud / 42g case with IPX4 earbuds.

Pi8 is 7g per earbud / 46g case with IP54 earbuds.

What this means: Technics is lighter; Pi8 has the stronger dust/splash rating.

Switch when: choose based on which physical property matters. Neither figure proves comfort or sport security.

The case-retransmission feature also changes how to think about value. Pi8 can effectively replace a separate Bluetooth transmitter for some aircraft or legacy-source setups, so its shorter battery is easier to accept when the case removes another accessory or cable problem. If you never encounter those sources, that same feature becomes mostly dormant hardware and Technics' longer battery and three-device switching become more broadly useful.

Wireless charging is shared, so it should be removed from the deciding column. Likewise, both already qualify as ANC true wireless. The useful comparison is not the number of premium features; it is whether you need three live Bluetooth devices and long sessions or a case that bridges wired sources.

The practical choice

Choose Technics EAH-AZ100 when long ANC sessions, lighter hardware and three-device switching are the everyday priorities.

Choose Bowers & Wilkins Pi8 when the USB-C/3.5mm retransmission case solves a repeated travel or source problem and aptX-family support fits your devices.

If you would never use the retransmission case, Technics' 10-hour battery and three-device workflow become much harder to ignore.

There is also a straightforward portability trade. Technics is lighter at both the earbud and case level, while Pi8 accepts a little more hardware in exchange for the retransmission case and stronger IP54 earbud rating. That does not make Technics more comfortable or Pi8 more durable in every situation; it simply means the extra Pi8 capability comes with a slightly larger physical package. Buyers should accept that package because they plan to use the case function, not because the product sits in a premium tier.

When to choose Technics EAH-AZ100

• Ten-hour ANC sessions matter.
• Three-device multipoint is useful.
• Lower earbud and case weight matters.
• LDAC or LC3 fits your sources.

When to choose Bowers & Wilkins Pi8

• USB-C/3.5mm case retransmission is useful.
• aptX Lossless or aptX Adaptive matters.
• IP54 protection is valuable.
• Six-and-a-half-hour ANC sessions are sufficient.

Choose neither when

Choose neither if you need sport-secure retention, open-ear awareness or a phone-ecosystem-specific route.

PIQSY conclusion

Choose Technics when 10-hour ANC battery, three-device multipoint and lighter hardware matter; choose Pi8 when its USB-C/3.5mm retransmission case and aptX-family source flexibility solve a real source problem.

The case is Pi8's clearest reason to win this comparison; if it is unused, the decision shifts toward Technics.
