Battery Life & Wired Backup

The EOKIO H9 over-ear headphones deliver up to 78 hours of playback from the built-in 600mAh battery. A supplied 3.5mm audio cable enables wired listening when the battery is depleted. This makes the set practical for long journeys or extended work sessions without frequent recharging.

ANC Performance & Connectivity Profile

Active noise cancellation rated at 45dB reduces ambient sounds such as traffic or office chatter. Bluetooth 6.0 supports dual-device pairing so the headphones can stay linked to a phone and a tablet simultaneously, although audio plays from only one source at a time. Buyers who require higher isolation levels or simultaneous multi-device audio output should consider other models.

40mm Driver Specification

The 40mm dynamic drivers are the core determinant of sound character, producing clear treble, balanced midrange and rich bass. This driver size defines whether the tonal balance matches a listener's preference for music, movies or calls.

Questions about this item

Should I pick the 78-hour battery or the 45 dB ANC mode for longer trips?

The 78-hour figure is total playtime with ANC on; the 45 dB rating shows how much ambient noise is reduced. Both are available together — you don't choose one over the other.

What does the 45 dB ANC rating mean when I'm on a plane?

It indicates the headphones can cut low-frequency cabin noise by up to 45 dB, so engine hum becomes a faint background instead of a roar.

How does Bluetooth 6.0 affect the wireless range and audio quality?

Bluetooth 6.0 provides a faster, more stable link with lower latency, supporting dual-device pairing so you can switch between phone and laptop without re-pairing.
