Wireless on-ear headphones for daily listening
The iLive IAHB48MG connects via Bluetooth for cable-free use and includes a 3.5mm aux input for wired playback. On-ear controls handle volume, playback, pairing and phone calls, while voice prompts and LED indicators confirm status. A built-in microphone supports hands-free calls during work or travel.
Bluetooth range capped at 33 feet
Wireless operation works within 33 feet of the source device, so the headphones suit desk or couch use but not whole-home roaming. The rechargeable lithium-polymer battery delivers up to 5 hours of playtime before requiring a Micro-USB recharge, limiting continuous sessions. Aux input bypasses the battery for unlimited wired listening.
40mm drivers tuned to 20Hz-20KHz at 32 ohms
The 40mm driver units cover the full audible band from 20Hz to 20KHz with a 32-ohm impedance and 102dB sensitivity at 1kHz. This specification determines loudness and tonal balance for music, podcasts and calls. Buyers needing longer wireless endurance or larger over-ear cups should consider other models.

Questions about this item
How do I decide between wireless and wired listening with these headphones?
Pair them over Bluetooth for up to 33 feet of cable-free use, or plug in the included 3.5mm audio cable when you want a direct connection or the battery runs low.
What does the 102dB sensitivity mean when I'm actually wearing them?
At 1kHz the drivers produce 102dB SPL per milliwatt, so typical phone or laptop output reaches loud listening levels without needing a separate amplifier.
Which Bluetooth profile handles the audio streaming and what does it support?
The A2DP profile carries stereo music wirelessly, while the built-in microphone and on-ear controls manage calls and playback without touching your device.
