Description
The Aceline BT-212 rev2 wireless/wired headphones support two connection methods to audio sources: via Bluetooth technology with an operating range of up to 10 m, or using a 1 m cable with a 3.5 mm jack connector. The model features soft on-ear eco-leather ear cushions that provide a comfortable fit for multi-hour listening sessions. The black design of the headphones is enhanced by multi-colored backlighting. A foldable design ensures compact storage in a bag or backpack. The Aceline BT-212 rev2 headphones feature a closed-back acoustic design that attenuates ambient noise during music playback. Audio clarity is delivered across a frequency range of 20-20000 Hz. For voice communication, an integrated microphone with a sensitivity of -42 dB is built into the housing. A volume control wheel is located on the ear cup. Integrated buttons allow turning the headset on and off, controlling music playback, and answering or ending incoming calls. When used wirelessly, battery life reaches up to 25 hours thanks to the 750 mAh battery.
