⭐ Why choose this model?
By choosing the STEREOMAN ISI 3, you gain unparalleled equipment that solves the common problem of listening to TV loudly. It's excellent support, especially for the elderly or those with mild hearing loss.
Intuitive operation, no need to interrupt your movie to charge (thanks to the second battery included), and absolutely lossless sound from the optical input outclass regular Bluetooth headphones.
• What exactly does microphone mode mean in headphones?
The headphones have a special button. When you press it, the sound from the TV is muted and the sensitive microphone built into the headphones is activated. It begins to "collect" sounds from the room and transmit them directly to your ears.
This allows you to talk to someone in the room without removing the earbuds.
• How long do I have to wait for the device to charge after a long movie?
You don't have to wait at all! Because the set includes two batteries, the second one can be permanently charged in the base. When the earphone battery runs out, simply swap it with the one in the base and continue listening without interruption.
• The earphones weigh 64 grams. Will they fall out of your ears?
Quite the opposite. The included replacement ear tips allow you to adjust the size of the "elastic" to your ear for maximum comfort.
