TEAC introduced a couple of weeks ago in Japan new high-end bone conducting headphones dubbed HP-F100.
The TEAC HP-F100 bone conducting headphones feature a wide range of frequencies ranging from 25Hz to 25kHz. The lightweight and foldable headset is bundled with a personal amplifier that delivers up to 0.76W to each channel.
The battery life of the TEAC HP-F100 Hi-Fi Filltune headphones is 10 hours. This HiFi bone conducting headset is not a low-cost gadget. Japanese gadget exporter AudioCubes sells them for $499.
