The K371-BT Professional Bluetooth Closed-Back Studio Headphones from AKG are designed to offer the same acoustic performance (or voicing) as the wired K371 and features 50mm custom drivers, a 5 Hz to 40 kHz extended frequency response that follows the Harman Target Curve, AAC and SBC codecs, and a battery life of up to 40 hours. They can be used to stream audio from your studio applications, smartphone, tablet, MP3 player, or computer. The K371-BT headphones are built with gesture control and Bluetooth 5.0 connectivity. No additional DSP is on the Bluetooth input, so the sound is naturally reproduced without coloration. With its foldable design, the K371-BT headphones can easily be taken anywhere.
