Headphones professional Koss BT540i
Over-ear headphones with wireless audio transmission via Bluetooth or NFC.
The model has a detachable cable and a foldable design, which is convenient for storage and transportation. The earbuds have a comfortable fit thanks to a comfortable headband covered with soft leather on the top and pleasant velor on the inside.
Another important point: KOSS BT540i is not just a headphone, but a headset. There are no microphones on the detachable cable, they are located on the right earcup. There are two microphones, which helps to cut out external noise and improve the quality of speech transmission. The main microphone - voice - is located on the bowl next to the micro-USB input. The second one, used in tandem with the main one to suppress external noise, is located next to the bowl mount and looks like a small cavity in the right earpiece.
