KOSS has been producing and selling consumer electronics for over 56 years. Koss is regarded for making the highest quality affordable headphones on the market. Now KOSS is taking that experience to the next level with their latest offering, the KOSS BT540i Bluetooth Headphones [$199]. Featuring state of the art Bluetooth® hardware and software that is integrated with aptX® codec technology, the Koss BT540i is the one of the most advanced Bluetooth headphones today. Like being connected? Using the built-in, dual microphones which work in sync to reduce background noise, producing exceptional call clarity, it’s a breeze. I’m really geeked up about the on-board controls that let me shuffle through songs, play or pause music, volume-up, volume-down, and answer incoming calls. They’re outfitted with the all-new precision-tuned Koss PLX40 Dynamic Elements featuring crisp highs, robust mids and smooth lows, perfect for personal listening. Premium leather memory foam cushions close gaps around the ear, creating the perfect seal with an incredibly comfortable fit. I wore these headphones for 4 hours straight, two days in a row with zero discomfort what-so-ever. The built-in lithium-ion battery delivers more than 8 hours of listening time on a single charge. A detachable audio cable is included and can be used as a bypass should the battery run out. The BT540i folds flat and comes with a travel case for easy portability. Also included is a USB cable for on-the-go charging. KOSS BT540i are certainly Uber Apparatus and absolutely the Best of Breed!
