Providing a 30-foot range, you can move freely while taking a call, or listening to your favorite music or movies. Just working on your PC? The Cobalt is also sold with a USB dongle transmitter that allows you to plug into your computer. Incorporating a Lithium Ion battery, the Cobalt gives plenty of airtime. The Cobalt is the first to feature two separate transmitters one with your computer (USB) and the other for your CD, DVD player, or MP3 player allowing for great versatility. The Cobalt can also be used with select mobile phones, utilizing its built-in microphone that allows the user to facilitate two-way communication or couple with the Bluetooth enabled cell phone for calls. The Cobalt allows music lovers to answer calls with the same headphones used for listening to their portable music players.
The behind-the-head design of the Cobalt provides maximum comfort during long listening periods. Foam ear cushions allow for hear-through sound, and its dynamic element provides extended frequency response. The wider frequency response results in better overall sound performance for the Cobalt. For added convenience, push button volume controls on the ear cup allow for easy level adjustment. The Cobalt is also collapsible for protective storage and maximum portability when listening on the go. The Cobalt package includes the stereophone, audio transmitter, USB audio dongle, USB charging cable, AC charging adapter, and audio extension cable. The second transmitter requires (2) "AAA" batteries that are not included.
Built to last, the Cobalt is covered under Koss' No Questions Asked Lifetime Warranty--the only warranty of its kind in the stereophone industry.
Owner Reviews, Ratings, Comments and CriticismIt is nice that it comes with usb adapter and blue tooth adapter so that you can use it with your computer or with audio equipment that is not bluetooth compatable. I use it with my reciever and can listen to my dvds or tv shows. Could be more comfortable.
