The Sennheiser MX W1 is able to wirelessly connect to an MP3 Player, but it does not use any Bluetooth at all. Instead, it relies on Kleer corporation’s digital transmission technology, which uses the same 2.4 GHz range, but has better streaming of CD-quality sound for your ears.

The user needs to attach a transmitter to his or her MP3 Player via headphone jack. In fact, I believe these wireless headphones will work for any device that has a headphone jack.

It doesn’t look like the transmitter is powered by the MP3 Player or other electronic device, as you will also have to charge the transmitter and earbuds. The transmitter will last for about 10 hours, while the earbuds can last 3 to 5 hours. The headphones come with a special carrying case with a built-in battery that allows a full recharge of the earbuds three times.

Unfortunately, this wireless technology does not come cheap. In this case, this Sennheiser MX W1 will cost about $499.99.
