After months of anticipation and rumored released dates that turned out be false, we finally got our hands on the Sennheiser MX W1 wireless earphones.  Available all throughout Europe, perhaps you’ve got your hands on a set too.  If not, check out the review to see if the MX W1 was worth the wait.

The Bluetooth Beat Down

Sennheiser proudly boasts the fact that the MX W1 is the very first true wireless earphones.  And while there is always some distinction between brands of earphones in the way of style and appearance, the major difference here is between technologies: Bluetooth and Kleer.  Unlike the average set of headphones, the MX W1 uses a robust 2.4GHz frequency band to transmit audio to each earplug.  This provides crisp, clear reproduction on your MP3 player that blows the limited bandwidth of Bluetooth out of the water.

Kleer is the mastermind behind this new technology implemented into the MX W1.  Relatively new to the industry, Kleer’s technology was first used last year in RCA’s Jet Stream MP3 player.  The overall product wasn’t well received, mainly because of the poorly designed earbuds, giving little indication whether the underlying technology was effective.  Through a relationship with Sennheiser, Kleer has demonstrated the ability to impress with high quality audio performance.

How it Works

Jamming with the MX W1 is pretty straightforward.  The package comes with a matchbox size transmitter which can be attached to your portable audio player with a sturdy elastic band.  Simply plug the earphones into a 3.5mm socket with the provided cables.  The actual earphones come with internal batteries that can be completely recharged about three times when hooked up to the carrying case which is also a charger.  The earbuds are made with Sennheiser’s “twist-to-fit” technology, meaning all you have to do is twist them into your ear canal, ensuring a snug fit.  There are no extra attachments required and the earbuds stay placed firmly.  We found the MX W1 to be pretty comfortable which is a nice compliment to the booming sound it provides.

The transmitter is rather convenient as it allows you to plug and play with the average audio device.  You can hook it up to your iPod, iPhone and also supply the same audio to two different pairs of earphones.  The battery-equipped carrying case is one of the coolest features, perfect for long trips when boredom threatens to rear its ugly head.


All in all, the Sennheiser MX W1 is a definite winner.  The audio output is second to none, offering deep, thumbing bass and digital CD quality sound.  After trying them out, you’re likely to bury your wired earphones in the drawer or just throw them away all together.  The biggest drawback to the MX W1 is the steep cost of £294.99 - no one said that a finely detailed wireless audio experience would be cheap.  At the same time, Sennheiser’s new product flew off the shelves and sold out almost instantly, indicating that a higher quality of music is in great demand.
