Wireless earbuds
Got to admit that the Germans come up with some funky stuff. Sure it’s probably just designed in Wennebostel then manufactured in China. But some famous Yankee’s do that too: designed by you-know-who in California, blablabla…
In any case, the Sennheiser MX W1 are a set of earbuds I’d trade in my Shure‘s for. The main feature is the fact that they are wireless and are optimized to deliver sound without distortion and loss over 10m. That’s the distance between the MX W1‘s in your ears and the transmitter connected by 3.5mm jack to your audio source of choice.

The transmitter is the size of a matchbox, doubling as a charger for the earbuds. They will run for a claimed five hours on a single charge. And the transmitter is held to an iPod or other portable by means of an elastic band. Not the most elegant solution…
The Sennheiser‘s are based on technology by Kleer which uses the overcrowded 2.4GHz band in an adaptable fashion, switching among 16 channels to retransmit damaged streams.
The transmitter is able to serve two pairs of earbuds at the same time, so rocking along with someone else is possible, even though onlookers would wonder at a pair of gyrating figures dancing to silence… For the princely sum of roughly USD 600, one may just have to dance in silence for a while. That amount of cash could lead to a serious dent in those plans to buy an amplifier…
