For those with extremely good memories Sennheiser's latest technological tour de force may look a bit familiar...
Yep, the acoustic guru has teamed up with Kleer to launch the 'MX Wireless 1' (MX W1 for short-ish) which it claims are the first pair of wireless earphones to achieve 'Hi-Fi quality' audio (kind of a vague term for those who own Alba or Denon units...).
Behind this jiggery pokery however what we learn is much more specific: transmitting a signal at up to 2.37MBps peak bit rate means in theory the buds should play even the largest lossless tracks without any compression on their way to your ear. Deemed 10x more efficient than Bluetooth, Sennheiser also says the tech has no delay in the audio transmission - a vital factor in eliminating lip sync issues for the rapidly increasing number of people using their players to watch video.
Despite their intimidating appearance, the MX W1's also weigh just 10gms and should last from 10 - 12 hours on a single charge while the matchbox-sized transmitter should prove little hassle. For nauseatingly sweet couples, the transmitter can also send signal to two pairs of MX W1's simultaneously. Oh its 3.5mm jack is slim enough to fit first gen iPhones.
Now here's the 'but' and it's predictability wallet orientated. For whereas Kleer once optimistically thought of shipping its technology for a mere $149 in a deal which included a free MP3 player the optimum nature of the Sennheiser MX W1s means you'll be required to shell out a full £299.99 for the pleasure of owning them (MP3 player of any kind not included).
So how much do you want to straddle that bleeding edge...?
