If everyone on the Underground was forced to buy a decent set of earphones, the rest of us poor unsuspecting commuters would no longer be subjected to entire journeys in the company of Bon Jovi’s greatest hits tinnily bleeding into the carriage. So before you find that it’s not just your Bon Jovi album that’s bleeding, you should probably think about getting a set of Sennheiser’s latest fancy new earphones. There’s two on offer, the MX 450 (£14.99) and the MX 550 (£24.99). Both come with two-year guarantees and lots of promises that the sound production will be second-to-none. The MX 550 comes with an in-line volume remote as well.
