Much to most people's annoyance, Apple decided to give the iPhone a recessed headphone input, ensuring standard 'phones simply wouldn't fit in the connection.
Still, this allows headphone manufacturers to expand their ranges with iPhone-compatible cans, like these, the Sennheiser MM 50 iP.
Part of the CX Hi-Fi range, the £50 'phones will fit the iPhones under the sun and the rumoured 3G model around the corner.
As well as being headphones, the MM 50 iP also work fine for taking your calls, equipped as they are with a microphone and control buttons for the phone functions.

Naturally Sennheiser is confident that they will provide a sound quality upgrade on the freebie cans – and we should think so, too.
The MM 50 iP deliver a frequency response from 18 - 22,000 Hz, have a 16 ohm impedance and a sound pressure level of 106 dB.
The cans are supplied with three different sizes of ear adaptors, each boasting "high isolation against environmental and ambient noise".
Out now, the Sennheiser MM 50 iP will set you back £50.
