The Good Excellent sound quality, especially at the low-end. Strong hands-free calling performance. Noise-blocking sufficient for everyday situations. Affordable.
The Bad Can be uncomfortable after long periods of wear. Not compatible with all brands of mobile phone.
The Bottom Line Compared to the headphones bundled with Apple's iPhone 3G the MM 50s are light years ahead. Exceptional sounding bass and its affordable price tag make the MM 50 a great choice for replacing those dodgy Apple ear buds.
Sennheiser MM 50 for iPhone
Out of the box the MM 50s are an unremarkable looking set of headphones, as most in-ear 'phones tend to be. They feature an asymmetrical cable design with 1m and 1.3m length cabling, in-ear headphones with rubber tips and a small receive-call button and microphone located at the position where the cable separates for each ear, sitting on your shoulder just below your chin.
Sennheiser bundles three sizes of rubber ear-buds with the MM 50; small, medium and large. As with most in-ear headphones the MM 50s take a bit of wearing to get used to, and we don't feel the headphones are comfortable enough to wear for more than a few hours. They are very lightweight though, making them perfect for wearing to the gym, if you don't mind the small microphone bobbing about as you jog or cycle.
With the assistance of the rubber ear tip, the MM 50s offer what Sennheiser describes as "noise blocking". While this isn't complete noise cancellation it does make things sufficiently quiet to block out the jabbering of the various "friendly" strangers you tend to encounter on public transport, or dare we say, at the office.
