Our Score:


Let's face it; if you've just spent a fair wad of cash on a shiny new Apple iPhone 3G the idea of spending another £100 for the likes of the Etymotic Research hf2 iPhone Headset is hardly ideal. But, if you have any audio quality standards and still want to answer calls your options are pretty limited. If you've already got a decent set of headphones then there are microphone adapters available for a relative pittance, but the potential dubious quality of microphones and cable management issues they create make them an imperfect solution - even the Shure MPA can be awkward to use.

Happily, as is often the case in the headphone market, Sennheiser has filled the middle ground with its new MM 50 iP Headset for iPhone. Based loosely on the company's CX 300 in-ear set, they're available for just under £40 online, though some retailers have them listed for closer to £50. At £40 they represent pretty good value for money, even if CX 300s alone cost only £18, since this is a fully integrated solution with a first generation iPhone compatible plug - we'd probably think twice at £50 mind.

Like the CX 300s, though, there's no case included - something we always like to see. You do, however, get three different size tips ranging from small to large, with medium in the middle - fancy that! They provide a nice, tight and comfortable seal, too. Unlike some in-ear headphones the MM 50s aren't too heavy and are quite small and discreet, so there's no need to feel self conscious when walking the streets.

Moreover, though the sound isolation is still very good, this isn't the most penetrating set so anyone who has been wary of going in-ear should find them a nice gentle introduction. This comfort is aided by a smart asymmetric design, with a shorter wire on the left and a longer one running behind the neck to your right ear. It helps alleviate the unseemly clutter of wires and ensure the extra weight of the microphone doesn't upset your listening.

As for the microphone, it performs pretty well. Stand next to a jack-hammer and you will have problems, but stations, trains and the usual public locations proved no real barrier to intelligible conversations. As is required there's a small button for call and playback control, with one press acting as Play/Pause and a double press skipping tracks - one press also answers calls. If one were being hyper-critical the button would be easier to locate were it proud, rather than flush, but it's there and works just fine.

I don't have an iPhone but I do have an iPod Touch. Would the bass heavy sound that these earphones exert be alleviated a little by setting the music EQ to 'Bass Reducer'?

Quite possibly, yes - but to what extent I couldn't say. In any case, if you're using the touch you may as well look at the CX 300s since they're the same thing sans microphone.

I was using the CX300's on my iPod Touch and picked up the MM50s last week for my iPhone. They do sound different which was a shock as I would say I prefer the CX300's as these are a bit bassy. Overall though its a massive step up from the bundled Apple ones so I'm happy for now. Paid 㿔 online instead of 㿨 from Apple direct so not toooo bad.

Agreed with the general theme here. I find the MM 50 iP's very bassy, too much so for my liking (then again I'm an Etymotics fan) but for a good, well priced alternative to the HF2's these are a steal.

Besides ANYTHING that gets owners away from those shocking white buds should be given a humanitarian award in my eyes...

Wish I had seen the HF2's before now as well as I may well have gotten them instead. Been listening to the MM50's all day now and have to say I have got used to them a bit, but still, very very bass heavy. Strange as all the reviews I read before never said this. Wish I had waitied for the TR Review though.

Hey Andy - great review, but when are you guys going to review the Beats by Dre? desperate for a decent UK review.

I actually think these headphones are not bassy enough and I'm not a massive Dance / Hip-Hop listener. I had a pair of CX300's which died and I then 'upgraded' when I purchased an iPhone and I find the bass on the MM50IP to be lacking. I even sent back the first pair thinking there was a fault but the replacment is the same. Do you think I have two faulty pairs. I'm certainly not looking for too much bass but when comparing them to the CX300s they're definitely not the same.

Hi, I'm a sound engineer, I always use HD25-1's for my work and as result when comes to personal use I look for something a lot more lightweight and subtle. I purchased the MM50 for listening to music on my iPhone. On the whole their pretty good! I do however agree that they are quite keen on 250Hz and lower but I find as most portable music has a rather thin 256 bit rate it's not that bad. Unfortunately, I do have a concern. I'm on my 3rd set in less than a year. The iphone ring on the RCA micro jack (3rd ring) has failed on the last two sets I've had after only 4 months of use. You would think that would only stop the iPhone controls but annoyingly they still work and it the sound that suffers. It goes into a restricted 1 channel mode and is unbearable to listen too! I have been using Sennheiser products for almost 2 decades, they've always been bulletproof! So I'm totally miffed by this consistent problem I have experienced so much so I'm taking it up with my area Sennheiser Trade rep to see if there is a known issue. Anyone else experienced similar?
