It’s the little details that make the Momentum in-ear headphones something special. The acoustic components are made out of stainless steel and contains no plastic, the earbuds are at a slight 15° angle, the left bud has three raised buttons and the right a small R, the magic cable that despite being 1.2 m long never tangles up. The result is a stunning, superb pocket headset with a comfortable fit and great sound.

I started with a generic dirt cheap pair of earphones years ago. They were hooked up to an iPod Nano that went everywhere with me to help mask chronic tinnitus. I upgraded to something a little better every time the last set was irreprebly damaged and the gaps in between upgrades have steadily increased as better quality products last longer.

My last in-ear wired buds of choice was the good quality Sennheiser MM30i set that I was perfectly happy with (their review here). I never considered upgrading because I couldn’t justify the jump in price from under £30 to £70 (mid-range in the £50-100 bracket), but wearing the Momentums for the last couple of weeks made me realise that an adjustment in attitude is definitely required.

I use my in-ear headphones more than any other device I own. They’re in my ears when I exercise first thing in the morning, travel with me for a variety of uses all day and they are often the last thing I put away after listening to an audiobook at night. The Sennheiser Momentum earphones offer excellent quality and durability at a comparatively small price when compared to the cost of other electronics I use less often.

Definitely a cost-effective choice for anyone who listens to a lot of audio and really care about sound quality.

I use in-ear headphones on a daily basis with multiple mobile devices. I listen to an electric music library and audio books whilst pottering about and enjoy relaxing with a streamed film or TV on a mobile device. Mobile device provides instant access almost no matter where I am, but my headset has always lagged a bit behind because I tend to put my money into more serious gear related to big screen TV watching and gaming.

I spend more time plugged into a laptop, phone or tablet than I do with what I think of as more serious hobbies (listening to music ‘properly’ or playing ‘serious’ games at home). I think of listening to music or an audiobook on my phone as inconsequential when in reality, the bulk of my activities are mobile based with audio played through a good, but not great headset.

The M2IEG is a great headset. It can’t compete with headsets in the higher price ranges, but I think it would give any headset in the £50-100 category a run for its money. Speech is crystal clear and distinctive. Music is full-bodied with balanced treble and bass. Ambient sounds are distinctive and well rendered. Although the mid-range is slightly neglected, the sound quality and complexity is fantastic for in-ear headphones. My ears have loved this upgrade.

Highly recommended.
