I bought this item not expecting it to be that good. But after using this item each and everyday at work I am really surprised with the headphones. The sound is brilliant, very comfortable and last a very long time indeed.

If you have prejudices against closed headphones, Sennheiser's Momentum is a model that can really open your ears. Literally. The most obvious difference between headphones

Full-bodied and engaging sound

Not foldable

Ultimately, the Sennheiser Momentum headphones produce great bass and are stylish and comfortable enough to wear all day.

Distinctly designed to deliver the best bass tones and overall sound quality; the Sennheiser Momentum headphones improve every music session

Sadly; the Momentums don't fold and have a slightly lower frequency response than other headphones

Great sound for ear buds. Comfortable in my ear and they fit well. Color is nice and the cable seems sturdy. However not ideal buds for when your moving around a lot and walking around often. You can hear the thud noise from the movement of the buds in your ears bouncing around with every step.

I love them. One out of the two cables stopped working, it lasted 2 years. Other than that, great gear, sound quality is top. Not bass heavy, but sound is fine and precise. I mostly listen to electronic music and they deliver.

A bit snug. The point on which reviewers disagree most about these Sennheiser Momentum headphones is how comfortably they fit. Most reviewers find them comfortable and not too heavy. Wired magazine notes that the individual ear cups rotate slightly to "give you a nice seal without too much clamp.

Excellent sound; Great build quality; Stylish design; Good passive noise blocking

Uncomfortable for some users; Cables and connectors may break easily

Very good headphones for the use of their design use is for, And I am very happy with the high quality build quality of these headphones. I highly recommend these headphones, And fantastic wireless sound quality for portable devices. such as my mobil..

These are really really good. Clear sound and great bass. I was worried I spent too much but these are definitely worth the money and don't look / feel cheap at all if you don't use headphones as much as me.

These are really really good. Clear sound and great bass. I was worried I spent too much but these are definitely worth the money and don't look / feel cheap at all if you don't use headphones as much as me. One problem is that I've lost some of the ear buds and I'm not entirely sure how to get more for these, the bottom part by the jack is also worn down already. I do use headphones for about 10 hours a day while moving around so wear and tear is expected. But I was hoping they would last longer than my previous headphones. Therefore my rating is a 4 star.

In conclusion, if you are looking for a sub HK$1000 pair on in-ear headphones, and you cherish the accurate sounds and large range of depth of your music, the Sennheiser In-Ear should be right up there on your shopping list.
