The first part of our 3-part Sennheiser Momentum series headphones/earphones reviews, FunkyKit brings you the Sennheiser Momentum In-Ear review. A big thank you to Sennheiser for sending these Momentum series headphones for our reviews, but

I bought these when my Klipsch S4i started dying (volume is cutting out on the left channel). Fair enough – 7+ years is a long service life for a pair of inexpensive earbuds. My first priority was compatibility with my 3G iPod Shuffle, which needs a 3-button remote to operate.

Fluid; musical sound; build quality

Flat soundstage; uncomfortable ear tips

After less than 3 months of infrequent use and careful storage, only one channel works. I'm taking these back for exchange with a pair that works in both ears. Owing to the appalling quality control, i'm no longer going to buy these as a Xmas present for my wife.

These Sennheisers are the first in-ear model to join the Momentum series, which has helped to establish the company as a top choice for people after stylish headphones with better sound quality than Beats.

Powerful low-register bass; Good detail; Nice mid-range tone; Separate iOS and Android versions available

Recessed mids

Sennheiser's Momentum family goes from strength to strength - here's another impressive addition The Sennheiser Momentum In-Ear Wireless are more of a commuting companion than gym buddy.

Open; lucid sound; Bags of detail; Expressive midrange; Excellent dynamics; Powerful bass

Neckband design won't appeal to everyone; Bass a little overegged

The Sennheiser Momentum In-ear wireless is a testament to the fact that some designs become popular enough to find appeal across brands. The Sennheiser Momentum In-Ear is almost a replica of the LG Tone Infinium, a design that has gradually become popular with a cross section of users from joggers...

Great replacement for the small size ear adaptors that come with the earphones. Exactly like the originals, I lost one and had no more small sizes left so this is great. I was only expecting 1 pair but then when it arrived there was 5 pairs, which made me happy.

All works and has a 45 degree connector which is great for pocket carry sound is great slso

Until earlier this year I thought of Sennheiser for quality headphones, then I reviewed the Flex 5000 which came with a set of earbuds, since then a pair Sports buds and now this Bluetooth offering to give you total freedom of movement.

Excellent headphones with natural sound across the range. So light and fitting that you forget you are wearing them. Easy to sync and easy to use controls on the neckband. One slight niggle is that in busy areas with heavily competing Wi-Fi and other Bluetooth signals the music can get a bit jumpy.
