It's never an easy decision to spend $350 on a set of cans, but if you're going to, you could do a whole lot worse than the Momentum – we see people do it every day.

Clear with solid range; Balanced sound for all genres; Noise isolation works well; Lightweight; Thoughtful and elegant design

Not foldable; A little pricey

With so many options in the premium headphone market, it can be easy to get lost in the background noise. Sennheiser's new Momentum headphones dispel the aural flotsam with a luxurious, lightweight design and the company's high-quality sound. At $349, these cans are pricey, but they're worth it.

Stylish lightweight frame; Rich and balanced audio; Comfortable fit; Secure lock audio cables

Expensive; In-line media controls are iOS-exclusive

Sennheiser has extended its over-ear and on-ear Momentum headphone line into the in-canal earphone realm. The $99.95 Momentum In-Ear earphones are significantly more affordable than the previous Momentum headphones, but they still come with an air of luxury thanks to their simple, elegant design.

Powerful audio performance with robust bass response and bright highs; Lightweight, elegant design; Excellent carrying case

Can be too bright at times; Only comes with two pairs of eartips

The sheer scale of the headphone market - something I have been banging on about for some time - was finally given some supporting numbers recently. At a recent press launch (ironically not for the Sennheisers), the sales figures for the UK suggests that 12 million over ear and in ear headphones...

The Momentums are the perfect pair of on-ears for the dapper man about town

Great pair of phones, I can say that if I ever get a pair of over ear headphones it would probably be from this brand. I have never heard someone say that they don't trust sennheiser in person, and I can now see why.

These are some great headphones, for $100 I wouldn't have bought any other pair; They don't have a perfectly flat sound like some people may prefer, but for my taste in music its great.

Not necessarily a con, but its not worth the time to put the headphones back in the case, I only use the case for traveling; Buttons don't work how they should on HTC 816, but that was to be expected.

I have owned a lot of headphones in my lifetime. Sound Quality: After listening to a large variety of high-end headphones: Beats offers an interesting "fun" sound for R&B, Hip-Hop and Pop, but these headphones offer you a broad range of accurate frequencies across the spectrum for listening to Jazz,...

True Sound

Need a travel case

At nearly 300 USD, the Momentum True Wireless are not a cheap, throwaway pair of wireless earphones. Do they sound like a 300 USD product When compared to top performing wired earphones in that price range, no, not entirely.

Feature set (Transparent Hearing esp.) – Refined tune – Amazing connection strength through obstacles

Will only pair with one device at a time – Underwhelming battery life – Touch controls are a mixed bag
