You've probably heard of Sennheiser. Its headphones and earphones are everywhere from giant multi-brand electronics megastores to that chap selling budget in-ears by the side of the road.

I have been recording and mixing songs for 7 years. Having a Sennheiser is my dream. Now I got that chance to experience this product and I must say that I am fully satisfied with the quality of the sound. It is as if the sound was already set up for auto tuning even if it's not.

Produces quality sound

Pricey for starters

While it may be a bit overpriced, the Momentum 2.0 Wireless is an excellent and well-designed Bluetooth headphone with active noise-cancellation that also offers strong wired performance.

While the Sennheiser Momentum Wireless M2 AEBT doesn't sound as good as the passive Momentum models, it does sound better than any other Bluetooth noise canceler I've heard. I'd characterize it as good upper mid-fi when run passive on the wire, and a notch lower with the power on.

Thumping bass and excellently designed "bright" side with clean vocals make this ear-phone worth buying

Vibrant mids Bright highs Strong cables that are tangle-free Metallic ear pieces Very low distortion even at high volume Good looking (Swaggy) design Wonderful; compact carry case with enough space to store 2 more earphones

A little bit pricey Would expect an additional pair of ear tips Some music tracks can sound too bright

You get what you pay for: The $499 Sennheiser Momentum Wireless headphones are nearly perfect. The design is timeless, albeit a tad understated, and the rich audio with the spacious soundstage is trademark Sennheiser. I also appreciated the quick wireless setup and the intuitive controls.

Rich; crystal-clear audio; Attractive; sturdy design with premium materials; Good active noise cancelling; Easy-to-use wireless controls

Expensive

In-ear headphones are capable of awesome sound, but you might not be aware of that if you're used to hearing music through the cheap sets included with your smartphone. Even a slight step-up in headphone quality can nab you a set that can achieve ideal sound isolation from the outside world.

The Sennheiser Momentum on-ear headphones are accurate in delivering sound quality but it's not designed for long periods of usage. With a price tag of $230, it failed to live up to my expectations.

+ Accurate sound signature; + Old-fashioned retro design

- Pricey for an on-ear headphone; - Discomforting

You put on half and twist the rest on. Not sure if it's my German heritage or Polish ingenuity but it's rather easy. I had to take mine off to check the authenticity of mine so I hope someone else finds this information useful.

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.
