1 out of 5 eggsQuality parts for the most part. Poor design.

Pros: Comes with power adapters for every country in the world. Way more than you will ever need.
Comes with a very nice carry case.
The battery is changeable and can be charged outside the headset. That is good because you will need three batteries to keep the headphones operational throughout the day.

Cons: Notice in the Pro section that nothing is said about the headphones themselves. That speaks volumes.
The materials are top quality. Unfortunately that does not help the poor design and for when (not if) they do snap in half.
The ear cans will probably fit if you are under 5 feet tall. Anyone over that height will be folding their ears before slapping the can over it so you have a tight fit. Quickly becomes hot and uncomfortable.
Any but the most gentle of head turning will have them sliding off your head. Even the movement of cooking will slide them off.
Noise canceling? Never seemed to notice much (any) cancellation.

Other Thoughts: Flat repair cost for this unit is $125. That is very steep for a headset that, even when working, you just are not happy with. I chose to give them away and spend that money getting something better (not hard).

I do not recommend the entire brand. At all. Ever.

1 out of 5 eggsTotally not worth it

Pros: Decent sound


Lots of features

Cons: Battery falls out a lot. For no reason at all.

Bluetooth cuts out about once every 3 minutes.

Noise canceling (when turned on) briefly turns off between songs causing a popping noise.

Noise canceling hardly works at all.

Noise canceling button has stopped working after a week. I can't press it at all. There's no clicky-ness to it.

3 out of 5 eggsDisappointing for Sennheiser

Pros: These are lightweight, comfortable, and the sound is pretty good. Definitely not as good as a wired set for the same price, but really good for being Bluetooth.

Cons: Poor connection between battery and headset. Battery falls out easily if you bump any part of the headphones on anything. SRS doesn't sound that great, and noise canceling is almost worthless.

3 out of 5 eggsComfortable, great noise cancelling

Pros: Very comfortable fit. The cans are a little smaller than what I'm used to for circumaural headphones, but my ears still fit. They fit snugly without pinching, and are cushioned very well all around. Controls are easy to use, and button responsiveness is good. The battery is removable, which is a plus.

Sound wise, they are very clear and the highs are crisp without presenting themselves as too bright. Mids are just as clear without being muddled.

Cons: Horrible bass response. It's just not there. When adjusting the 10 band EQ on the player to compensate, the bass just begins to show but it's turned up so high the player tries to keep it from clipping which results in the player muting bass frequencies. Turning on the SRS on the headphones results in muddling and brightness in the mid to high range with an over-done spatial surround effect. In short, there seemed to be no way to get good deep notes to play at the same volume or clarity of the rest of the frequency band. This was apparent in all types of music and sources - Classical, classic rock, r&b, jazz, rock, metal, progressive, techno... mp3, m4a, flac. Used 3 different devices for play back too. My Tablet, LG G3, and i Phone 5S. Used default music players, RocketPlayer, PowerAmp Pro, etc... Nothing would bring balanced bass to these.

Other Thoughts: I would absolutely LOVE these if they had any bass capabilities. I'm not a bass addict, I just like balanced and well presented audio.

5 out of 5 eggsAmazing!

Pros: Great Battery Life. Bluetooth to ANYTHING CPU/Phone with mic (Make calls listen to music) does it all Audio boost the SRS works great.. takes reduced quality MP3's and gives them a lift.. Better sound than any corded device I own. Paired very easily and is of a very solid construction. I have a large head and they fit great and I blast them at work and until I take them off people sitting around me have NO IDEA how loud it really is (Until that soft leather seal around my ear is broken) comfortable and light weight. You need a Bluetooth connection if you do not already have one (like an older machine or desktop without one built in) but they are cheap and easy to install so not an issue by any means. They also collapse into an awesome case that comes with all the extras and charging cords and connectors to wire it if you need to go wired! Lots of extras included.

Cons: Expensive! But get what you pay for!

Other Thoughts: I bought them before the price drop and I would do it again!

5 out of 5 eggsGreat.

Pros: Expectations met. You could get better audio quality for the same price with a wired set, but for Bluetooth these are remarkable. Probably the best wireless headphones on the market. These make wired beats studio headphones sound like cheap buds in comparison.

Cons: Not so hot with SRS.

Other Thoughts: Pricey, but when you consider the extras you're getting, and the price you'd pay for a set of good cans with an amp to do them justice, I'd say these are appropriately priced.
