Headphones

With one road-worthy headset, you can listen to music wired or wirelessly, take calls over Bluetooth, cancel 90% of ambient noise, and chat with the person next to you - all without removing the headset.

With the MM 550-X you can switch between calls and music - delivered in superb stereo sound with Apt-X capability, as only Sennheiser knows how - without wires! Luxurious, around-the-ear cups powered by NoiseGard 2.0 eliminates up to 90% of background noise for an incredibly relaxing flight. A convenient TalkThrough function lets you carry a conversation with a seatmate (or teammate) at the push of a button. Selectable SRS surround simulation adds excitement and depth to your audio on-demand.

The invisible microphone ensures that you have the added convenience of taking a call without wires, or hassles - without changing headsets.

Using a closed, around-the-ear design to block ambient noise, the MM 550-X is an ideal companion for the frequent flier or baller. Advanced DuoFol transducers provide the kind of detail and frequency response you would expect from Sennheiser. The easy-to-use control panel is intuitive and simple enough to operate with your eyes closed - a common way of enjoying Sennheiser's world-famous sound quality.

The MM 550-X folds up to fit in any carry-on. The replaceable battery charges via USB or a wall adapter. For situations where Bluetooth is not permitted, you can use the included audio cable for a direct connection - making the MM 550-X at home in any situation where a super quality headphone is required.

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.
