All the features you desire except one

I got this on a black friday sale, and they are by any means not bad headphones. They are comfortable, the noise cancelling is fantastic, great controls, super portable and easy to sync. They have all of the quality of life features you could ever desire. There is only one downside, the sound quality is really not that great. Of course, they do not sound bad but they leave a lot to be desired. I had some cheaper Bose headphones but they broke so I thought of this as an upgrade but I was a bit disappointed. The sound is very clear but it lacks any kick on the bass. The treble and mids are alright. I'd recommend these if you are looking for something nice to travel around or maybe work out at the gym, or even just for the noise cancelling as it is probably its best feature.

Outstanding Quality for the Price

I'm really happy with this wireless headset, it screams outstanding value! Great product features like NoiseGard (noise cancelling), 25 hour battery, folds up, comes with a cable for wired listening, & very immersive, clear audio quality that's good for any genre. 5 Stars. Thank you Sennheiser!

The Reliable, Swiss Army Knife of Headphones

As the title says, this headset does everything I need it to I'm a student & musician. I needed a headset that I could use to play guitar on but I also needed it for taking to school while on transit. Wireless features with reliable Bluetooth seemed important. I wasn't looking for Noise Cancellation (since this feature is expensive) I just wanted something sound-isolating enough. This set does it all. I would hate myself if I spent 100's on a set that looked good or was part of the popular consensus (Bose or Beats for example). So I go to Best Buy and try these on. Though the display isn't magnificent, Sennheiser makes a huge punch in sound quality and build. They actually look really good too when put on. Then, I compare this set with others. Sennheiser's HD4.50 have this going for them: - Natural Sounding: With a flat EQ, you can hear the separation in the bass, mids and highs. This set has a clear sound with definitive separation in the instruments. You can hear the strings of the guitars as if you're in the studio. Nothing sounds forced. You can adjust the EQ in the Captune App which is kinda nice. - Controls: Easiest to find and use, on the right ear cup. - Toggle Noise Cancellation: Sennheiser uses NoiseGard ANC. It's amazing for the price! You can toggle this on an off wirelessly which is a huge plus for entering and exiting noisy environments. - Folds Up: This comes with a case and easily fits in my backpack! Overall: Awesome headset. Definitely under appreciated! Would highly recommend to anyone with similar needs.

Too smal to be over-ear

Warning - the ear cups are really small for being over-ear. I find them to be a really odd shape, as if they are too big to be on-ear, but too small to be over-ear. They are fine for a while, but after an hour, it gets pretty painful. I also found the headband to be really tight. I have been getting headaches after extended use. If they fit your ears and head shape, you will love the clear sound quality and the noise cancelling. If they don't fit, none of that matters. They will simply hurt.

Sounds Great

Astonishing bass, good highs and decent mids. If you're in the market for strong bass headphones with noise cancellation and competitive pricing then these are it.

Excellent Sound

I have paired these headphones to my laptop, my Ipad, and my Ipod. They work well with each of the devices and the sound is great . The headphones fit well and are very comfortable to wear for long periods of time if you make sure to extend the headset to lessen the pressure on your ears. The battery life is excellent and they only take two hours to fully charge. I would recommend these headphones to anyone who requires a Bluetooth connected, noise cancelling headset and wants to use them to answer calls as well.

Quite excellent

Fit, comfort and sound quality are excellent. I can wear these for hours in my noisy workshop - the real benefit is that I do not miss incoming calls now! Range is about 30ft from a MacBook - less from the iPhone - perhaps 20ft. No complaints. Compared with the Bose phones, the Sennheiser product IMHO is better built, lighter and the sound seems clearer too.

Great sound, very comfortable, limited to 1 Bluetooth connection

We got this headphone set to watch TV and use with our iPad/iPhone. It is a pain to use with more than 1 device. We first synched with an Aluratek Bluetooth transmitter, and all went well. Pressing and holding the Power button turns the set on. They announce "Power On" to confirm. Another press, and you hear "Power Off". We then synched with our iPad. No problem. Of course, that dropped the connection with the TV. However I expected the headset to reconnect with the TV when we turned off Bluetooth on the iPad. All we got on the headphones was the voice saying "Connection Lost". We had to go through the synching process again. It looks like the headphones can only remember 1 Bluetooth connection at a time - unlike our Bose Quietcomfort headphones, which connect to the last device used, and tell you which device you are connected to. So, 3 stars for great sound and comfort. Docked 2 stars for inconvenience of only allowing 1 Bluetooth device connection.

Great pair of headphones

Pros: -Excellent sound quality -Strong bass when using an equalizer -Great battery life -Bluetooth connection is strong (can usually walk over 25 feet from phone while remaining connected) -Very light design Cons: -Ear pads can get a tad bit uncomfortable after an hours use (seems to be getting better as the headphones are becoming worn in) -The sizing of the pads is also rather small, so more than likely these headphones will sit against your ears rather than encompassing them

Amazing Headphones

Incredible sound, look and feel........ comfortable and light 2 thumbs up!

Excellent Noise Cancelling Headphones

Pairing with Android/Apple works flawlessly. The Noise Cancelling works and its a pleasure to work with some soft music in the background while cancelling out all the other noise. The sound is great, not profiled like some competitors but more natural with deep base with a variety of music genres. Glad I waited till in stock as the price point is amazing for this quality.
