I have been looking for this type of sleepwear for a long time but there was always some feature I didn't like.  I like everything about these.

I really like these. Tons of features. Navigating CID and contact list can be annoying though. No dropped calls or audio quality issues which is most important.

More than what I thought it would be like, my only thing I didn't like was the length of time in shipping
I really like all of them

Still getting used to them, but I think I'll like them for my uses.

They work great and i love the feature of being able to turn them all off or on with the click of one button.

I've been using these headphones for about 6 months now and I wanted to go ahead and break down my thoughts/experience with them.

What I like:
  *They fit my head! I've got a big noggin so this is always a concern.
  *The noise canceling works just as good, if not better than the Bose QC2s I replaced with these
  *They're very durable. I'm terrible about keeping them in the case, but they've held up to hundreds of thousands of miles of abuse!

What I dislike:
  *They should have an auto-off feature... I burn through AAAs constantly! I know that's nit-picky but it drives me nuts (it's my own fault...)
  *After ~4-5 hours of wear my ears are hot and throbbing. I assume that's the nature of the beast with noise cancelers.
  *Occasional feedback type noise. I've only noticed this a handful of times, but I've heard definity buzzing/cell-phone type interference

Overall they're great headphones and beat the pants off those overpriced Bose, this is a solid buy. Remeber what B.O.S.E. stand for folks, Buy Other Stereo Equipment.

I read all the reviews and figured this had the least things I hated (I was pretty discouraged at what was out there, especially since my #1 requirement is a digital tuner, this being the only one Sony makes; I can't stand  playing with a dial trying to lock in). I didn't mind so much that I would probably have to prop up the back or leave it on the floor to see the time (you really have to look straight (or down) at it, so with your head on pillow, you have to get up) or that there was no battery back up, but decided its going back when I overslept cause I didn't hear the alarm for 45min. It's soft and puts u in a trance. I tried the radio the next day and I swear it never went off(I used a backup).
I think I'll take my chances with a RCA or Timex and be happy with just a radio when the CDplayer breaks. I guess I've been spoiled by my old one, where I could flick a switch and the alarm would come back on same time, and the volume would get louder in case you had it down the night before.

I like the variety it gives you, and the communication. I don't like the fact that I have to tap it every time

I like these, with all the features available. I got these as a sort of compromise when I really wanted the twice-as-expensive Bose Quiet Comfort noise-cancelling headphones, but I also didn't like that the Bose model wasn't available in a wireless model (which just changed as of this last weekend, when the Quiet Comfort 35s were introduced).  I got these primarily to use at work to block out the everyday music, arguments, and political news (from the perspective I disagree with, of course) blasting from my coworker's office. It works pretty well, though after a while my ears start to ache because despite having an especially small head and ears, the cushions aren't large enough to fit my ears in fully without resting on them at the top. In this regard, I highly prefer the Bose Quiet Comfort. I will probably replace these with the Bose when I can afford them.

Update:  I did purchase the new Bose QuietComfort 35s, and to be honest, they're not that much better than the BackBeat Pros.  The Bose are more lightweight and compact, which I really do like, and fully enclose my ears, but they're more than twice as expensive.  Furthermore, the controls are sub-par: in order to pause/play or jump tracks, you have to feel around with your fingers for a tiny button in between the two volume control buttons and press it one to three times depending on what you want it to do.  The BackBeat Pro controls are much easier and more intuitive.  I quickly got tired of trying to locate that tiny dang button on the Bose QuietComfort.  I just wish I could combine the Plantronics features with the weight/form and fit of the Bose set.  Because the sound quality and noise canceling ability seem nearly equal, I think the price point makes the BackBeat Pro the way to go, and I will probably return the QuietComforts.

I Love them, but I think they are too cool for me. I'm not this hip, but no one needs to know that.

I like them but I hate the reason behind them  There is nothing wrong with them, but the fact that we need to have them is what I hate

They sound great and for the money I feel like you can't beat these things. However, I didn't give them 5 stars because of three small things:
1) I hate that little wire the protrudes from the side. The wire just hangs there and looks very vulnerable.
2) I hate (hate hate) the extra long cord and wish I could roll it up somehow. I used electrical tape to tie it up and what a created is this ball of wires that now weighs down one side of my head. It is def a little annoying.
3) They don't fold up neatly and I hate (hate x3) that I can't take these headphones everywhere with me because despite 3 above mentioned issues(in order of hate severity from least to most btw), I really love these headphones.

1st off these lights are fantastic; they are bright and can be dimmed, there is color, and lots of it, and they are energy efficient. Everything works as advertised. However the reason they don't get a 5 star is the control interaction. When I first used the lights, grabbing the iPhone, bringing up the app, and clicking on or off was kinda neat. But I have come to realize that method is a bit short of total satisfaction. My phone must be locked for various reasons; that extends the time it takes to turn on or off the lights. Nor do I leave my phone on at night; so to turn the lights on in the morning, I have to wait for start-up and log-on. I understand Phillips has announced that a separate device will be available this year that equates to a off-on switch. We'll see how that is, and how much it cost.

Also, there is the suggestion to use IFTTT for alerting or scheduling. Right now, there are lots of conversations about the security aspect of IFTTT. With the recent OpenSSL vulnerability (HeartBleed), I'm more than a bit hesitant to link these various apps together in one place. So, I'm going to stay away from the functionality for awhile.

Overall, the lights are really nice, flexible, and just plain cool.

I like all most everything the gram the color, the only thing I don't like is that the temples are to lose they feel like they are going to fall off my face. Other then that I like them a lot.

I received these as a gift.  Sonically they are very good, as one would expect from Sennheiser.
I gave these a 3 star review because of the design of the controls.  The power button it's nestled in between the volume up and down controls, with a small power icon bump to distinguish it from the volume controls.  The bump is so small it is indistinguishable.  The buttons are do close together as to be difficult to operate.  So, often, when I go to change the volume, I end up turning them off.  A very annoying feature.
I do like the sound.  If I had purchased these myself I would have exchanged them for something else.

I'm at 7 months with my headphones and it has taken me a bit to get used to them. They are very easy to set up, pair and turn on and off but the way the ear buds are designed took me a bit to get used to - I switched out ear bud sizes (included in purchase) and that helped - I love the little loop for glasses to be attached and use that frequently. They charge easily and hold a charge for a while as well.
