Pros small and lightweight but very durable design, comfortable, attractive, compatible with everything, good wireless range, good sound quality
Cons no media controls other than volume/mute, 6 hr battery life, non-collapsible design, occasional "blips" in the audio output, large bluetooth transmitter
Summary I am now convinced that the level of comfort that you'll experience with this device is fully dependent on the size and shape of your head and ears. Most user reviews have cited comfort issues but I've had no problems after long hours of wear.
With the included adapters, the transmitter can be quickly and easily adapted to fit any version of the ipod as well as the Zune (be careful though as I felt like the adapter was going to break each time I swapped from my Ipod Mini to my 60 Gb Ipod Photo). With the included audio extension cable I've been able to use this on my PC, laptop, PSP, TV, etc (virtually anywhere you've got a standard 3.5" jack. Again I'm not an audio nut but these headphones sound great and even include a bass boost feature. Wireless range is also good but fairly standard for most bluetooth devices (30 feet or so). The headset and transmitter connect in seconds and I've had no issues so far.
On the downside, unlike it's predecessor, these headphones do not include media controls (rewind, fast-forward, etc). There are volume up, volume down and mute buttons though but it would have been nice to be able to pause on the fly. The transmitter itself is still a little large but I'll admit that it sits very securely with the right adapter fitted. The battery life is unimpressive at just 6 hrs of continuous use so I end up charging every other day or so. Thankfully the charging cable charges both the headset and the transmitter at the same time. Note that the transmitter has it's own built in power so no more draining of my Ipod battery. My only other complaints are that the headset, while being flexible, cannot be collapsed to fit into my tech carrying case for work and there aren't any (yet) compatible carrying cases. Also, I've detected a strange but occasional "blip" during playback which might be typical of wireless sets I guess.
Otherwise I am rather impressed with these headphones and I highly recommend them.
Pros Good sound and flexable
Cons Huge bluetooth adapter, short battery life, pairing issues, uncomfortable design for most.
Summary Well I thought I would try them out and I am glad I did but they are not at all what I was hoping for. The adapter is quite large (almost the size of another ipod). The battery life is not the greatest at around 6 hours on average for both the blue tooth adapter and the battery within the headphones. Regarding comfort I found them alright which I was worried about the most because it seems a lot of people find these headphones quite uncomfortable. Over long periods of time they can start to pinch your ears though which is a another weakness of these headphones. Sound quality I was actually surprised with. The bass is deep and the highs are very good.
The most annoying problem I found with these headphones was the claimed 33 foot transmission range. The blue tooth headphones would constantly lose the connection and then you would have to attempt to pair the headphones with the adapter. Even when the adapter is within 2 feet the headphones would all of a sudden emit the disconnect sound over the headphones and you would have to attempt to pair them up again. Not the greatest thing to be happening when you are trying to listen to music. Logitech tend to make some high quality products but I think they failed with this one. I found the whole thing quite frustrating and out of the 16 headphones that I own I was the most disappointed with these. They are not something I would recommend. Maybe in the future they will create something better but for now I ended up returning them for a full refund.
Pros Great sound quality, sexy look
Cons Very umcomfortable to wear, stop connecting after a while
Summary I must say in the beginning I found the sound quality great, but when I couldn't adjust them it sucked. When I wanted to lean back the bar (that stuck off my head) would keep me up. Very annoying! Plus after a few weeks they would NOT connect to each other. DO NOT buy for the looks and sound reviews like I did. Unless you have a big head, NOT RECOMMENDED.
Pros sound quality
Summary I was torn if to buy these or not; everyone admitted they sounded great, but half the ppl said they were uncomfortable and the other half not. I was hoping to be in the latter...not. I can barely make it through 30 mins and then they become unbearable to wear. i have tried adjusting, to no avail. unfortunately Buy. com will not exchange for a different model(even though it's only been 3 weeks since shipping), so Im basically 90 bucks out of luck. if u happen to be among the ones that can wear these comfortably, then you'll be probably be happy. they cut out (for a sec or two), but not that frequently to really be bothered by
Pros mobility, easy set up, rocker volume
Cons someone tight after a while
Summary I think these headphones are great for the price...they are fairly comfortable and I have a large head. After a while I might adjust them a little to take pressure off, but they are not as uncomfortable as some have said. The set up is pretty much right out of the box, charge it up and let them go. I tend to work about a 8-12 hour desk job and plug them in every night before I check out and the charge lasts for most of my day, sometimes it will die out on me, but mostly it is. I highly recommend these phones.
