Pros: Sound quality H2O / Sweat -proof design Touch Controls

Cons: Fit `Disposable'

Overall Review: This BT headset provides quality sound, far superior to any ear-bud that I have ever used. I use this product during intense cardio workouts that result in some profuse sweating. The headset has had no issues with this whatsoever. The touch controls work flawlessly, providing excellent tactile and audio responses. The fit of the headset is just slightly off. As a result, the beautiful bass that the headset produces is not always heard. In my case, I have to apply a slight pressure to properly seat the 'bud' into the ear canal. The result? Wow ... If the fit could be tweaked by the end user ever so slightly, this product would be almost perfect. The other issue that I have with the headset is the non-replaceable battery. The enclosed literature suggests a life of 400 charges. While that translates into a 2 yr life based upon my usage, I find it unacceptable that in today's age of green awareness, to replace a full product because a battery will no longer take / hold a charge

Pros: -3 sets of ear buds for different ear sizes -great sound -controls for volume, play/pause, next/previous track -works well with a good cardio

Cons: -making a call, the sound is a bit hollow hearing people. the people you talk to say you sound great, though.

Overall Review: Use this headset with my moto droid every night when I go for a 4 mile walk/run. Sound doesn't break by keeping my phone in my pocket and running doesn't really move the headset or bounce it around. It's also a decent amount of sweat proof. Pretty comfortable for the hour or so I'm out. I could probably keep the headset on for a couple hours before starting to feel a bit annoyed by them being in my ears. The sound while listening to music is pretty impressive. I have a set of shure e2 earbuds and I actually like the sound of this bluetooth headset better. Plus, it's all wireless. If you're looking for a good headset for an active lifestyle, I'd say pick these up for sure. If you are looking for a headset for just talking to someone on the phone though, I'd find a more simple single-ear solution.

Pros: These headphones work pefectly with the Ipod Touch 1st Generation using the adapter. They have a great sound and the range from Ipod to headphones is very good. The adapter I received was smaller than shown and was black, making it much more convenient! Lasts about 6 hrs. per charge.

Cons: Can't put Ipod in shirt pocket or the headphones won't receive. Needs to be worn on belt or armband, or lay it down and walk around. Supposedly battery only lasts for about 400 charges.

Pros: Works well, the functions (play/pause/rewind/volume/etc) are all properly working with my iTouch. The battery life is pretty good, about 6h worth. Takes maybe an hour or an hour and a half to charge. Range is of about 10 meters. I can leave my iPod in my room and go everywhere in my place without any issues. The headset appears to be sweat/moisture tolerent. I use it when I do cardio, and tried it in the shower twice (kept my head and neck dry though). It still works... so far hehe. I will keep trying to do stupid stuff with them, since I don't really care about breaking them; see the cons.

Cons: The sound isn't very good. First of all, the speakers are not playing very loud, and the isolation is disapointing. So basically, it lacks bass and treble. A proper isolation would solve the bass issue, as I tried to push the headset thighter in my ears and the bass was then efficient. But the treble was still shameful. So, for the bass, I blame the poor isolation (tried all the earbud size, didn't changed anything) and for the treble, it must be Bluetooth's fault. In fact, I'm not really blaming the treble issue as I anticipated it due to the low bitrate of Bluetooth technology. But the bass issue is a real pain. Oh and I forgot, due to the poor isolation, you ear people talk around even at the highest volume. I was expecting something different when I chosed this in-ear headset. Oh and, it's almost impossible to pair with Windows 7. Apparently, W7 doesn't provide standart Bluetooth drivers for the use of headsets, and Motorola didn't provided any driver either.

Overall Review: I wouldn't buy it again, and I wouldn't recommend it to a friend. I will buy another pair of Bluetooth/portable-technology headset in the future, but in a far future. This technology isn't worth it for now. Maybe with Bluetooth 3.0, the bitrate will be higher and the sound quality better, and maybe that companies will provide good quality ear-bud/speakers with their future wireless solutions. But this Motorola S9-HD device isn't satisfying me at all. I'm sorry, I would have better liked providing a good review... This device might satisfy people who don't care about high quality sound and just want a pair of wireless headset. For those of you, this device will be great. It's not so expensive, and for sport, it's doing good. I mean, even if I'm unhappy with my purchase, I'm still using it at the gym and on my bicycle.

Pros: Works great with my iphone 3gs and my ipod nano. You dont need the blue tooth adapter on the iphone because it has blue tooth built in. If you dont turn off the blue tooth on your phone if its around you when you use the blue tooth adapter with another devise it will mess it up. Over all great product!

Cons: It bounces a little bit on my head when i run but it might be because I have an oddly shaped head. :)

Overall Review: Buy this.

Pros: No cord. Lightweight. Reconnect easily if I lose my bluetooth connection (the antenna is on the side or rear so your body can block your phone's signal). Decent sound with the HD enabled. Callers have mentioned hearing room noise from a gym and my 10 year old says he hears feedback, I think he means a hollow echoey sound, not whistling. Good buttons, easy to learn with a positive tactile feel and nice click response. You know where they are and you know when you've actuated them. 3 buttons on each side, easy to find them.

Cons: If I have these turned on then turn on my phone I have to enter the stupid password. Turning on the phone's bluetooth, then the phones, then the music player avoids this. It also avoids the even worse blaring of the phone's speakers while I race to enter a password. What's the password for after the device is paired, anyway? They barely work w my bicycle helmet, they stick out more than buds do so I usually go wired on my bike. The usb/charger cover takes a little care to close, I may put some silicon on it. They seem to lose their charge even if not used. If I don't use them one day, the next day the charge will only last 2 hours so they need to be topped off routinely.

Overall Review: The HD seems to be their bass boost feature which is nice. My phones equalizer (a Nokia 5600 Express Music) won't do what this feature does. I use the larger foamies, with the smaller ones they drop onto the back of my neck instead of hanging in mid air. I think it is a leverage issue, the smaller foamies are a shorter lever so they drop. I would not be happy without the HD/bass boost; it makes the overall sound loss to mp3 compression tolerable. The sack they come with is iffy. I keep them in a plastic sandwich container so they stay safe in my pack. I'd give a 5 if I could adjust the angle of the speakers slightly towards my ear canals and if the tension could be adjusted, sometimes they seem a bit loose but if they were tighter they might ache after a while so....
