I have a pair of S9 HD's and they sound fine with my iPhone. Sound is so subjective thing I have seen postings that a pair of headphones sound great and my pair sound would sound bad to me. I use the bluetooth reciever on the iPhone with no adaptor.

I have the first gen S9 and the only problem I have is when on the phone people say they get a lot of background noise... so I pretty much just use it at home on the PS3. other than that I have no problems with it.

Is music (or sound from video) very clear and uninterrupted (no pops or hiss)?

I'm trying to get an RMA from the vendor to see if a new headset will fix the problems I've found with this one.

Both video and music sound fine. An background noise is picked up be the mic more. I have a jawbone headset and my wife can tell when I use the S9's.But the sound for me is much better than the Jawbone which has a low sound level. Several co workers have the S9 and love it. The reason I purchased the S9.

Are you sure you had it synced with the A2DP (stereo) and not the standard Headset profile. I've done that before, making the audio sound like a cell phone connection.

i get no pops or hiss when i use it with my ps3 or cell

Okay, I've come to the conclusion that Morotola has designed this stereo bluetooth headset to only work with cell phones and not with laptops/netbooks. I've finally received my second headset and I can't even get it to play sound from the netbook (though this might be an issue with the Win7 BT drivers).

I'm really disappointed that Motorola would design a set of headphones that would only work with phones and not with general audio devices (like netbooks).

Does anyone know of a pair of bluetooth headphones that will work with a netbook?

TIA

I have the non-HD S9's, and I have them paired to my desktop via a USB Bluetooth dongle. The audio quality certainly isn't hi-fi, but it's still pretty good for music, movies, etc.

I honestly think it's the Bluetooth drivers you're using. I have the Toshiba Bluetooth Stack v5.10.08 installed on my Windows 7 machine, and I have no problems with my S9 both in terms of functionality and audio quality. It also has the AVRCP installed, so I can control iTunes and Winamp remotely.

I just got off of the tech support chat with Motorola. They're telling me that their S9-HD headset is compatible with any other Bluetooth device that supports A2DP and AVRCP. Now all I have to do is check both my Iogear BT adapter and the Win 7 BT drivers to see if both of those are compatible with "A2DP and AVRCP".

Why is it that no technology is simple and easy to use nowadays?

I've had mine since they came out and i love mine. No sound issues at all with my iPhone.

I have had no problems with my headphones. Maybe the adapter is the problem. I use it with the iPod adaptor and with my blackberry.

Alright i have one question for you, is the light flashing blue or green when its playing audio from your machine? if its blue thats your problem. Blue means that you are connecting using the Bluetooth mono headset profile which which uses super heavy compression and is really only meant for phone calls.

Now what you want is for it to be flashing green meaning that your connecting over the higher quality stereo A2DP Bluetooth profile. Now what alot of people don't realize is that the Bluetooth implementation in windows (any version, even 7) is incomplete. It only supports a hand full of the most used profiles like human interface device, used for things like mice and keyboards, and the headset protocol for crappy mono audio and taking input from a mic. Windows 7 (and thus all previous versions of windows) has not support for A2DP out of the box. Microsoft expects the Bluetooth adapter manufacturer to provide there own Bluetooth stack and implement the rest of the profiles.

tl;dr: It's probably not the headphones, it's Microsoft's fault for shipping windows with a bare bones half-assed Bluetooth stack instead of a complete one. Try connecting to another a2dp capable device like a mac or smartphone.

The device sounds good for me only when connected to a source on the max volume possible, otherwise you'll hear a lot of noise. Set your pc to an 80% and then control the volume on the headset, maybe that can help.

I don't know if you still need help here, but since I had the same problem and was able to fix it with ease I thought I would let you know.

I have an Iogear USB 2.0 adapter as well and am on WIndows Vista Ultimate. I open the Bluetooth control panel >> Add the headeset >> Right click on the headset and go to properties >> Services >> Uncheck all but Audio sink and Headset.

That's all it took and now I get great sound; no hissing or popping anymore.
