Many A2DP adapters I've used present nagging, persistent low-level high-frequency digital noise when not actively in use. Is this one "clean"?

it was while it worked with my pioneer. the only noise was at high volume on my cd player with my phone paused. it worked for about 6 months. tried on a new cord, and jaw bone dock. wont work anymore

I notice very little noise, if any when walking around. Microphonics is an issue though, under abnormal circumstances. Running or fumbling around for something in your pockets for instance. Personally, I've never been annoyed by or have noticed this particular issue under normal circumstances.

Er, Would you please describe it more clearly? It always working with buzzing sound, or sometimes, or frequently? How your headphone works without amplifier, buzzing or not? Have you ever tried to change another adapter?

I just installed the v1.4 beta driver on my 64-bit Windows 8.1 laptop, and playback of 24-bit, 192 kHz files is working beautifully (I'm currently listening to Kind of Blue from HDTracks). I have a concert to record this Thursday, so hopefully the A-to-D side is working well also. I use external mic pre-amps and just run balanced "Hi-Z" into the E-MU for recording, so I don't anticipate any problems there.

Have not noticed any interference. However, my audio is balanced or digital.

No that is not normal. I have had that happen to two different M-Audio USB interfaces that I've owned, both of them different models. With both devices, they failed to work completely, and one of them even emitted a loud clicking noise. It is broken. While this scenario is not how the device is supposed to operate, it is normal for M-Audio devices as they break in this manner often.

My kids got me these spealers last Christmas (2013) and I long ago stopped using them. There is a loud background hiss, and popping noises on the bass unless turned down really soft. The bluetooth worked fine with my 5-year-old HP laptop, but really that is irrelevant under the circumstances.

Standard transmission rate for a Bluetooth 2.1 compatible device. See this article... http://soundexpert.org/news/-/blogs/bluetooth-audio-quality-a2dp. The audio quality has more to do with source than this device.It is good enough for my liking. The most annoying part is a constant clicking I hear, but I believe that is noise interference issue that may or may not be due to the Mediabridge itself.

It should just activate when you plug it in. That's assuming your source device supports A2DP (stereo Bluetooth). I did have a problem with each one I owned though... The connection oxidizes. It gets a green "rust" on it and has trouble making a good connection. You can scrape the connectors with a needle and it works again until the buildup returns. That's just a normal issue with metal contacts that carry low voltage... they oxidize. It's probably why they discontinued this model... sadly. It's about the best form factor I've found for stereo and one of the best headsets for music because of the AVRCP feature (FF, Rewind, and pause). I have yet to find another one that has that feature and is an "in the ear" device.

I get the same thing. Was considering returning the unit because of the aux input noise.

I just bought it. It's the Normal wave. A2DP protocol is not correct for music streaming. I use a app to listen to music using this device.

No not really, i had the same problem with this, there might be a solution somewhere, but I haven't found any. I just use an external audio recorder with Xlr inputs, I don't use these adapters anymore

There is a CD with a preview of something I'd never use; gladly I found no need to use it. With Windows 7 (both x86 and x64) I had to go into the "add driver" area in Windows Device Manager for this device and choose "Generic Bluetooth Adapter" from the list of drivers. This comes built-in in Windows, but it doesn't get automatically matched up with this device. Once selected, things worked! The A2DP profile is not part of the default install, but automatically installed once paired to my headphones.

I have had this unit for almost a year in live application and have not experienced any unusual noise or hiss. I am sure if the gain structure is wrong any unit could have the potential for noise. hope that's what you wanted to hear

I agree with 2ownlife's answer. My Soundlink 2,unit made that blip noise from day 1 right out of the box when I plugged it in with the OEM charger. I wouldn't worry about it as I believe it is normal operation.

That's the theory, Christopher - unfortunately I can't tell you if this is one of the ones I bought all around the same time which did not make proper contact so I finally gave up on the idea. They all worked but sometimes at reduced volume and often I had to wiggle the contacts to keep them working. As I say, though, I have no idea if this specific adapter was among them.

I am experiencing the same issue now. i searched the web and it looks like this is a common issue. So what now? trash it and buy the BDP-S570? I need some $$$ back from Sony at least.
