Great for WiFi, not so much for BlueTooth
582217
I built a desktop computer and put this card in it.  WiFi works great.  Don't forget to add an antenna or you're have to be about 10 feet from the router to get wifi.  My problem with this card though is that the bluetooth has never worked.  Windows 8.1 64 bit and no matter what version of the driver I run, or how many times I start fresh and reinstall.  I've just given up and bought a new bluetooth adapter.

Pairing is elegant with a courteous confirmation tone.  Sound quality via AAC is excellent.  However, the range is terribly limited.  It probably works a long time if the phone is sitting inches away.  But, for my purposes, I was looking for something to use in my home gym.  I soon realized that it has a max range of about 20'.  When body mass blocks the signal, such as when laying on floor with knees up, that range diminishes to about 3'.  Also, because I am using both bluetooth and wifi at the same time, battery life is affected.  I think I will return this and get an older Airplay with an analog out.

Update: Apparently, my drop-out issue is about more than just range.  I am currently experiencing the same one-or-two-song playback before the thing stops.  The bluetooth menu on my iPhone still says it's connected.  The blue light on the unit remains steady, just no music!  I tried finding a firmware update on the Xtrememac website but no luck.  Will be returning it.  Also, no option for AC power.  As a matter of convenience, I like something I can plug into a switched receptacle so that I can just flip one switch to turn everything on.  For audiophiles, I would highly recommend an Apple TV.  It has the range of wifi and plays back at up to true uncompressed WAV quality straight off Apple devices, outputting up to 48 kHz via optical.  I use this on my good system and it is so good it makes me drool.  But it costs $100 and does not support bluetooth.  For the gym, I want bluetooth so users of other brand phones can use it if they want.

I purchased this Bluetooth transmitter to work with a set of wireless headphones. The transmitter pairs easily with the headphones, but there is significant latency (delay) in the signal. This makes the transmitter/headphone setup unusable for many applications.
If delay in the audio is not a problem for your application, then this is a fine device.

Good thing i only got this for the wifi, because with bluetooth connected the wifi drops significantly in strength. I tried the drivers on the cd, the newest drivers on the Intel website, and i even tried the drivers windows downloaded. Non of them fixed this issue. Without the bluetooth it works great and never drops connection. Of you want Bluetooth, get a seperate device. These 2 in 1 devices are just asking for issues

I've been using it for a while now and it does what it is made to do: play music wireless from a device through Bluetooth. Sound quality is great so far, can't notice any difference in sound quality versus when I plug my phone directly to my speakers. I bought this mainly to use in my car since it allows for you to answer your phone through Bluetooth. Unfortunately, when I try to play music with it in my car, the sound is spotty as if the phone has not made a clear connection with the receiver (despite having the phone directly next to the receiver). Also when a call is answered, you cannot hear the person talking unless you turn your car speaker way up (this may just be a problem with my car).

This is a great product, but really only if you don't have Bluetooth. It's one of those situations where you can't get a cheap radio that has a speaker (they all rely on earbuds now). Plus, cheap, small radios don't have Bluetooth, either. So, I simply use the headphone jack of a non-Bluetooth radio as an external speaker. Works well in that regard. It's also kind of big to be hanging on the top tube. Plus, it doesn't help that the velcro straps are all of varying lengths so you can't get it tight on the top tube. But, if you have a rear rack, well, it works fine back there (although then you can't see the smartphone, either). All-in-all, it works well for me to use the speaker with a cheap radio, carry it on the rear rack,  and I don't lug along my smartphone.

connects easy, everyone in our household can use it.
just the transmitting/receiving distance between bluetooth device and receiver could be better. i get only 5m without drop outs. (might be because our environment in the 2.4ghz area is quite busy)

The product works as intended. The need for an internal USB port (which is different from an external USB port) for Bluetooth wasn't an issue, as it was completely unused. The Bluetooth works great, and I had no connectivity issues. The device also comes with an antenna which sticks to magnetic computer cases. This is used to connect to Wi-Fi. I did sometimes have my Wi-Fi cut in and out, but it only happened for about a day a week after I got it, so I think it was just my internet being weird.  If you need a decent Wi-Fi/Bluetooth card for a custom computer build, I would definitely recommend this.

The Bluetooth capability is amazing, it has paired with my phone, tablet and laptop with no issue.  However, it is pretty slow to print and scan, that's why the 3 stars.

Great sound, but without an option to play non-spotify media (like youtube) over wifi is a deal breaker for me. You can do this via bluetooth of course, but it means I can only play from one of my many devices around the house.

I like the size and feel of this wireless Bluetooth, but it does not transmit as far as the last Plantronics Bluetooth, despite it's claim. Wishing there was more reach

Ive had this for a few months now, and Id say it works pretty good.  Decent sound, easy pairing, and simple controls.  My only complaint is that the range on the Bluetooth is pretty short.

The sound is good, but the bluetooth connectivity is not stable.

I love the convenience of having a great-sounding speaker that taps directly into my Wi-Fi network without me having to stream music from my mobile devices via Bluetooth. I have some great Bluetooth speakers that do that well, but it can be an inconvenience (and frustrating when mobile alerts also get broadcast to the speaker). I like that I can set up to 6 one-touch presets that will start streaming favorite playlists or stations from music services like Spotify and Pandora. The system currently supports Spotify, Pandora, iHeartRadio, Deezer, and the generically-named "Internet Radio" (which seems to have a decent selection of stations, including local radio stations). You can also supposedly tap into your personal network-based music collection, but I have yet to set that up. Personally, I'm disappointed that services like Amazon Music (both Prime and my personal cloud-based music collection) and Audible aren't supported, at least not yet. Yes, I can play them through the SoundTouch via Bluetooth from my mobile app, but that isn't any different from my other Bluetooth speakers that sound just as good and cost less. Nonetheless, this seems like a great speaker and, if the system works as advertised, part of a potentially bigger music system that can stream music through an entire home simultaneously. I'd love to hear how this holds up against a comparable speaker from the Sonos system.

The sound quality is great and the web user interface is fairly intuitive with useful functions.  What isn't great is that you can't broadcast music using bluetooth.  For instance, if you want to play music from a website such as YouTube or an online radio and broadcast it via Sonos, you can't.

Works great but may get some static if nearby a lot of WIFI interference.

bluetooth has some lag though (I'm using an S8 so plenty of hardware speed). if using with an android device for gaming, assume that the tiniest delay will frustrate at times
