I have something similar made by Onkyo which cost a lot more than this but the signal was very flakey - gave this a go and it works brilliantly. Even works with my Mac Mini plugged into the TV, attached to a Time Capsule with all my music on. It's just brilliant.
It will play whatever music type your computer supports as all it does it act as a USB sound card (albeit wireless). The same as wireless headphones.
Fantastic little piece of kit. Plays over 20 metres from PC to amp through some thick walls. Seems to pass whatever your file is Flac ,wav, MP3 . Just plug the dongle ito a USB plug the reciever into your amp with supplied 3.5 to L/R phonos or use your own. Select your music and play, brilliant. Works with Spotify , itunes, VLC, windows media. Sound quality isnt to shabby although it is up to you and whatever you have ripped your files at. Great price! well worth £18.
Having spent the last few weeks uploading all my mum & dads music CD's onto their new Laptop, I was thinking of buying my dad an iPod - bought this instead - this is so much better for them. Just plug n play, USB into Laptop and receiver into HiFi system and go. Also most others selling this product at £60.00 plus. so great value for money @ £34.99, thanks.
