Bluetooth receivers - inexpensive

[pboser]

Does anybody have experience with any cheap Bluetooth receivers for audio?  My idea is for my kids to use them with t-amps in their room (or dorm room) - since the source is almost always iPhone or MacBook Pro, I know they'll like eliminating the wired connection.

I'm looking at a few options, all around $20, and wondering if anybody has any experience with them and observations about sound quality.

The ones I'm looking at are these:

Obligatory Bottlehead relevance - 1)my daughter's boyfriend just bought her a "record player" and she's looking to raid my record collection, so maybe we can develop some bottle interest; and 2) my son is interested in a kit - maybe a quickie (with headphone connversion) is in our summer plans.

Thanks in advance,
Pete

My experience is that Bluetooth receivers offer convenience but often lack in fidelity. That said, the quality of sound seems to be all over the place depending on the manufacturer. I also found that you need to spend a little more to get decent performance. As I recall the $35 to $50 range seemed to be the sweet spot. I liked the Miccus receiver best at the time when I was doing comparisons. Mind you that was over a year ago. Ultimately I bought a decent interconnect cable and gave up on the Bluetooth idea. YMMV.

I recommend sparkfun.com they have lots of cool stuff that you might find useful. (I have no association with them, other than ordering from them a few times)
