Has anyone tried the SHB5850? It looks like a Bluetooth version of the 3900/3905. It costs around 80$ in Best Buy Canada but it's often on sale for 40$ (around 31$ US).
I've had the 5850s for awhile, and got the 3905s this week. Yes, I am reasonably certain they are the same thing, the former bluetooth, the latter wired. I can't be ABSOLUTELY certain because the 5850s don't have a wired option for comparison, but they are identical in size/shape, and very similar in sound signature. The DAC on the 5850 seems to give them a rather large bass boost, but I still like them quite a bit, as a cheap wireless option that sounds pretty good.
The wired 3905 is soo much more detailed, but both have great separation and relatively nice soundstages. Really, the 5850 does a fine job with the signal it receives. The 3905 just has access to much better signals. I am looking forward to receiving my Etymotic HF5s later this week to compare =)
