What is the opinion of Reddit about the
Koss BT221i Wireless Bluetooth Ear Clips, In-Line Microphone, Volume Control and Touch Remote, Sweat Resistant, Black?

How about these? They have a cord connecting to each other, but they’re Bluetooth and would be mostly unobtrusive.

Dunno if this is too late, but I’ve actually just came across a wireless version of the KSC75 (well, almost).

Check out the Koss BT221i, though the reviews on Amazon aren’t overly enthusiastic. Relatively cheap though.

I found this one looking for a similar thing for a friend recently:

Can’t comment on the SQ though.
