Does anyone have a recommendation for a Bluetooth transmitter with a line level stereo input? I have a customer who put his treadmill to far from his ceiling speakers and now to hear the speakers over the treadmill he has to crank the speakers. I am able to get a line level signal to with in 10' of the treadmill. A Bluetooth transmitter would work well and he could use any Bluetooth head set that is sweat proof.

I can do a Google search but I just want some first hand recommendations, if anyone has any.

We have used the Miccus Blubridge unit with good results. The application we were using it for was in a dentist office and from the TV's to chairs was only about 10 feet. We did test it in our shop and with line of sight to some Sony headphones, it worked about 30 feet until it started cutting in and out. It runs on rechargable battery that charges via USB but we just got USB power supplies and left them plugged in permanently. I think they can be had for around $40.

I have used these before.

How about a transmitter/receiver pair that can work with standard wired earbuds or headphones?

I've used these a few times for home gyms and the nice thing is that the customer doesn't have to worry about keeping headphones charged.  Both the transmitter & receiver are powered and the reciever can even be powered from a CSAFE port if his treadmill has one.

 Xantech makes one.

Thanks guys, I was looking at the Sony one. I am looking for a transmitter and the Xantech and the Miccus are both receivers.

The Miccus unit is a transmitter.
