Does this unit work through walls?

No it does not. Earphones have to have an unobstructed way to the transmitter to work.

No it doesn't. Mine is very sensitive and should be in direct alignment otherwise you don't hear anything except a hissing sound. Not happy with this purchase. Also the straps broke right away.

It does not work through walls, although the range is decent in a room it's still line of sight.

Absolutely not, Bluetooth uses radio frequency which will go through walls and such.

It's not so much that the long range versions go farther as it is they work through walls better. We use ours inside and found the long range ones work best.

Absolutely yes. It works great even throught several walls when I am in my house.

Yes, it can work through a few walls. Right now, I have it set up on a desk top computer which is located two complete room over about 60 feet apart. 100% connection strength.

Yes it does. This unit is not battery powered and must be plugged into a wall outlet to function.

No it does not plug into the wall. Tk use this. It needs to be wired into the buildings power.

Well, the unit itself cannot, but the radio signal that it uses will make it through with significant attenuation. The unit was designed to work its best with a line-of-sight signal path, but if you can tolerate a much reduced distance, it will work with obstacles in the way. DON'T count on much signal getting through a metal barrier like aluminum or steel siding.

It didn't work for me to trace through the wall, but it worked when I went to various outlets. I had to put the probe practically IN the outlets, however.

It plugs into the network (or phone) cable on both ends, so it doesn't matter if there is a wall in the middle, as long as it's a complete cable from end to end. Length-wise, I've used it for cable runs of about around 75-100 feet and it worked fine. It's just testing for continuity on each of the wires in the cable in sequence, nothing more, nothing less.

The remote uses a radio frequency to control the unit. It works quite well through walls and doors.

Yes it does. But it's only a USB chord, you need to get an adapter for the wall separately.

No it doesn't. We simply use the racks to push out the wall. Good quality unit!

it goes through walls for me. I live in a dorm right now and whenever I'm at my friend's next door, I would have to disconnect so we can hear from my computer speakers again. It also overrides headphone and hdmi aux.

No, the plug prongs flip outwards on the back so you can plug the whole unit into the wall. It also has a regular usb port on the side. I've never used it, but it's there if I figure out something I need it for. This is a GREAT little item

Yes, the device transmits a radio signal that will go through most walls. The receiver for these signals emits infared light pulses just like the remotes that came with your units in another room, so this remote must be placed so the light it emits is seen by the sensor on the units being controlled.
