are these ir or rf ? do you lose the signal if someone walks in front of you ? tv ears 3.0 digital

The 3.0 I bought are ir. You need direct line of sight to use some one passing will slightly interfere with signal Warning. Get two ear pieces (receivers ) it's takes like 8 to 10 hours to charge full. And batt only last for 3 to 4 depending on volume when they work the work well my mom is very hearing impaired and these help only wish battery lasted as long A personally I would not buy these again. At costco there is a paire of rf headphones 69dollars 29 hour battery life rechargeable

These will work on Passive 3D TVs. Here is an article explaining the difference. http://reviews.cnet.com/2735-7608_7-1278-3.html

It is IR (Infrared) remote and not RF. You can see the IR LED in the front of the remote. It will not work if you are not in the line of sight. But it is very sensitive and works even at an extreme angle. However, if it is completely blocked by say a door or you are not pointing at the switch then it will not work. Also, a learning remote can apparently learn the code though I have not tried it.

What TV are you trying to use them with? The ty-er3d4su are both Bluetooth and IR and these are IR.

It does not matter. These connect using standard Red/White RCA wires, so as long as your TV has RCA "audio out", itll work. HOWEVER, I did the same & bought them for elderly parents. These are the WORST! Line of site means if you turn your head away from the TV, the sound turns off. They hurt my mothers ears so bad (tight squeeze on the ears), I had to send them back. NOT worth the money...not worth much at all, useless. Stay clear!

Other than the built in dial, I really don't know. I have moved the units location and other radios to be within sight of each other so the signal does not have to go through walls, furniture, etc.

If the comes on and you're not hearing anything, switch channel. If I move out of range of the IR it cuts off. Make sure you're in range.

URC base stations use mono 3.5mm plugs. This 3 Eye IR emitter also uses a mono 3.5mm plug so therefore it should work without any problems.

I bought a cheap Zeikos case off Amazon for this. There is a page somewhere on the Shure support website that will tell you the frequencies that will avoid the TV channels in you area.

Keep ears forward toward tv. I don't have static unless I'm out of range but can walk around freely in tv's area.

We use RF. It works great! I didn't choose IR because it needs line of sight to work!

I know that if you have a plasma tv it will interefere with the sound and create static. I have one, but the static is minimal. Make sure there are no obstuctions in the way and you have a clear line of sight for the infrared sensor to stream a good signal. Also, I use the spdif (optical) cable instead of the white/red. Not sure if this makes a difference or not, but it may be worth a try. Hope it works!!!

I purchased one of those systems, but I returned it. I found the UHF signal to be a lot better. I do not sell them either.

If you have the RF base units installed in both viewing areas, each will pick up RF transmissions from either remote if it is within range. You might try taking one of the RF base units out of one viewing area so that it becomes IR (line of sight) only. You may need to do that in both areas to prevent this "crosstalk"---hope this helps....

Antenna's position is The Key!!! And I use this Antenna: Philips SDV1225T/27 Indoor Passive Antenna http://www.frys.com/product/6640864?site=sr:SEARCH:MAIN_RSLT_PG Sometimes I get almost 90ch but most are foriegn! (Spanish Asian)

they have a blue tooth to IR converter. I've read about it but I can't find it.

Yes, if you have the emitter and plug it into the back of the tv for rf, these need an external emitter but rf is better imo.
