Is there a break in period for these? The ones i recieved are not functioning correctly.

No break in period. It's either it works or not. Sometimes it's better to change the one's before the catalyst converter and the one's after it by the exhaust

No, there is no "break-in" period. I recommend making sure that the fault code(s) have been reset (if any to begin with) and then unplug them again and reconnect. Special note that it is a very snug fit. Make SURE you have them plugged in completely.

No, they should work properly, depending on your car you may need to have the check or service engine light reset.

Just wanted to pass along that Amazon took back the opened package. Others I've listen to didn't sound anything like the crappy ones I received.Amazon has first rate customer service. I'm going to try a different pair from here. Any suggestions?

I don't know, but so far, after a couple months, mine are good. Maybe your set is defective. Try for an exchange.

Yes, they work fine. Are you not being heard? Or are you the one who can't hear? Might be your controller? Test them on another controller.if not, contact the seller they might be faulty. Thats bad luck...

I ended up returning them (not Amazon) and am waiting to see if they'll send me replacements. I called Coby's tech support and it was a hired out firm. They didn't know the answer either and couldn't help me.

I would exchange them through Amazon, mine have been working great since the purchase.

That's what Im afraid of. Were they still under warranty and did you try to return? thx!!

Hi. I have not used them enough to tell. Also, I cannot tell even if they are working. I need info also or will return them sorry. Michael

Yeah it sounds defective. I would suggest calling Amazon to see if you can get an exchange.

Mine have been working perfectly well. I agree with the other post and try to contact the manufacturer. Amazon can probably help with that.

I just checked mine and there seems to be a tiny bit of stretch. Given the price and how well they work, I would give them a whirl. Good luck.

They may be defective. Ive owned several sets and haven't had that problem.

I have not experienced that problem. I'm sorry I cannot help you. You might check you connections push the plugs in and out a couple of times as sometimes dirt or some form of corrosion forms on the connections. If not send them back an get another pair.

I've had the same issue. I think they are temperature sensitive, which is the same as being faulty to me.

You got a bad pair. I don't have this problem with the pair I bought last year. If you can return it or get ir replaced, I'd suggest you do that.

I am having the same issue, did someone help you with this issue or did you just return them?

We had that happen, but we can't remember exactly what the issue was. My wife thinks that she shut them off and turned them back on to correct it. Ours broke within four months. It has been a while since we used them.
