My Yamaha receiver would shut off when you turned it up past -27. It would say check speaker wires. Purchased these and its the best money ive ever spent. Now i can actually use my polk speakers and surround sound system after 4 years. Very Satisfied.

Great receiver, easy set up, PLENTY on inputs, and even has a damn router (that i'll never use). Word to the wise, the ONLY beef i had about this receiver is my Sub would not work. Through hours of tweaking settings and searching the web i found my problem deep in the online instructions. When you select "Large" speakers in the set up menu it automatically disables your external sub woofer and prefers the built in ones in the Large speakers. VERY ANNOYING and nothing i did reversed it when set to large. Other than that great system.

System suddenly shutoff while playing music from the USB front port with an electronic burning smell. It will turn on for 1-3 seconds and shut off now. This receiver just went from a 4 to a 1.

Great value on a nice receiver.  However, as best I can tell, I can't play speakers A and B at the same time.  Could this be so???

Works great! Solved my issue with my rear surround sound speakers not working. Now, they work as they used to, great!

First one we ordered directly from Amazon.com was defective: when more than one speaker was selected, sound from the left speaker (in all connected rooms) would fade out.  Switch it back to just one speaker (at a time) selected and both speakers would finally come in.  Amazon replaced it and the replacement works perfectly now, thank you!  It's nice to have selectable sound coming from all 4 rooms now, powered by our Onkyo receiver which was only capable of powering up to 3 rooms by itself.  Sound quality sounds good so far!

System continues to turn off once sound gets too loud, then I have to unplug from surge protector and reinsert in order for it to work

I bought these used for $40. I'm using them on an onkyo 80 watts, these things are awesome!

Speakers have constant feedback, have a different plugged into same ports to check to see if it was something else causing it, but no just the speakers. Likely to return them.

Your Home receiver has one HDMI out probably.  Most likely you are running your HDMI cable from here to a TV that may be several feet away. If you break your HDMI out you are sunk.  You went from having a convenient way to connect multiple video sources, and display them on your TV, to having an old fashioned receiver thats good for audio and component inputs.

I had this exact scenario play out.  My receiver's HDMI out broke when sliding it back in place.  Any other part wouldn't have been an issue.  I installed these on the replacement receiver, and could instantly tell there was a significant difference in the tension placed on the plug. I would advise anyone installing a new receiver to purchase these for your HDMI ports, or at least your HDMI out.

Absolutely a little gem.  So, my specific use for this product is probably not a common thing, but I thought I'd describe it in case someone else has the problem too.  The ground loop noise problem was happening between a PC sound card input and a two-way radio being used as a receiver.  We are using the audio from this radio to feed the PC to provide audio from our ham radio group's repeater to Broadcastify.  Prior to using this device, there was this constant "whine".  It sounds similar to the whine you hear on a commercial airliner when you plug your headphones in - that high frequency alternator whine.  The instant we put this inline between the PC and the radio, the problem went away.
I highly recommend this for similar ground loop issues.  It will probably solve your problem!

In hope that this might be of some help to those who are buying or using these headphones, let me try to describe my own experience:

At the very first use the plastic holder of the PCB inside the transmitter case was broken, so I couldn't plug into the power connector. Upon opening the case I found VERY POOR SOLDERING and very fragile DC connector which probably wouldn't last for any reasonable time anyway. I fixed the holder with a superglue and DC connector fixed by re-soldering.

When transmitter is charged from DC source, transmitter signal level in "Wireless Headphone" function  is too low, much lower than of FM radio, but what makes this option unusable is an EXTREME HUM! I tried to use several power adapters (conventional or USB type) obtaining somewhat different results, but these noises are always absolutely unacceptable!!! However, when transmitter is charged from internal batteries, this problem is not present and sound is good enough! I suppose that the cause is a critical lack of a proper filtering of EMI noises coming from power adapter, what means that DC power option here is generally unavailable and that's a very important drawback, not mentioned at all anywhere in product descriptions.

The next, even bigger problem in my case was deathly interference with one of TV channels on my cable TV, so that the complete TV channel was totally distorted (sound and picture)! Ok, probably it's not possible to absolutely prevent such a conflict, so it couldn't be complaint to the device, but perhaps this comment might be of some help to somebody in resolving the problem. I have resolved that problem in the following way: firstly I little bit lowered the transmitting frequency by slightly NARROWING the transmitter coil, just until the interference disappeared from the TV screen (I guess the modified frequency now is set to about 87.2 instead of originally 87.5 MHz). However, then I had also to extend the lower end of receiver's (headset's) frequency range, by little bit narrowing the coil on the headset PCB, so that the receiver can reach the new modified transmitting frequency.

As a new surprise and an additional problem I found that in the wireless earphone mode the stereo sound is NOT SUPPORTED AT ALL! Moreover, the sound is not even channels-combined (mixed) mono, but what is received is just the left stereo channel, while the right stereo channel is completely lost!!! However, for listening to TV, mobil-phone or similar, that couldn't be acceptable; for example, if you are listening to a music, you are probably going to miss a significant part of the music tones!!! Nevertheless, the product specification clearly states that product IS supporting the "FULL-CHANNEL TV SOUND"! Also, the transmitter's pictures show stereo type audio-in jack, what implies that support for stereo transmission is assumed, and nowhere in the specification this is explicitly denied!!!

The size of headphone's ear-pads and headband I found really TOO SMALL! Even when the headband frame extended to maximum, all this seems like it was designed for children. I adjusted a little bit the frame shape by heating it with a hair dryer, but it didn't make a big difference.

At the end, I use these headphones only to listen to TV news or debates, and even that is not too often. Of course, I understand that these headphones are really cheap, but this is not the answer to my huge disappointment because of a substantial discrepancy between the real product features and expectations based upon published specifications. Needless to say: if I knew all i know now, I'd never buy this product! However, DEPENDING ON YOUR NEEDS AND EXPECTATIONS, these headphones might be a satisfying product, but you have to know exactly what you are asking for and what you'll get with these headphones!

The analog audio started outputting some noise that has gotten worse over time. Fortunately I can use the optical digital output, where this problem is not present, although it adds another device to the chain.

UPDATE TO INTERMITTENT SHUTDOWN :  Adding a laptop cooling fan on top of the unit to pull air out did the trick; can now play at all volumes and the unit doesn't shut down. Doesn't change my rating, but I'm glad I don't need to pay for a repair. The cooling fan plugs into the USB port on the front of the receiver; the port is ALWAYS powered, so either leave the fan on all the time or manually unplug it.

ORIGINAL REVIEW:  Loved this receiver while it worked, but it developed some intermittent shotdowns, most likely due to overheating.  This occured even at moderate audio levels and plenty of space for ventilation. Have seen some folks use laptop cooling fans to address this issue with other models/brands. If it works I'll update the review.

Pretty disappointing and not worth a repair bill

My KRK RKT6 way too sensitive to any power junk and make that noise y'all know. I tried a ton of different filters. Mixed power outlets. Reinstalled drivers and played around with drivers and ac settings. I even bought used amp to connect to pc via optical cable and get rid of that crazy annoying noise. Nothing helped except that simple device. LOVE IT!! Thanks a lot! I hope it'll work for you as it does for me.

My wife was using an old set that we got from a family member and she loved them.  So we decided to buy two new sets of the exact model for her to use in two different rooms.  Unfortunately both of the new sets have a loud buzzing and interference to the extent that they cannot be used and will be returned.  In an attempt to root cause the interference source on the new sets I switched out new and old components using the base, the headphones, batteries and power cord.  Turns out that the new power cords are the source of the problem.  Both of the new sets sound fine with the old power cord and the old set that always worked fine had the loud buzzing with the either of the new power cords.  Now that my mini Red X study solved the problem for Audiovox I hope they soon resolve this issue!

Yamaha:  Please help, I don't know how else to contact you and get assistance with this problem.

The receiver is very powerful and easy to use. Hook up was so easy I did not require any reference to the manual.

However, about 2-3 weeks into usage, my left rear surround sound (only while on HDMI5) goes out intermittently; seemingly tied to receiver on-time (i.e. heat?).  I have my DVD player hooked up to HDMI1. I have my DirecTV hooked up to my HDMI5. I use DirecTV to play music channels.  I turn the TV off and simply play the music through the receiver.  However, HDMI left -rear surround sound always goes out about 1 hour into play; ruining the "surround sound" experience.

I can switch over to HDMI 1, turn on the TV and magically, surround sound returns to the left-rear speaker.  This is what confirms it is not the speaker, not the wire, not the connections.  I'd like to return the receiver for diagnostic work and get a replacement, I am THAT certain that it is a faulty channel baked into the receiver.

It says check sp wires even after replace the wire and make sure they were all connected right ..
Everytime I  turn the volume on the receiver turns off
