I have had this headset about 9 months. At first the sound was great, it was comfortable, affordable, and seemed durable. After about 4 months the sound started to falter. I know it's something to do with the wiring but I'm not sure what it is. It would play the background sounds but not voices or bass. If I wiggled the wires a bit it usually helped, but they had to stay in a perfect position usually by shoving the wire into the actual ear piece. It's just gotten worse since then and I finally cannot hear the voice/bass at all, only background sounds. I have had no issues with any other part of this set however. And they lasted longer than the Koss headset I had purchased. I am not sure I'd recommend these. I wish there was a longer manufacturing warranty, or Yapster would make the wiring more stable, because other than the wiring, it's a great headset.

So I purchased this pretty much because it was so gosh darn cheap and for what I paid for it I suppose it upheld to expectations. I used it on and off for about 5 months and over the last month it started to make a nice crackle sound whenever it was plugged in. Eventually it stopped working from what I assume is a bad soldering job on the internals.

So if you want a good few months of use go ahead and get it, but I am now looking for a better made unit.

I noticed when I was listening to music that they were getting hot and I had just turned them on when I took them off to feel it they started to pop and they basicly exploded

After 3 years (and after the warranty period) the sub started to crackle and pop. There would be a large thumping noise (like a heartbeat) even when the receiver was off and sending no signal. Polk customer service was excellent in diagnosing it as a bad amplifier. Since it was after the warranty a replacement amp was $120

Ok at first, it sounded great! But now, but it hasn't been a year, the sound zooms in and out! I don't recommend this!

When it works it sounds great--muscular and warm. The amp also comes with fasteners so you can strap it to your phone (or whatever) which is a nice touch. It even feels reassuringly hefty. However, on Day 2 the weird sporadic clicks turned into a full-volume scream, causing me to rip the headphones off, pack it up and send it back. Get rid of those quality issues and this would be a great product.

I would guys. Look somewhere else. If you read reviews then you already know the volume issues. I tried a lot of different ways to fix it but im stuck with a speaker i can only use when extreme loudness is appropriate. Also volume crackling occure after a dozen uses.

This mic worked great for a while. I bought this in April 2016, and I use it for podcast recording. Just this past week during a recording session, my audio was corrupted by an electrical whine. Ive tried using a different USB cable, USB port, and even a different computer, and the whine is still there. Something is defective and Im very disappointed.

At first I thought it sounded OK, and that the little notch where the cable goes into the device was clever.  Especially since my previous device died like that, frayed wire from the constant in and out of my car's tape deck.  But I've had it for a few months and it has developed an annoying, super loud, high pitched whirring noise, more like racket.  I have to get the volume up to 7 or 8 of 10 in the stereo to be listen to the music over the whirring.

The sound is great, but after a while it became messed up and distorted. However I know others who have had no problems with it.

I have been using this sound bar with moderate use for almost 3 months now. Never have i had it blasting or very loud since i live in a small apartment building and rather not disrupt my neighbors. Unfortunately what others have said here is very true the sound bars starts to produce a cracking noise which is very annoying from one of the right speakers. fortunately I bought the extra warranty with this item and will see what they can do for me. I will update this review once I have been contacted with more information.

This sub is awesome when it worked, bought it in September and it stopped working properly in December of the same year.  It just stopped being as loud like there is something wrong with the built in amp, it's turned up all the way and you can barely hear it.  Back when it was still working, half way volume on the sub would shake the house..  Very disappointed in the quality of the amplifier.

Bought speakers 10 months ago and things have been perfect. However about 8 months in 1 speaker started having excessive crackling and I have no idea what it is from. The crackle makes listening to music unbearable. Before this happened the speakers were easily 5 stars... but apparently Amazon doesnt have a 1 or 2 year warranty on these guys for me to return them which is why I am giving 1 stars: product had a pitiful longevity.

I was very happy with this speaker that I purchased about 6 weeks ago but now the speaker has a buzz sound as if the speaker is blown. I use this at work so the volume is never up too loud. I'm going to see how the seller treats the issue

I loved this receiver but soon after buying it a crackle showed up in the speakers and I couldn't figure out why until last night...

It was interference from the FM antenna!  If you have this receiver and there is a crackle in the speakers in any of it's modes, it is because the FM antenna interferes with the speaker signal.  Unplug the antenna and the crackle will go away, plug it back in whenever you want to listen to the radio.  It's that simple.
