Waste of money: obscene amount of static, and mine was a horrible defect.

Complete waste of money. My brother and I each got a set and we're both disappointed. In short: way too much static, mine was a mutant where the microphone was located IN THE EARPHONE, I could not hear my brother speak in the voice chat (yet game music worked), and volume control was a mess. Im going to note right now that neither of us are serious gamers and we bought our sets from Fry's, not Amazon (and also that I'm a mediocre review writer, haha).

STATIC: The main reason I hate these is because, when used with adapter's* USB and headphone jacks, there was a constant high pitched static that would change depending on if you moved your mouse or opened a screen on your computer. It was like the USB was amplifying the sound too much, and we were hearing the electric currents inside the actual computer. Both of us have wireless mice, which we though may have been causing interference, but we unplugged them and turned them off and the static was still going strong. It was loud and for the $40+ we spent on these, its totally unacceptable. When used with the headset's headphone jack (and not the adapter), there was no static.

DEFECTIVE: Also, my set was F-ed up very badly. The physical microphone stem looked fine, but I couldn't get my computer to pick up anything when I spoke. After a bunch of tests, I noticed it detected sound when I spoke INTO THE LEFT EAR PHONE PIECE, where the sound should have been coming OUT. Sure enough, thats where the mic was. For the entire test chat, I has to speak into the earphone.

Sound did play from the earphone pieces, but half of the time it only wanted to play through one- like it was half broken. When my brother and I tested the voice chat, I could hear game music but not him speaking. It actually took a separate pair of headphones to be able to hear the game AND my brother.

Microphone and sound BS aside, this headset was just plain tricky to set up- it took me too long to figure out what settings to give it in the Control Panel and what volumes dials to use. My brothers was a little easier, probably because his set wasn't defective.

Sound Quality: When I used it with just the plain headphone jack from the headphones (not with the adapter box), the sound was decent enough but way more crisp clear highs than bass, which was pretty pathetic (I like an obscene amount of bass, though). Theres no sound privacy either, my brother said he could hear my music from 7 feet away. On one plus side, I couldn't hear myself talk when the music was up loud.

I cant really rate the sound quality of the microphone purely because Im not familiar with headsets, but my brothers voice sounded pretty good, except when he said s sounds, you would hear pixilation so-to-speak, like lower quality sound.

Build/Comfort: They feel alright, but Id be nervous about the folding joints snapping if you cranked them to hard. Theyre comfortable too. The red underside of the upper band is the softest leather stuff youll probably ever feel. Please don't let that be a reason to want to buy this thing, though. The entire headset and the adapter box is coated with what feels like a thin layer of silicone, or something like it.

*This thing comes with an adapter box that has jacks and volume controls for Xbox and Play Station use, as well as a plain headphone jack and USB cable for the computer. The actual headphones have just a normal headphone jack, which can connect into the adapter box. We used them only on our PCs, connected with the provided adapter box and USB/headphone jack cables that came out of it. Id have taken pictures, but these things are already repackaged and ready to be returned to the Frys from whence they came.

This converter is very cheaply made and mass-produced in China. It worked well enough for me to get TV audio (new LG LED television) through my external speakers, but all TV and movie sound was accompanied by a soft, constantly crackling of static. My other input devices (radio tuner, CD player) produce no static whatsoever, so the problem clearly is in this converter.

Lesson learned. I'm returning this item and will spend a few dollars more to get a quality product.

Don't buy this!  I have so much static interference and I'm only 10 feet away.  I have moved it, changed channels and made adjustments, still the same. I've connected it directly to the cable box and to the TV but no difference.  Too bad I didn't use it enough to send it back on the Amazon warranty.  Good luck finding any info on the Manufacturers warranty...no documentation or info about that. Looks to me to be a 90 Day piece of crap and it cost $ 100.  Never again!

Too much static in the headset and speaker. I quit using them after one call.

Got my headset and noticed there was static in one ear. I thought the issue was due to interference with other electronics, but quickly realized that wasn't the issue. The static will go away if you plug anything anything into the headphone jack on the right ear. Others also experienced the issue so it isn't just a lemon. Definitely do not buy.

These headphones have random, loud, and frequent bursts of static despite me fiddling with all the tuning settings and moving the dock to various different positions. Very annoying. For the price tag and brand name, I expected much higher quality. Do not recommend.

Purchased one of these to use with my turntable.  Upon connected from the preamp to the speakers there was an awful loud static sound. troubleshooting led me to believe the cable was defective. Touching rotating and moving the cable around i could get spurts of low static but never no static and usually obnoxiously loud static.  Requested a replacement which promptly came in 2 days.  Same exact issue. I started to think there was something else wrong but nothing else made sense.  Went to walmart and got a $7 cord and hooked it all up. Works perfect zero static.  After getting 2 of these that don't work correctly at all i am just sending them both back.  Awful product.

side note: I never put in a title for this review and it was auto generated somehow with "Works perfect no static" this is completely wrong and despicable that it would even attempt to add that title in on its own.

Major static was present even with the phone held right next to the headset. Often people who I called complained about the incredibly bad quality of my signal. Range was poor on Plantronics 650. I can no longer recommend this headset.

It had static.  It was not the line.  I had to buy a different phone

More static, worse sound quality than Yealink T21P handset. Returned for refund.

These are complete garbage. Soon as I took them out the pack and hooked them up to my phone there was a bunch of static. This was a complete waste of money.

Because is is a Sony product and a fairly expensive one I had very high expectations.  Unfortunately this product is terrible.  I have the base less than 10 feet from the headphones and there is an enormous amount of static.  I have tried everything but the static is always there.  I would not recommend this product to anyone

I am dissatisfied with this product. It creates an annoying static sound on the other end of the receiver and the person I am speaking to can barely hear me. I think it is something faulty with the plug into the phone. The plug snaps in fine, but if I move even slightly it creates static. I do not recommend this product and I regret not returning it in time to receive a refund.

I bought and returned this item and had them send me a replacement.  I returned the replacement too, both had the same issue.  the person being called heard static on the line.  I also didn't like the low volume.

When I plug it in it screeches so loud and has so much static on it, we can't hear. I tried to return it but I have missed the deadline for returning.
