A couple of months ago I reviewed the Sennheiser X320 Xbox Headset and came away very pleased with them, once thing I loved about these was that it didn't need batteries to operate as it got power from the XBOX 360 console itself. I had the opportunity to get these Turtle Beaches with similar features, but unlike the Sennheiser these are wireless. Even though they are wireless they still do not require batteries because the wireless transmitter itself connects to your console to get power.The first things that drew me to this headphones was the fact that these are fully compatible with both my XBOX 360 and PS3 console. With it being PS3 compatible that means it uses Bluetooth as well and Turtle beach took advantage of this Bluetooth feature to make it compatible with your Bluetooth phone, meaning that you can receive and answer calls while you are playing the game. When you receive a call, the headsets automatically mute your in game chat and allow you to answer and talk to the person on the other in through your headphones while still playing the game. This is a very cool feature because it's very frustrating being in the middle of an intense game having to stop to answer a call.Another cool feature of these is that there is an AUX in jack on the wireless transmitter that allows you to connect your IPOD, phone, or other music device and pipe music into your headphones while you play.Sound quality may be slightly better than the Sennheiser's but I noticed in NBA 2K12, that the announcer volume was quite muffled and drowned out by the crowd noise. No problem, I just pressed the sound field button and it switched to a different sound mode, and then I could hear the announcers clearly. This is a great feature because some games seemed to be mixed differently than others and the sound field button helps you get the best sound available for the game you are playing. There is also an Tone button as well that allows you to switch between different combinations of treble and bass. It should be noted that I didn't have the same sound issue with the Sennheiser so I am not sure why I did with the Turtle beaches before changing the sound field. I think the basic sound produced by these headphones is good especially, but if you want true surround sound, then you have to shell out another 70 or 80 bucks to purchase an adapter. To me, it's not that serious and I only use these headphones late at night when everyone is trying to sleep or when I don't want to be distracted by outside noises.In game chat works well with both the PS3 and XBOX 360 and the fact that the PS3 uses Bluetooth and the XBOX 360 does not is not a problem, instead of creating a brand new interface to work with the XBOX 360, Turtle beach just made the Bluetooth compatible with the XBOX 360 by using an included wireless chat adapter that plugs into the bottom of the XBOX 360 controller and connects via Bluetooth to the head phones themselves. Pairing was a bit of a pain because sometimes it doesn't always work, but when it does it sounds great. If you don't want to use the wireless connector, then you can use a wired adapter instead. (sold separately, of course)When fully charged, your headset provides up to 15 hours of gameplay before needing a recharge, but if you run out of a charge, not to worry, you can connect the included extra-long USB cable to the headphones and then to your console or any other USB enabled device and play while you charge. Keep in mind you don't have to have the headphones connected to your console while charging, in fact I was using these headphones on my XBOX 360 while charging them via the PS3.These headsets are quite comfortable much like the Sennheiser's are, and considering how much time a person will spend wearing them during marathon gaming sessions they SHOULD be comfortable, and where the Sennheiser's succeed, so do the turtle beaches. The button placement and volume controls on the headphones do however take a lot to get used to, there are two volume controls for the game sound and in game chat, but there are also other buttons for Bluetooth pairing, power button, chat level, mute button and a couple of others, until you get used to the button placement you will more than likely finding yourself taking off the headphones because you can't remember where everything is. One area in which I prefer the Sennheiser over these is that to mute your all you have to do is rotate the microphone up over your head; with these you have to physically press the mute button. However the mic arm itself on the Turtle Beaches is flexible and can be moved around in virtually any position you want, with the Sennheiser, the mic arm is rigid, and may be prone to breakage if you are not careful.While I am impressed overall with the sound quality and extra features there are a few complaints I have that prevent me from giving these headphones a perfect score.First, while I had no issues when playing the PS3, I would notice that the XBOX 360 controller would sometimes randomly disconnect from the XBOX console itself causing the "Please reconnect controller" message to appear on the screen. Every time this happened I seemed to remember the controller reconnecting itself automatically, but even still, if you are playing a game that requires split second thinking, then these random disconnects will almost certainly mess you up. I am guessing this may have something to do with the controller trying to work with the Bluetooth transmitter, but I am not 100% sure. It's only happened a couple of times, and hasn't happened since. (crossing fingers)Secondly, on both the XBOX360 and PS3 the game sound occasionally gets lagged and garbled and sounds absolutely terrible. This more than likely could be caused by interference with my other wireless devices in my home. Which is another reason why I prefer wired whenever feasible.Finally, when using the in game chat, you can slightly hear your own voice echo while talking to others, the Sennheiser didn't do this, and neither did the standard XBOX 360 mic or PS3 Bluetooth microphones. It gets rather annoying, and I haven't figured out any way how to turn that "feature" off. To add to this, even with Mute on, I can still hear outside sounds coming through the mic even though people in the game cannot.Speaking of Mute, Turtle Beach decided it would be a good idea to "notify" you with an ear piercing beep every few minutes or so, when you have Mute turned on. This is a good example of them trying to do too much. I KNOW Mute is on, I don't need to be notified with this constant beep. I hate my answering machine for the same reason, the constant beeps are extremely irritating and to me are almost akin to the sound of someone clipping their nails.I also need to mention that in addition to the mute notification, I have also noticed other occasional out of the blue annoying beeps and tones that sound even when I have everything hooked up correctly and my battery is sufficiently charged and I haven't figured out what was causing these sounds. On quite a few occasions, there also seems to be a persistent buzzing sound that is audible especially when the game volume is down and I have yet to figure out what causes it and and it comes and goes. Recently it became real loud; even noticeable during game play, and I finally went to the transmitter, unplugged the line jack and reattached it. I also moved the transmitter away from my consoles and that seemed to resolve the issue. In any case, with my Sennheiser's, the only sounds that come from them are from the game itself and other players and that is the way I prefer; just do what you are designed to do and do it well.All in all a great set of headphones that work well and produce great sound on both the XBOX360 and PS3, but expected issues with wireless rear their ugly head possibly during the most crucial times of your games. The voice echo and the occasional buzzing that comes from the headphones can get very annoying. The button layout on the headphones themselves will not be very user friendly when you first use them. Finally, the random R2D2 beeps can also get irritating if you are super sensitive to certain sounds like I am.While I like these, they are definitely not a 5 star product in my opinion. They do produce great quality sound and when they are not buzzing constantly, I am quite pleased with them despite the other flaws. I went back and forth between three and four stars for this product but decided to bump it up to a four because perhaps I figured out how to resolve the buzzing issue. Even still, I haven't used my Sennheiser's since I got these, but may switch back to them from time to time when the beeping, echoes and especially the buzzing become unbearable for me and I need a break.UPDATE 01/09/2013Over the past month or so, I noticed an annoying buzzing coming from the right headphone. At first I thought it was due to interference of some sort or a result of the 3.5 mm stereo cable having a short in it, but I replaced that cable, and I still experienced the buzzing. I later discovered it wasn't electrical, but a mechanical problem from within the headphone as if something has came loose and is vibrating. I discovered if I squeeze the right ear piece while the music is playing the buzzing stops. So in order to make this permanent, I just folded up some electrical tape and put it between the ear piece and the bracket that holds it. (see picture for what I am talking about).UPDATE #2 11/04/2013The buzzing issue has become unbearable, even with the tape fix I described earlier this year, it still occurs. As a result, I no longer use these headphones and have gone back to using my Sennheisers's exclusively. These headphones lasted for a little over a year, and of course right after the warranty expired. Dealing with products that only last for the warranty period is frustrating and as a result I am forced to bump my rating down to 3 stars instead of four.
