Question: What is the power source for the chair, and I use HDMI so would I still be able to get sound to the chair
Document: Hahahahaha All in all, I would definitely recommend this chair. It's nice and big so I can sit on it cross legged if I wanted, the sound is really awesome, it's insanely easy to put together and super easy to move around. The cord to hook it up to a power source COULD be longer, but it's great otherwise. There is no spot for a USB cable, I was asked that and can't find who did ATM.
Chair rocks, a little padded pillow for my rear end and is very comfy. Sound is really great go easy on the bass or you will get a back massage. I use the wireless so do not forget to buy a speaker jack (3.5mm) to USB cable, works better that way. You can buy a power adapter for the wireless unit online for it just make sure you follow the specs of the wireless unit voltage and amps or it will not work you will get a lot of noise.
Nice feature to prolong battery life, but would still like a DC converter for the transmitter. Should be able to pick one up without too much $$$.
This chair looks nice and the speakers have good power and clarity.I just wish it was up to date with modern technology of HDMI and bluetooth.
After a month of use the chair is leaning to one side due to a flaw in either the design or a faulty part. I am still trying to get a replacement through Xrocker. I emailed them and gave them all of the information requested but after 12 additional follow up emails they still have not gotten back with me after that point. I will never purchase something from this company at this point. They won't even fulfill their warranty.
lets get to why its is a major waste of your cash, the speaker system's jacks are so poorly designed both of which in both chairs i bought, yes i bought two of them, were no longer of any use within a week. the jacks had ripped themselves out of their holster and pieces of electronics with them. One chair happily ate its own power cable! wrapped around the pole and it was no more. It also left black crud that i cant get up on my carpet.
My first impression was positive since I really liked the look. I did not find the chairs as comfortable as I would like and have to admit there is a bar that goes across under your legs that can be felt through the cushion. This made the viewing experience a bit annoying and I was tempted to return the chairs. However, I just got the adapter and was able to use the chairs with the speakers and was pleasantly surprised by the experience.
My wife and I ordered 2 of these as a wedding gift so we could play Xbox together. One of the power supplies was bad, but I contacted the manufacturer and they shipped out a new one immediately. Sounds quality is good, and chairs are comfortable for gaming as they keep you upright (would not want to use for relaxing and watching a movie).
Chair is comfortable to sit in and was very easy to put together. The power cord still has to cross the floor so it's not completely wireless, but it's definitely one of the nicer game chairs I've seen and the sound is great!
this chair is beautiful and amazing. i am a true audiophile so i am picky with my sound equipment but this chair surpassed my expectations. the speakers can get very loud, the bass from the subwoofer is very powerful but not over-consuming. people say that you need to turn up the volume to the max to feel the vibration which is FALSE. Along with a volume dial there are two separate dials next to the power button.
Answer: The power source is an A/C plug into the wall.  Then there is a small device that plugs into the audio output of your t.v. and transmits wirelessly.
