Why wont the left headphone make as much sound as the right?

While they may be wireless, there is a cable that runs from one side to the controller on the other side. Check this cable to make sure there are no outward signs of damage.

Hi Terry,
if the headphones have removable cable, try another cable to check the cable connection to ensure it is ok, also check your headphones in another device to ensure it is not the device is causing the problem. also check your balance settings are central on stereo devices the balance can be set left and right. if the cable is fixed try moving the cable over the whole length with music playing to see if the speaker makes any noise at all this indicates the cable is broken, as your headphones are only 1 month old you have full garantee from the maker, as long as you can show they have not been damaged through rough handling or overloading with too loud sound. it can happen that new headphones fail shortly after purchase due to component failure or weak connections.

I hope this was useful.

This worked for me! Just reset headphones as in video.

bad signals

I have this issue as well, you need to (depending on what software you use) duplicate the track and set one input to US-144MKII Left and the other to US-144MKII Right. As far as I'm aware, this is the only way to get an even sound..

most likely cable is very loosely contacting the jack or earpad. Will need to be taken apart and soldered.

Have same problem. Play with the plug in the socket. I'll bet it you can occasionally get both working. Not a solution since it probably won't stay working. I have an old plug and it fails too. I'm afraid they did't make their plugs to the right tolerances. Used to work once. Annoying for this expensive a headphone.

It sounds like you actually have 2 wires closely wrapped together. They are very fine and you have to make sure that you have separated all of the wires from each other. Generally you will have a red wire and a copper colored wire for the right side and blue (or green) and copper colored for the left side. you need to make sure that none of these little wires are still mixed with each other, otherwise you have a dead short and the speaker will not work. The insulation is very thin so there is no need to strip it, the insulation will burn off when the solder is applied

check the adjustments in your mbox is there is any option to move the noise left and right if there is one so put it into centre

your headphones are bad sounds like cheak out the new seinhezer hd280 pros ok 99 bucks best they make
