Razer Kraken TE - left speaker has slightly more bass

After I finished to setup the headphone, drivers, and all of that stuff I did a sound test. I noticed the left speaker is a little more powerfull? The bass vibrations are more noticable to the left than on the right. At first I didn't care too much, the overall sound was good, but now I'm afraid that the speaker could be faulty. I don't want to use a faulty headset, considering the fact that It's new and I didn't use it for more than ~ a week. Ordered it from Amazon, if it helps. What could I do?
