Ok, so I would like to add my two cents worth. I own only the A161p earphones and been listening to them almost exclusively (sometimes I listen to my V-moda Crossfades). I heard that Balanced Armature produced an accurate sound that to some may sound tinny. My Crossfades are pretty bass heavy I think, so I was expecting to have a lot of getting used to for the new earphones. What I got from the box was the richest, clearest, and most fun sound I have ever heard. They have a much warmer sound signature than I was expecting, and it was an incredibly pleasing. After about 7-8 months of hard use, the frail build quality had finally had enough, the casing on the earphones was coming off, and the left earphone finally shorted out. I sent them in last Monday for the warranty, worried that I may have voided it by duct taping all over it (the tape left sticky goo all over the earphones when I took it off). Never, never, never, ever putting duct tape on my earphones again. Now, within a week of me sending them off, I was informed that my new pair was on its way and should get here within a few days. So, bottom line, I am incredibly pleased with how MEElectronics has presented themselves and their products. Conclusion: Needs better build quality (for A161p, I dont know about the others), but EXCELLENT sound and customer service. I am very pleased with MEElectronics, and since there is a warranty for the A161p's then I would without a doubt recommend these to any budding audiophile that is on a budget.
