I'm an audio engineer. I do FOH at a Casino in Michigan, have ran FOH and monitors at many venues/events over the years, worked as an engineer in recording studios for the past 10 years, and have also been a drummer, guitarist, and vocalist in dozens of bands. Back in February (5 months ago) I decided it was time that I get a set of IEMs. I ordered a set of G8's from Alien Ears. This is their 4 driver model. There weren't a ton of reviews out there so I figured I'd take a gamble and see what they were all about. They sent me an impression kit, which was very easy to use, and I shipped the impressions in. About 2 months later I got the G8's in the mail. The fit felt good, but they didn't sound very good. The left and right sounded very different, and there wasn't as much high end as I was expecting. For my needs they were unusable. I sent a couple emails in, called a few times, and after about a week of trying to get a hold of them someone finally called me back. I described the issues that I had and they said it sounded like a fit issue. I went to an audiologist to get new impressions done and shipped them in for a remold. I decided to upgrade to the G10 model (5 driver) because I was worried they G8 wouldn't have enough highs even after a remold. Another couple months go by, and I finally got the G10's in the mail. Immediately when I opened them up I noticed that the imprinted name on the right ear had worn off. These were brand new, I expected them to look brand new. The fit was good, but I noticed that the right side was quite a bit quieter than the left. When I gave them more volume I could hear a good amount of crackle in the right side. You can imagine my frustration after waiting 4 months to get my in ears which had been paid for back in February. I called immediately, with no answer. The next day I called and talked to Yolanda. I told her what had happened, and that I couldn't wait another 6-8 weeks for replacements. I requested a refund and she told me that they don't do refunds, period. I've bought a lot of stuff from a lot of different manufacturers, boutique, custom, you name it. I've never heard of a company that simply will not do refunds regardless of the situation. She told me that it's possible that a solder joint came loose during shipping, and that's why the right side is crackling. I told her that having them fixed wouldn't make me happy at this point, and she said my only option was to ship them back and have them look at them. So now I'll wait who knows how long for them to fix them. I will report back when I get them back, but so far, I'm not impressed. My warning to anyone considering Alien Ears: STAY AWAY!!!
