I'm not happy with these headphones.I can't get them to fit confortabley in my ear.I have tried to adjust the piece that goes aruond the ear but they feel like they are falling off.If you bend over they fall out.I stopped using them.

When I lost an earbud and asked if ADV offers replacements, they said no but gave me 20% off + free shipping on my next purchase! I bought another pair because they're so perfect. Clear, responsive and the case is nice. Thank you for being awesome :)

ADV customer service was responsive and delivered within their estimated time frame. ADV also did a great job at designing my full shells for my universal fit in ear monitors. The custom fit of the ‘Eartune Fidelity' enhances the fidelity of the monitors and also improved the noise isolation.

I am beyond happy with how these fit and sound. The audio quality is noticeably better than the stock tips, and these custom inserts finally allow the Beyerdynamic DT 70 IE to perform exactly as designed. The acoustic seal gives me the isolation and flat, accurate reference sound I need for music production to properly dial in my highs, mids, and lows. Since the DT 70 IE wasn't listed on their site, I reached out to customer service, and they were incredibly helpful. I got my molds done at a local audiologist, shipped them along with my IEMs, and received the completed tips about 6 weeks later. They are so easy to insert, and I’ve worn them for hours with zero discomfort—even with glasses on. I highly recommend ADV!

Amazing! Customer service dealt with my need to get a new product fitted for custom molding all while I was on/off tour. Weeks and weeks of email threads and nobody skipped a beat. I was well taken care of by the team. Couldn’t be happier!

Quick delivery of the case and it seems well made/durable. I didn't realize how big the case was, but that's on me. It can fit multiple IEM cables.

I placed my order and I had the product Within 3 days I was pretty happy I needed it by the weekend. The wireless in-ear monitor transmitter receiver works great it's very small two other people in the band that I mix for have them.
