I've been in contact with Etymotic, trying to figure out what to do. They have replied: "I can't guarantee this will never happen again but it is not a known issue. We now have a new design. The change in design is that the plug is now angled." They offered me to return them for an exchange. I...

I have now had a chance to try the Total BitHead with Sennheiser HD595 but I am still deciding which amp will better complement these cans. As I can't compare them, is anybody using the iBasso D2+Boa with the HD595?

I am looking to get the iBasso D2 to use with my HD595's and was wondering if this is a good combination. I will be using this set up with a iPod nano and with a computer (using the iBasso as a DAC). I already have a good LOD and I want to know if this amp will improve the performance of the...

I have a very strange problem using my Etymotic Research Hf2's and iPhone. I recently returned my original pair to Etymotic for repair (no sound on left side) and got back a replacement. This replacement produces sound from both earbuds but the microphone and the button on the microphone do not...

I have a Total BitHead amp that I use with my new HD-595's with high quality AAC files from an iPod nano as source. I was wondering if HeadRoom's SendStation iPod Pocket Dock Line-Out Mini-USB would improve the quality of the iPod output enough to warrant the investment. Has anybody tried this...

I've been looking online for the 50Ω version of the HD595 and have not been able to find them at comparable price to the 120Ω version. I'm assuming that the 50Ω version is newer?? I will be using a Headroom Bithead amp to drive these, is this amp adequate to drive the higher impedance 120Ω HD595?
