I currently have a pair of Etymotic HF-5, and I use the gray triple-flange ear-tips. I love the sound of them, but my ear canals are getting sore, after a few hours of use every work day for two years. So, I'm looking for an over-the-ear headphone I can listen to at work until my ears heal...

For a while, I've been listening to my headphones (Ety HF-5) driven by my TDA2030A-based desktop speaker amplifier. I finally build a CMOY-type amplifier with an LM6172 and it seems to have more impactful bass than the TDA2030As did. TDA2030s are driven straight off a voltage-doubler from a...

Ok, I guess I'll build a 6V or so boost converter and build the amp with an 8397 and see how it goes.

So, I built a headphone amp using a TDA1517P that I rescued from a pair of cheap desktop speakers. Has lots of hiss, but adds so much impact and clarity to other sounds, that I figured I'd better keep using an amp. Anyway, I built it on a radioshack generic PCB, and it's been bare, on my desk...
