does anyone know the gemini djx-05? http://www.amazon.de/Gemini-DJX-05-DJ-Kopfhörer-HiFi-Ohrhörer/dp/B000FVY18Q/ref=sr_1_70?s=ce-de&ie=UTF8&qid=1357921193&sr=1-70
I have some experience. Never owned, but my friend did for some time. The bass was a bit too heavy and muddy, and bled into the lower midrange pretty bad, but the upper mids and highs were actually pretty good. I found they went well with jazz and some rock. Didn't like them too much for classical. The construction wasn't anything to write home about, but it was ok for the price (around $40 at the time in the U.S.) and the clamping force was about the same as the Sony V700, so not too bad. All in all, my friend switched to the Shure 440, and never looked back, ended up selling the Gemini to someone for cheap. It's a decent headphone, but not wonderful or anything.
Just being honest here. Hope this helped! -BiggBenn
