Well before I moved last month, I broke the hinge on the AKG K167 Tiesto. The headphones were too new to get a replacement, so I decided to look for a donor body to harvest. After many hours of trying headphones on I decided on the Audio Technica SJ33 body.
The requirements I wanted were:
- 40mm driver
- somewhat tight headband for isolation
- compact design that doesn't have a large gap above the ears
- decent quality earpad material
- appear durable with thick plastic hinge *ahem*
- foldable in some form
- low price
Thankfully, I'm in Japan where Audio Technica is slightly cheaper because it is Japanese. The SJ33 was only $29.37 US. The earpads on these don't leak until around volume 40 on the Fiio E7, which is loud enough. They also isolate fairly well and I let a few friends try them already and they said it was "like being in your own world". They are on the ear compared to the K167, but I can deal with that since the material is not hard. The headband has no pads, but it doesn't hurt or anything. I will try and find a foam sticker or glue a piece of fabric under it.
Some pics of the process in order, although I didn't take a pic of every step. Stupid lens can't focus real close, so it's kinda blurry.
K167 on the left, SJ33 on the right.
The glue on the SJ33 was really gooey almost like rubber cement, so it was real easy to take apart with a blade. I simply cut around in a circle a few times and the driver eventually started to come upward everytime I pulled the blade out.
The K167 drivers however were very hard to take out. They used a stronger glue. I had to cut some of the frame in every corner to make the plastic flex so that I could pop out a corner just enough for me to pull it out.
Wires connected.
The K167 has a rubber damper or something, whatever it was, I just left it on.
I tested it out before I screwed it back together to see if it worked. Success. I didn't notice I accidently burnt a corner with the solding iron haha.
The soundstage has become more compact as expected because the SJ33 is a much smaller earcup. I might make a few holes on the SJ33 plastic panel inside to try and see if I can widen the soundstage just slightly. If not, just cover the holes with tape.
The next step is to replace the cable and jack. I'll have to look around to see if I can find a fairly cheap but decent quality cable. I will have a longer cable too.
The great thing about the new body is that it doesn't have the large silver rings which attracted too much attention. No one would even look twice at black on black headphones - that is until I put a nicer more durable cable on it, which I'm not sure if it will be black or not.
