Twist the entire bezel on both the front and rear of the cups. Do not unscrew the yoke screws.

I disassembled my Openheart OH2000 headphones. It is a 50mm driver. They disassemble easily. Unscrew both the front and back pieces from the cup, apply uniform heat across the entire cup (use heat gun and rotate cup back and forth), then the driver should push out easily. Attached are photos...

Driver size was not an option, just headband color.

The OH2000 has a headband color choice. I picked black as I figured the red stitching coordinates a little better overall. Mine are supposed to arrive tomorrow. I'm expecting to replace the drivers but need to hear for myself first.

My order still has a day and change for them to acknowledge. I guess I won't expect it shipping for some time...if ever. Was looking forward to trying a driver swap.

Cool! Are those drivers available to purchase anywhere?

Which drivers do you plan to install? I just ordered the openhearts and am curious about modding. Will you stick with chinese drivers or do something like the Nhoord ones?

Bummer. I ended up with two bad buds out of four. QC does not appear to be an ISN strong point. Penon sent me a replacement pair (where I got the other bad bud). I bought directly from Penon, but I suspect they will work with you without going through ali...unless you want to leverage any...

I got my balanced cable to work with the functional D02 combo. So between two sets...two bad buds. Thankfully, one L/R pair is working amongst them. The other pair is complete dead. Fit has been a challenge with these. I gave up on the spiral dots as the right would slip repeatedly over a...

I got my replacement D02. They just sent buds, not a new pack. Tried them with original cable and no good. Same issue, one bud won't work. So its the cable right? Umm no. The replacement pair also wouldn't work on an extra cheapy SE cable that originally shipped. I finally got a pair of...

I've been fooling around with my defective D02 buds and found something interesting. Neither will function on a balanced cable. Both actually will play on an imbalanced cable, but only individually....one always has no sound Three different unbalanced cable, always the same. I presume one...

Consistent right side driver flex. Not good, but maybe a sliver lining is that they should be able to figure our what they are doing wrong in production to cause it. My Left was fully dead so I had the opposite 'imbalance' :stuck_out_tongue:. If it had functioned, I wonder if I would have seen...

If you like woodgrain and don't mind paying $60-$70US, try out the Guideray GR-T20. Everything about them has been real nice for me.

Penon has shipped me a replacement D02 set for my initial bad pair. I think its coming slow boat, but on a good note they don't want the defective pair back which alleviates me of the physical return hassle and gifts me an extra mmcx cable and some tips. Kudos on Penon. Now to see if ISN can...

Although this is not the appropriate thread, can anyone direct me to a good tutorial on MSEB? I'm playing with it on an R3 Pro with my guideray T20. MSEB seems crazy powerful. I can indeed make my IEMs sound like just about anything...good and bad. Honestly, its a touch overwhelming...not...
