I'm afraid if that if I open them,it will break.But sides are not closed because he didnt drag the plastin onto the teeth. I really don't care as long as they work.No money for a new pair.
Gonna break mine out again...it's been too long since I heard them.
I gotta give props to whoever makes the drivers for these headphones.
Basically, I'm using the HD681Evo drivers for a project of mine, bought a pair of these just for the drivers, sort of threw the rest of it away, because I just need the drivers for a 3D printed headphone I'm currently making, and basically, this project involves super gluing a piece of plastic onto a magnet of the driver to hold it tightly in place and stiffen in to reduce vibration, just at this point, it's too messy to keep it like that forever. To make this story short, I didn't glue it properly, pulled on it to remove it, and the motha*****ing magnet popped out. It just fell out with a slightest tug, as if it was held inside the socket by another weak magnet. Great, there goes a driver I thought (btw, I ruined a Sony XB500 driver and a Sennheiser HD438 driver exactly the same way, apparently the glue used to keep the magnet in is very weak, so be careful around that area), but nope.
The driver was fine, the voice coil was untouched, so I decided to put the magnet back in, and then ran into problems, somehow, in some weird way, the plastic hole for the magnet shrunk, because the magnet didn't fit in anymore. I scraped all of the yellow rubbery glue out of that socket, sanded the magnet to make it clean and shiny, and then comes the reason why I give praise to these drivers (and my 3D printed baffle which is strong enough be ran over with a tank and survive, apparently, despite being light as a feather, woooo for my engineering skills). I managed to squeeze that magnet back into the hole with such force that I thought I'd break the floor underneath the driver, let alone the driver itself. Basically, think of a 90kg heavy guy using all of his strength, focusing the entire force through one thumb and shoving down on the magnet into the hole. It went in, and not a single piece of that assembly cracked. Amazing. Despite being held by just very thin plastics, that driver frame is strong as a rock. HD438 and Sony XB500 drivers snapped like toothpicks with 1/10th of the force. Just for a comparison...
So props to Superlux, their headphones might be cheaper than pretty much anything else on the market, but drivers are incredibly tough. Might I also add that it sounds exactly the same as before I broke it, it measures the same, etc. And it sounds wonderful, even at this early stage, my frankenstein headphones sound considerably better than a stock HD681Evo and are in 300+ dollar territory in terms of sound. These drivers have incredible potential but are ruined by the cheap design and build of the stock headphones.
Broke out my EVO's after months of storage...played some Liquid Tension Experiment and remembered why I bought these in the first place. Great bass that doesn't bleed all over the lower mids (foam mod) and still some detail there. Plenty comfy and easy to drive!
Gotta keep em'
I agree that using better leather pads could be good, other brand like ATH or AKG has more soft leather pads too
last night after rolling the pad to pleather I insert ring-cut cardboard to create space / distance (around 3mm) from driver to ear, and it raise the articulation, noticeably. more air moving maybe? But also create more clamping force. The mid bass no longer boomy and became cleaner, I finally disable EQ on my iPhone. On some track the sub bass rattle. I also notice many track resolve better - the classic "heard the sound I never heard before" Wow! I just want to test as many track as I want but my thumb hesitate to skip (lol and today I'm late to open my shop)
Now most track from The Back Horn suddenly doesn't sound so boring. instead of looking at watercolour painting now I'm looking at oil (lol thats what came into my head last night). I always thought that my J-Rock collection sound congested, flat, boring and polite, they must've tune their recording using super articulate headphone like Beyer / Senn?
But I had my doubt too. Maybe its the clamping that create it? I suspect that better pad can isolate better thus create more resolution?
I'm looking at AKG K550 pad. are they applied differently than Evo?
