Yes, that is what I am thinking. I remember reading a post here a few months ago where the poster was commenting on the difference in signature between two "old" NICEHCK graphenes bought a few months apart. As I remember it, he described the difference as more subtle than what I am hearing...

Could it be that there are different versions of the "old" Graphene out there? A few months ago I bought a graphene MX760-shelled earbud with similar specifications (resistance, sensitivity, response range) to the NICEHCK "old" graphene. However, it doesn't sound anything like the NICEHCK DIY...

Thanks! I will be ordering one myself - too cheap to pass up.

May I ask where you found it for $25?

There are still a couple of the RunAbout Plus + Zen Lite bundles left, both on VE's homepage and on Aliexpress. The standard edition for $98 is sold out, so you have to choose either the one with charger and batteries or the one with power bank. The current batch of package deals was made...

I've only got into earbuds last summer. Been following this thread since then, though haven't posted much so far. List of current earbuds: AUGLAMOUR RX-1 FAAEAL 64ohm FENGRU DIY EMX500 JOYROOM JR-EL117 K's K300 Samsara K's K600 Moondrop VX Pro Mrice Baldoor E100 NICEHCK DIY Graphene NICEHCK...

I have experienced electric shock when using the AuGlamour RX-1 with the Zishan Z1 as a DAC/AMP from the PC at work. I now only use plastic-shelled earbuds with the USB-powered Zishan Z1.

It was sealed, but it looked like it had been done by a cheap home sealing device (heat marks and sharp corners). There are signs of wear on the cardboard box so it appears to have been re-sealed. In addition to the scratches on the screen there are friction marks on the backside; there was...

I am disappointed that I received a used unit (it is not just the screen) when I thought I was getting a new player and most people seem to have received a new one. It might still be good value but I cannot help being disappointed nevertheless.

Thanks. I have been speculating about this since I noticed a pattern in in the scree surface when looking carefully. I also read about someone with a similar issue with the C4. I haven't yet made an effort to see if it is removable as I was hoping to return the player (thought this seems...

This is how my player looked like straight out of the box: screen covered in scratches + several other signs of wear. Joybuy's customer "support" has been a joke. [/IMG]

Thanks for the explanation!

I'll post some photos to avoid any missunderstandings. I'm a newbie at this so my use of the terminology is probably a bit confused. When I measure sleeve against tip/ring the display shows the letters OL (Open Loop), the same as when the probes are not touching anything. Once or twice I got a...

Ok, so I got me a multimeter today and I've already made a few measurements on the Yinman 150. The multimeter registers no (or close to none) resistance either between tip and sleeve or between ring and sleeve. Between tip and ring I get a stable result around 310 Ω. After bending the cable...

Thanks for the replies so far! Unfortunately, I do not have access to a multimeter. I've been thinking about getting one for a while, so I might stop by the local hardware store on my way home from work tomorrow. I did shoot a short video sequence yesterday that I'm going to send to the seller...

I just received a defect Yinman 150 earbud from a seller on Aliexpress and I'm currently trying to figure out the source of the issue. The seller has asked me to provide a video documentation of the problem. However, it is not the kind of problem that is easily documented in a video, especially...
