NEW PRE-ORDER More coming in 4 weeks
Version 8 is the latest lightest weight version with the tightest bass and wider image while still eliminating any sibilants - this latest version rataining pin point imaging… our best lightest mod yet! now with standard headband, HIFIMAN ARYA Headband.
Utilizing Patent pending multilayer JM Audio Proprietary Fractal Mesh Technology™ and Fractal Fiberglass Porous Carbon™. I only make one a day - I take orders first. I literally match the driver discs for each pair (from hifiman) the discs all ring differently - I spend time to match em BEFORE the mod with high temp elastic rubber so they are non resonating at higher frequencies and they resonate deeper so they give a better matched experience. This is the first thing I do - it makes a huge difference instead of just throwing uneven amounts of glue on the disc where the driver sits like they do at the factories and hope they (L+R) sound similar- I test and mod match the resonate ring - that first then I get into the actual mod. It takes me 3 hours to make each one and a lot of raw materials to hand cut and place and test the R9 JM Edition headphone- JM OCD Extreme Stealth (SE) mod which is EXTREME in every way. I re-wire the R9 and R10 so they are compatible with most owners regular/typical left and right 3.5mm wire which connect from the ear cups and are compatible with most XLR, TRS 3.5, TRS 6.3 or similar wires on the ends. The connection is more universal and direct to each ear speaker - unlike the shared wire which loops through the headband in the stock version and degrades sound. This allows much higher fidelity for purists since the wiring allows direct left right connections from a users amplifier. The compromised "blue tooth module" will not work after I mod the R9 or R10.
Version 8 lighter and best sounding version. With more controlled bass and wider stage - detailed and non sibilant the best version to date.
The cups are re-enforced and made as inert and as solid as I could make them- treated on inside with heavy heat resistant heavy duty sound liner while using a stealthy technology of hand cut custom fiberglass mesh and porous carbon in dual multiple fractional layers. Each box is hand numbered and signed After the 3 hour mod - I listen to the headphones for 10 songs - all songs selected for different reasons to ensure they sound like my reference Stealth mod and measure the same- if they meet all requirements- I sign and pack.
