Sony MH1/MH1c Vent Mods: Reduces bass quantity; tighter/punchier bass kicks; reduces veiling in the lower mids resulting to more detail.
I'd like to share the vent mod that I've done based on the modifications suggested by head-fier mods and also RinChoi's Blog.
So special thanks to everyone responsible for the various modifications for the MH1/c.
- Band-Aid Clear (Plastic)
- Earbud Foam Cover
Cut a piece of plastic band-aid; enough size to securely cover and stick on top of the top vent. My reason for using Band-Aid is because of the small holes on them which will serve as your pin-hole vent. Notice in the photo below, the hole is aligned on top of the top vent. This is important because sealing the vent completely IMO eliminates reverb thus, making the bass kicks sound unnatural and plasticky.
STRAIN RELIEF OPENING
Cut 4 pieces of foam from earbud foam covers to serve as dampers on the strain relief openings. Feel free to choose other foam materials that you see fit for your mod. The size of the cut pieces is 4mm W x 5mm L. You can increase the length if you want more dampening.
Now insert the foam pieces in the strain reliefs. You'll need two on each side (front and back sides of the strain reliefs).
Here's a photo of the strain relief with dampening:
I highly recommend this mod to those who want something reversible and easy to do.
Happy listening to your MH1/c with vent mods!
