mod: Monoporice 8323 - Page 6

Nice! Painting is on my list of things to do to mine. What did you use to do it?

Rust-oleum Painters Touch Ultra Cover ("Also bonds to plastic!") Pink Gloss 

Thanks, No i didn't prep but after painting my first coat like an idiot (got newspaper stuck to it and other stuff) I had to sand it down using 150 Sand paper. This is the second-ish coat, i'll be sanding again lightly and applying another

 

Here it is after sanding after screwing up the first coat

Nice =)

I modded a pair as a gift - closed cell thin foam backing, upgraded cord and the v2.1 electrical mod - and hopefully the recipient doesn't read about it here. Interestingly they sound better than my older modded pair with all the same mods...highs are a bit better, clearer... Component variation shouldn't make that much of a difference, so maybe driver variation?

Anyway, I didn't go so far with my painting, instead only painting a metallic shiny blue mod logo.

Any update on this one?

Schematics and measurements are eagerly being anticipated!

I've done what most of the members in here mentioned with the acoustic foam, dynamat/fatmat, and cotton. I need to make some tweaks, but here are some pics of what I've done thus far:

 

 

 

 

 

They're done and she's ecstatic about them, very happy with the final results even though there were some blemishes 

For disassembly I only took off all the screws and ear pads/head cushion

I made some adjustments to my pair. Basically I added my silverstone foam to cover up as much of the inside of the cups as I could and added some more cotton. Tried messing with some stiff craft felt, but it killed the bass so I removed it in the end. I'm quite pleased with the end result. The bass has been reduced, but is still present to provide enough impact and extension. Overall the sound signature is now similar to my modded T50rp but with a little less treble. These don't really stack up head-to-head with my T50rp, but I didn't have any expectation that they would. I'm quite happy for the $25 I paid 

I've made two mods to my pair so far and I am pretty impressed with these.  They are great straight out of the box however could use some help in the treble area especially at the very upper end.

 

1. I cut the cloth material out of the cups so that there is nothing between the plastic grill and my ears.  This helped add a few db to the extreme upper end.

 

2. I replaced the stock cable with a silver cable from Ebay.  This added a bit to the overall clarity especially of the mids-highs.

 

The sound now sparkles like I want it to.  I may add some dampening to the cups as my next mod.

do u have a link to the ebay auction,,, im interested in getting new cable,,,  thnx

Alright, I haven't heard anything about anyone else trying this. Really wanted feedback first but don't want to keep waiting. I gave that pair posted above to my friend for Christmas but he is coming from some random Logitech headset...he says it sounds good but doesn't really have comparison. So I'll post this with the hope that others try it.

I don't have the time to do any measurements yet. I can't say yet how these will measure. I've modded 3 pairs so far and they sound great...I am regularly picking them up and putting them on, but sadly this mod doesn't do anything for comfort. =)

Here's my passive EQ mod for the 8323. It can be installed behind the driver or inline. The purpose is to attenuate bass and remove peaks in the 6-8k range to elevate the seriously lacking 3-5khz range, balance the sound, and reduce fatigue. The cans will be a little more forward and mid-oriented after the mod, but will still have solid (just not overdone) bass and should be less fatiguing. The can will work with far more types of music after the mod. Details in the upper mids and highs that were simply missing will be heard after the mod. It does change the sound signature so if you are a bass-head or like the 8323 sound, you may want to avoid (or use the less intense values, or buy two and mod one...).

This is what it looks like installed behind the driver:


Here's the schematic. There are also tables with different component values you can use to tune the circuit:


Here's the parts at Mouser. $10 shipped for one can, $15 for two. Also has spares in case you want to change some values.

If you do this mod with the parts from Mouser, it may look a little different from the photo as I substituted two inductors for cheaper ones with higher resistance. They do little to nothing to the mod but do make the mod smaller and cheaper.

I can post the inline (non-permanent, plug-in box) parts list if anyone wants to do it that way. I don't like box dongles hanging off of my headphone cords and the cans are cheap enough so I just bought multiples and modded a couple. =)

By the way, they're still on sale for $20 and change at Monoprice.

Anyone willing to try this out and give me feedback?

You don't need a fancy silver cable for these cheap cans. Just get one of the "Made for Mobile" cables on Monoprice, it's what I use for mine. Bonus is that they are cheap and if you are ordering a pair from Monoprice then it can be a part of that order.

Note: I don't work for Monoprice. I have and use about 12 of these cables. I've had one fail after a couple months (bad connection at connector) but Monoprice is shipping me another at no charge and I don't have to return the broken one. Effortless warranty service, I like it.
