Here is my latest little project :D
These Headphones started life as a birthday present that I gave to my younger brother years ago. He has really enjoyed them but has given them a hard life with me having to replace the jack multiple times.
I finally decided that the cable had become too short and too flimsy and was due for replacement. I replaced the cable with something a little more substantial and a proper 6mm jack. Unfortunately during testing we managed to turn the gain on one of my headphone amps a little high and blew the element.
I sorted him out with a new pair of 419's for his next birthday, since then the 418s have been sitting in my garage for a few months gathering dust while I have been working on other projects (hybrid valve guitar amp/JLH class A/wide baffle speakers).
I stumbled across the parts express headphone elements after picking up some replacement car speakers. I put an order through with the elements, a bunch of tweeters and some ferro-fluid on Thursday.
When I arrived home from work today a box of goodies had arrived at my door :D
I had pulled the 418's apart when the element blew and had not bothered to put them back together. Today I removed the sealed surround using a razor blade and pried the old elements out with a small flat headed screw driver.
There was not quite enough space for the new elements because they are a little wider than the stock ones. I balanced them on top of the original mounting and tacked them in place with a couple of drops from a hot melt glue gun. I then sealed right round the edge of the element with hot glue.
I used a little modelling clay and polyester fill to deaden the cups and added an extra N45 6x6mm neo magnet to each of the drivers for that little something extra :)
First impressions, these play deep!! Awesome bass - deep but clear. I have not made my mind up on the mids yet but treble seems decent with these.
Further listening impressions to follow....
