Hello! About 13 years ago I purchased Etymotic Reserach ER-4P IEMs and then got Westone custom ear molds that the ER-4P plugged into. I've been using that setup ever since and have been very happy with it. Sadly, the right channel is now kinda sketchy and I'm pretty much positive it's the cable...

Hi there - I've had a pretty sad battle with headphones for the past, ohhh, 10 years. I just want portable, comfortable headphones that sound great. I travel a lot (think planes, trains, buses, etc.) - so my headphones see a lot of use. I want isolation both in the sense that I can't hear what's...

Howdy folks - I need to repair a headphone cable. I haven't cut it open yet - but I suspect it'll be the standard stranded enamel coated wire that is awful to work with. Couple questions: Is there a standard for what colors are what? Are there any good methods for removing the enamel...

Hi there - I need to put a new connector on some headphones. I'd like to put a good right angle 3.5mm plug on them. These Switchcraft parts look real nice. I found a couple fairly shady looking places that sell them, most seem to have large minimum orders or non functional websites. This site is...

I have Bose QC2 headphones. I know, I know - everybody hates them here. However, of all the high end headphones I've tried - they are by far the most comfortable. They don't have the sound quality of some of my other headphones, they aren't as portable, they use batteries, etc. - but boy do they...

Howdy - I work in a very noisy environment. Lots of loud lab sorts of noises, machinery noises, lots of people loudly playing music, people talking, etc. I would like to find a way to listen to music while at work. I currently have my Sony MDR-D66 eggos at work and my Bose QC2s at home (my...

Hi - A couple years back I built a couple of Guzzler's USB DACs. At the same time, I built a basic CMOY amp. Everything was powered off of the USB supply. Anyways - when I got it all put together - I discovered to my dismay one serious problem: it was very quiet, and very noisy. Wayyyyyyyy...

Hi - I am continuing my quest for the perfect portable headphones. My quest so far: Senn HD200: ok sound, huge, not very portable, no isolation whatsoever (what was I thinking?!) Etymotic Er-6: great sound, terribly uncomfortable, awesome isolation, very portable Sony D66 eggo: great sound...

Hi - I need a 5.1 analog channel sound card for my laptop - thus it needs to be USB or PCMCIA. I absolutely do not want a Creative Labs card. What's out there that is good? I remember hearing some mixed reviews of the M-audio sonica theatre (http://www.m-audio.com/products/en_u...ater-main.html)...

Hi - I want some headphones that will shield me from the outside world. I do alot of travelling (airplanes and buses) so I'm constantly dealing with noise. Right now I'm thinking I'll buy some Sony D66 eggos and some Bose QC2s. Why is this? I owned some eggos a couple years back and loved...

So - I'm just about done with this project... It's guzzler's USB DAC coupled with a CMOY. Now I just need to find a case for the bugger and I'm done. Here's it all in an Altoids tin: it's a bit of a tight fit - but it does fit, so I'm vaguely considering putting it all in one. But I'd...

So - I was wondering - I always see lots of talk about black gates, vishay dales, etc. when talking about good components for amps - but these are all through hole as far as I know. Are there any good series' of surface mount components, both resistors and capacitors, for audio amps? I've found...

Hi - I'm finally getting around to finishing the USB DAC that guzzler designed ages ago... I have a custom designed amp for it that will be arriving later this week. After building that - all I'll have to do is connect the dac to the amp, and then connect the amp to the headphone connector. This...

Hi - does anybody have any suggestions as to a good cheap place for PCBs in low quantities? I was just about to send an order to Sparkfun when I realized that they just recently DOUBLED their prices (now $5/in^2). a $20 order suddenly became a $40 order and I became a whole lot less interested...

Hi - Been trying to get this layout as good as possible - and this seems to be the best I can do. This CMOY is based 100% off of this design: http://headwize.com/ubb/showpage.php?fnum=3&tid=4508. The plan is to use the regulated +5V power supply coming from the USB DAC (Guzzler's design) that it...

Hi - I'd like to build a discrete op-amp - can anybody point me towards any good resources on the subject? I should mention that it isn't for audio - I need to amplify a 0-10V signal to 0-400V - and the only op-amps that I can find capable of this are made by Apex (http://www.apexmicrotech.com/)...

Hi - I just recently got an Audigy2 NX (the USB 2.0 Audigy). Anyways - sound skips occasionally with it. Well I dunno if you'd say skips, or stutters, or what. But you get the idea... I don't know what could be causing it though - it's connected to one of my laptop's two usb 2.0 ports. My...

Hi - can somebody tell me if the headbands are the same on the d-22 and d-66 eggos? Are they both essentially just a steel rod with a rubber casing around it? (that's what the d-66 eggos have) Thanks!

Hi - I'd like to get a sound card that can handle 5.1 analog channels for my laptop. My laptop has both USB 2.0 and PCMCIA. What cards would you all reccomend for this? Thanks!

Hi - I'm working on modifying an M-Audio Revolution 5.1. I've been using this thread: http://www5.head-fi.org/forums/showt...3&page=1&pp=20 as a reference - but I've come across a problem: The M-audio 5.1 board is quite different from the 7.1 board. I was expecting the same board with just two...

Hi - I really like everything to be board mount. Hell - I really like everything to be surface mount. But looking around at other people's work here, it seems pretty much everybody is just using panel mount headphone jacks. Are there not any good board mount jacks out there? Also, are there any...

Hi - I am going to be doing some modifications to an M-Audio Revolution 5.1 in a week or so, and I was hoping to get some before and after results of the modification. Is there any way to hook up another sound card to it and test it somehow? I have a Creative Labs Audigy I could attach to it...

Hi - what sources exist for good quality electrolytic capacitors in the USA? I know of Percy Audio and Handmade, but as far as I can see in their catalogs, neither stock Cerafines, and they both have limited selections of Blackgates. Are there other distributors out there? And is there really...

Hi - so I'd like to make a couple PCBs that I have drawn up in Eagle. I have access to a large number of CNC milling machines. I was told that they will mill out anything for me, as long as I can get them "g-code" for the board. Does anybody have any idea how to do this? I looked at the cam...

Hi - I need to buy a mini system for my brother this Christmas. All I need is for it to be small, have two speakers, have a CD player and AM/FM radio, cost somwhere between $150-300 (USD), and be available in the USA. Any suggestions? Thanks!
