I know the ER6s are ancient, but I'm wondering if anyone has any experience with replacement tips for these guys other than the Comply T200?  Would Shure black olives fit (without major surgery)?   Alternatively, are there any tips that are compatible with T200-sized tips that are well...

I've read a lot here about how the ER-6i work pretty well with the Shure black foams, but do the ER-6 fit? I couldn't find anything definitive on the search.

To sum it up, I love how they sound, but they make my jaws hurt. I've read in a older K701 comfort thread that some people experience jaw clamp. Has anyone made a breakthrough in K701 jaw comfort (perhaps positioning tips, etc.)? Would changing pads help? It seems the pads seem a little stiff...

Hi all: Is there a similar performing part that I can use instead of the SST502 on the PPAS? It's not stocked by Digikey and Newark has a minimum quantity of 1000.

I stuck the PIMETA-style LED indicator in with the PINT-style charger that's so popular: So the JFET current source should be at around 2mA (hopefully), and the LED should turn off at ~18V, and D2 prevents the battery from reverse biasing the LED when the 24V source is removed. My...

Looking at my enclosure choices, 2x9V doesn't seem particularly attractive now to power a portable PPAS. I've seen many people use a single 9V with it. I am planning to use the AD8610/AD8620/BUF634U combo. What do you guys feel about the SQ of 1x9V vs. 2x9V, on the PPAS in general, and in the...

So I've been looking at enclosures for the PPAS. I was considering the Hammond 1455C1202, but it seems a bit small and I didn't really want to do any surgery on it because I don't have access to shop tools. The J1202 just seems a bit bulky. Would a Serpac H65 be a comfortable fit for the PPAS?

I am using an AV-710 flashed to a Prodigy over optical. However, whenever I start playing any sound (including Windows noises), it would make a cracking sound. I remember seeing some sort of app that plays a background sound so all subsequent sounds would not have a cracking noise (or something...

Hi all: I'm thinking about getting a pair of im716s. However, I have a pair of Panasonic HJE50s, and I do not like their fit. If I found the HJE50s uncomfortable, would I suffer a similar fate for the im716s, or are IEMs significantly more comfortable?

I've laid out a CMOY PCB that's kind of MINT style -- to be mounted vertically in an Altoids tin. It's 20mm x 50 mm. Does anyone know if that's too tall to fit in the Altoids tin? I've printed it out and fiddled with it and it definitely seems tight. I would also appreciate any feedback on the...

Hi all: I have a few questions about various stuff about a cmoy project I'm doing: - Does anyone have the RK097 in a eagle Library? I did a search and went to Tangent's eagle library page, but didn't find anything. - For SMD resistors, are any particular models/brands recommended(like...

Hi all: Someone asked me to build one a meter that will check the capacity (current state of charge) of just about any AA/AAA battery simply by plugging it in. I have done some research, and I don't believe it is feasible. I know of the following ways to measure state of charge: - Open...

Well, AD1000s got here today. My first impression is that 3D Wing system is pretty cool and gives a comfortable fit. Unfortunately, I'm stuck with the onboard sound from my laptop, so I don't know what to say about the sound yet. Is anyone interested in nudies? If so I'll take some pics.

Hi all: I've been looking at this datasheet and it's been driving me nuts. I can't figure out how the output stage works... can anyone please take a look at it? http://www.rogerscorporation.com/dur...T-I9058A01.pdf The block diagram is on page 4.

This came up in the Headphones forum, and I just wanted to get a few more opinions on this. Does the 0404 have a recessed midrange?

Hi all: I've had the 580s for a while now, and I always think that (mainly male?) vocals sound a bit recessed with them. It's the only thing that bothers me about them (well, that and they don't fit perfectly with my glasses on, but that's not a huge deal). The bass and highs sound great. Am...

Hi all: I was looking at the schematic of a DAC (I think it was DaKiller's), and I was wondering what was the point of using isolators between the receiver and the DAC? Does the receiver output contain a lot of noise?

Hi all: Sorry for the off-topic post, since this isn't audio related. I'd appreciate any help from you guys though. I've built something like this: http://www.discovercircuits.com/PDF-...F/ONESHOTS.pdf on both a breadboard and a protoboard. However, only on the protoboard, there is a...

I am currently using a NPN transistor to drive a 555 in astable mode. A 4000 series OR gate is driving the base of the NPN transistor. However, when the base current is 0, the 555's output is high. The 555's VDD pin is connected to the supply, and the VSS pin is connected to the collector. The...

Hi all: Where would be a good (i.e., inexpensive) place to purchase and listen to either of these headphones? I know of hifi.com.tw, but I haven't visited their store yet. Are there any other good places for the 1000s and 900s

I was looking at some microcontrollers, and I came across these 3 packages. What are the differences between them? Would I be able to use a breadboard with them?

I am planning to get some teflon wire for braiding some interconnects/rewire my HD580s with the new plugs. Would it be a better option for me to buy some Belden 1585A or some silver plated copper teflon wire from eBay? Would a quad braid be ideal for these applications? How much cable...

Hi all: Today I noticed that my 580s seemed to be louder on one side than the other. The problem reversed itself when I put them on backwards. I thought it might've been the AV-710 control panel acting up again, so I adjusted the volume and I used a tone generator to test it. While using the...

Hi all: I was curious how the 8610 would sound in my PPA, so I took one from the ground channel of my PIMETA and stuck it in as the opamp for the right channel. I have the 637 on the left and the 627 on ground. However, there's no sound coming from the right channel. I am pretty sure the 8610...

I know this question has been asked before, but since it's been a few months, I thought I'd ask again to see if there are any updates. I contacted Long & Mcquade and Annex Pro (I live in Vancouver), but Long & Mcquade sells it for $135 CDN before taxes and Annex Pro do not have the cards. Annex...
