Does the grado SR80 need a amp ?

I have got the ER4S + Xin supermicro amp, its a excellent IEM

Thanks for this info. iPhone uses Wolfson WM8758 audio codec chip, same as the one used in iPod video. So the sound quality should be similar.

Has anyone used a iPhone with portable amp and a Ety-4s ? I have a 3G ipod with this setup. Does a iphone have similar sound quality ?

I had a similar problem with my ETY-4p, the left earpiece stopped working, and my 2 warranty period had expired. I send the unit to Etymotic and they send me a new one for $50 (+$6 shipping). In my case the transducer was bad on left ear piece, and the wires were worn out.

I prefer Ety-4s as compared to shure, Ety is more comfortable to wear and excellent detail, and the quality of phone is better than shure.

I own a E2c and a ety-4s [ with the converter cable], I feel that there is a huge difference in sound quality between both these headphones. Ety-4s is a much better the Shure E2c.

I have a Ety4-p/s and a Shure E3c, I would say go for a Ety4 if you have a external amp. You might not need a amp for a ety4p with iPod. Ety4s sounds a lot better than Shure E3c . I don't have a E4c so I can't compare them.

It took about 5 days to get it..

I received my supermicro last week from Xin.

Illiad, There is lot of difference in sound quality with the supermicro amp, this amp has 50 ohm resistor in it [ acording to Xin ], so ety-4p is almost equal to the sound quality of ety-4s.

Here is a picture of my portable setup

Here is my portable setup .. iPod -- > JMT mini-mini cable --> supermicro --> ETY-4P

Dr.Xin says supermono should be available next month. Dr.Xin is still working on the look, sound and features.

When is this supermono going to be available ? http://www.fixup.net/talk/topic.asp?...erms=supermono

I use Ety 4p with the foam tips on airlines, i find the foam tips better than 3-flange eartips for isolation.

Shure E2 are great for workout/gym, but I prefer Ety-4p for the clarity. Ety-4p is not bad for jogging if they are worn properly. The foam on the Ety's are a lot better than Shure E2's.

I have few questions regarding A900... Does the A900 need an amp with the iPod ? Will it improve a lot of sound quality with a portable amp like Xin mini ?

I have used shure E2 and they are comfortable during sleep.

Is A900 unamped, better than ER 4 S unamped ? How does the A900 compare to Shure E2 ? I have a shure E2, and I would like to buy a headphone without amp. I would like to get same sound quality as the shure E2s.

Music direct rep said, they would ship Shure E3C within a week.
