Simple keep the receipt.

Good on you man.   Shure iem generally very durable. Now don't worry about price just enjoy music.  

  Erm who told you that? Impacted ear wax is a sign that you did need maintenance.   You still need to keep your ears clean and healthy like every other part of your body. If you're a swimmer or spend time in the water you regularly use drops to keep them dry and free from infection. If...

T10i is not worth it.   You have to decide what is worth it to you. We are not in your position and can't tell you what to do. Good luck.

Overall I think the QC25 is better for travelling. The sound differences you guys have stated is true though. I'm just happy for the peace and quiet. 

Depending what you buy there may be an included case. That's what I use.

I'm really missing my Blox while they are off in Thailand being repaired.    I went from 2 Blox, 2 Yuin, 1 Apple buds to nothing. Now my ears are hurting from wearing headphones and my ear canals are rebelling against my iems. I might just buy a cheap pair of Sony or Panasonic instore to tide...

Where are Astell & Kern from? I see their website is in English or Korean.   edit. I just found out they used to be iRiver.

I was just typing the same thing.    I have the 425s as well and they have a particular sound to them. You need to demo them first.

Get the iems first, listen to them and then worry about the cables.   I use my 425s with comply Ps or Westone foams. Coupled with hardware bass boost when needed it's enough for me. Not as bass heavy as 215s but bass quality is much higher. Still it won't be enough for you.   Look at the...

  That looks great man.

  Aye but as mentioned it can be preferred sound sig. I have the 425 and the Classic 5.5 and I like the pairing. It's not bright to me as there's a well documented roll off and the wolfson in the 5.5 smooths things, at least to my ears. I can compare the 425 to darker, bassier iems costing...

I've used different types of Comply tips on various iems. I also have the Shures and Westone combo packs. In general the Complys don't last as long. I use the P series and they are really soft once they warm up with your body temp. I think they are more porous than the others which helps with...
