As the title states, please help. I need to know if I should just plug in the thing or buy a step-down converter..

Which one for tracks such as this (listen in 1080p) :  

I want earphones which will never fall off your ears no matter whatever you do, but at the same time provide amazing sound quality and punchy bass trance/techno sound tracks. The Sony MDR-AS20J are the ones I currently use for workout and they will never fall off your ears. Even if you were...

My question is, would tracks such as the one I'm linking to sound amazing on the SR80i's (colorful,punchy,bassy as the track's impression was intended) ?   http://www.youtube.com/watch?v=NDD3b2Cbaw0   Listen in 720p = )   If you're lazy :p, I just want to know how good it represents...

Yesterday, they were fine. Today, my left channel had a VERRRRYYYYYYYY low volume, all of a sudden?!...I always keep it in pouch and take good care of it. What is up with that ?

The title pretty much describes what I want + Decent quality would be a plus. I work out really hard and sometimes my in ears start slipping because of my movement. My gym In-ears are the Sony NWZ-W252 (MP3 player and headphones in one). I want in-ears which will hold on to my ears like a baby...

So they are going for 65$. I'm a little shocked as that priced is relatively low considering the "legendary" status these headphones posses. Is amazon's listing trusted ? Why are they going for this cheap if they're that good?!...  ...

Please listen to this amazing, awesome track..   http://fieldsovgravity.com/2010/10/12/download-the-weekend-what-you-need/   At the beginning of the track, is it more bassy in the right phone and more vocal in the left ?... Please listen and comment. You will enjoy the song anyways...

Should I order it from amazon ??? (This is my only choice as I am an international buyer and amazon is the only place where they accept international plastic). :)     EDIT: What tips should I get along with my SM3 ?? (I listen to house musis, nujazz,acid jazz, and hiphop/rap)

So I was at the mall today and I saw an Ultimate Ears headphone and I was wondering which model it was...   1- The headphones themselves were kind of really huge with transparent replaceable cables. 2- It said SuperFi, but I couldn't catch which one 3- The box had a zebra pattern on it...

Hi, as my title mentions, I'm looking for IEMs that deliver incredible bass (really low), and yet deliver instrumentals and vocals clearly and without much effort. I really looked everywhere online and I keep hearing mixed opinions about a hundred pairs of IEMs which fit the profile. I'll be...

Hi,   This is my first post over here so hello to everyone!.   In the past few days, I've been researching on and on before arriving here and asking this question (title of the thread). I have read a lot of praise for both the M5 and the X5. I have been using a 5$ in-ear for about 6...
