why not you get 2-3 different headphones since your music taste encompasses a wide range.

If you're serious about your music then sure, I don't see why not. But I'd test out multiple headphones/IEMs before coming to a conclusion on what is truly your own taste.

I used to think I like neutral sounding phones, but as it turns out, I tend lean towards treble and slight colour. Also, knowing what parts of a pair of headphones music signature you prefer will make narrowing down your choices much easier for future purchases.

It's something like White/Pink noise, just a track which you put on loop when you're burning in your headphones. As for the way your friend is doing it, it's not really recommended. It's best if you let your headphones rest after 3-4 hours of burn-in, as not to wear them out too soon due to continuous use. Also, volume should be about 5-10% higher than your usual listening volume, NOT at full blast.

Tracks used for solely burn-in purposes usually encompass the entire sound spectrum(?) from the highs to the lows, allowing for a complete burn-in. I've seen people use just songs for burn-in, but using a specific genre... I'm not too sure about that. If your friend used metal music for burn-in then his headphones might not have a full burn in due to the nature and sound sig of the music genre, bass would still be not fully burnt in, for example.

There is no right or wrong music/songs to use when burning. Just use whatever you want. The main purpose of burn-in is to pump as much music into the drivers so it will loosen up over time, and when it does, it has more space and area to move in between the diaphragm so they can push more air out, resulting in a more dynamic sound and better bass response across all frequencies. It's similar to wearing new shoes, you might get blisters or sore feet in the beginning, but it'll eventually break-in and settle with your feet size.

RRP = RM499,you can get around RM450

no,it doesn't come with armband

actually i thought of that too...any dealer in malaysia?

Anyone tested Sonic Gear Earpump Pure and Aura? How do they perform? Just want to listen to some opinions... Balanced armature in those phones... I actually tested them. Anyone want test can find it at lowyat Thundermatch. Frankly speaking, the Pure, despite named "Pure", it bassy, typical Sonic Gear. Didn't get to listen to it nicely. They connected it to their own source, right side of the earphone no sound... Tried the aura too, the built is bad! It won't fit nicely and fitting it wrongly, the sound is totally wrong. If it's not fit nicely, it sounds like RM20 earphone. Too bad I can't get it perfectly fit without holding my hand to push it in. The most important thing is... When I take out, the tip came off and stuck in my ear canal! What is that? My earpump 2 pun no such problem, priced RM23X got such design problem (or accessories problem). Both aura and pure are priced higher than the Feels Pro 900

I won't recommend them to anyone

If it was up to me, I'd look at the sound I like to find first. For example, do I like bass, or do I like more clarity and airiness and treble than my current setup. Next, look at your source and what can it do, what sound does it offer? Then I start looking at price, and to what extent am I willing to spend my money on. Then, I narrow down my selection within that price range.

For the headphone selection part, I ask myself a few questions. What does it have that I like/does it fit my criteria? Are there anything similar to this? Can I stretch my budget just a little bit more or are there cheaper options just as good as this? What do reputable reviewers say about them? Can I audition them (I rarely have this chance)? And the last but most important question, what can possibly go wrong if I choose this (don't like the sound, breaks within a few weeks, not good with source, doesn't sound good with favourite genre of music)?

All those makes me one very confused and undecided audiophile.
