Hi all. I recently started a technology blog called AxiosTech. Amongst other things, I'm going to be writing articles about audio and headphones, so I thought I'd post here in case anyone's interested. So far I've written one post, mainly aimed at beginners, and its here...

I currently use a Creative X-Fi HD USB DAC/Amp, which takes a USB input and is also USB powered. I do not have a wall power socket near my setup, so what would my upgrade options be? Would I have to go for a portable amp? I know the O2 Amp+DAC Combo has USB power. Also my current Amp/DAC can...

I'm just selling my MDR 1R and am in two minds about the above cans. I listen to exclusively EDM and Bass music, and like a fair amount of it. For me the 1Rs weren't quite there on the bass front. From what I've heard the venerable HD25s might be a viable option, and I'm nearly sold on them...

I have a Nexus 4 and would like to use it sometimes with my Fiio E11, but I don't want to use the included silicone bands as they are too tight and obscure the screen. What else can I use?

I have a nexus 4 and was wondering if an amp will improve its headphone out. I would consider a DAC if there was some solution that allows for use without an external power supply. I am rooted as well.

I have a DT990 Pro 250 and I am using it through my Creative X-fi HD USB amp and DAC. I cannot really hear much of a difference using it with or without the amp. Will buying one of the above listed amps help?

I recently bought the Beyerdynamic DT990 Pro 250 headphones and a Creative XFi-HD USB. I know these headphones are relatively hard to drive, but when I compare them amped and unamped, all I really hear is a slightly tamed treble in comparison. Am I missing something?

I'm in the UK and both are available for the same price on Amazon UK. Which are better in terms of build quality and sound? I listen to exclusively House, Dub step, Drum and Bass and Trance, so I like a good strong but not overpowering bass response.

I really want to get these IEMs since they have a good sound for their price, but there's one problem. Amazon UK only has them used, or imported from Japan, and they are only available marketplace on Amazon US as well. Should I just get them off eBay, or used?

I have seen a lot of people here on Head-Fi recommend both these IEMs, and I don't know which to get. I listen to electronic music like house, dubstep, drum and bass etc. Any thoughts?

I was perusing some high end headphone reviews(LCD3, HD800, T1) and none of them make reference to electronic tracks. They say that this jazz song sounds good, that rock band's music has good treble etc, but no house, dubstep, drum and bass, trance and so forth. Why?

This is my first review, so go easy guys! I have been using the Sony XBA 1 IEMs for about 6 months, now, about a month ago I picked up some of the aforementioned comply foam tips. Without them, the bass is accurate, but a little light, and the treble is very pronounced, bordering on harsh...
