I am by no means an audiophile nor do I call myself one. My experience with quality audio products is very limited and so is my vocabulary on this topic.
 
That being said I took a pair of these home to review from work as I am currently looking for new in ears and new headphones (Beyerdynamic Custom One Pros)
When I got home I plugged them into my phone and was a bit frustrated that I couldn't get them to fit at first but when I did get them to fit I was blown away. There is a good bass presence in these and they sound amazing. I used my usual music to see how they would do for my taste in music (Some rock, light metal, and some pop songs). They performed admirably across all the songs I listen to with clear and crisp vocals and not too much treble, which I like, the bass in these was also very good and not too overwhelming. Unfortunately I only got these for 1 day as I was trialing them.
The only bad thing with these earphones is they struggle slightly with highs, I don't if this was just my pair, if they need running in a it or if they are like this. The fit also isn't great for me.
