Pros: Good bass, very comfortable and lightweight.
Cons: Requires a good burn in, poor build quality.
However, I can still remember the time I took these headphones out of the box, they sounded awful. Literally awful. The bass sounded distorted, the mids are non existent and the highs sounded so bad that my ears hurt. I decided to give them a burn in for around 24 hours and oh my god the sound changed so much. The bass sounded much clearer and punchy, I can finally hear some mids and the treble doesn't try to make me go deaf anymore. As it turns out, after around 48 hours of burn in, these pair of headphpnes sound pretty phenomenal fpr their price.
Sadly, having a good burn in isn't the biggest con that might actually hold you back from purchasing these decent pair of headphones. The biggest con is indeed related to how poorly built these headphones are. Made out of plastic, they are very lightweight but sadly they are not very robust, even they do look like they are. After a few months of listening, I started to hear static in my music which at first I thought it was my PC's headphone jack's issue but as it turns out it's the headphones. I still use them sometimes but the static is just irritating and it ruins my listening expetience in a way.
As a conclusion, if you are someone who listens to dubstep, EDM or anything bassy, and is going on a tight budget and wants something that looks cool and "expensive", these are what you might be looking for. However, if your budget is a bit looser, I would recommend that you go with the FX1X instead. The sound is better and so is the build quality and I would definetly suggest ypu taking a look at that first.
