Pros
Pro Deep and powerful bass, detailed highs and smooth mids
The focus of the sound signature is the bass. The low frequencies have good extension and have great sub bass rumble. This makes the headphones great for pop, hip-hop, house, EDM and similar styles of music.
The highs have good detail but do not have that shimmer up top. Mids are also not too forward but are present and have a smoothness to it that makes vocals good to listen to.
Overall, these headphones are quite versatile, with bass heads most likely to be satisfied by its sound.
Pro Comes with an extensive accessory pack
It includes universal yellow foam ear tips, triple flange ear tips, single flange ear tips and standard foam tips. You also get a carrying case for the headphones. With these accessories, you will have many options in terms of in-ear comfort and seal. The carrying case should also make it much easier for you to bring these on the go.
Cons
Con Ear piece connectors can malfunction
While the cable itself is not a problem, the connectors between the cable and earpieces can be an issue. There have been a number of instances where the MMCX connection has been damaged quite easily. There are also cases where there is no electrical connection despite the cables being properly connected physically.
Con Stiff cable can cause the earpieces to get dislodged
While the thickness and stiffness of the cable helps keep it durable and tangle-resistant, it also has the drawback of moving the earpieces if the cable is moved. This can lead to the random dislodging of the earpieces, especially if you're on the move.
