Iam using this since a month and heres my review for you guys.
First, I will start with the pros and then I will tell the cons. and Im a ex Sennheiser user thats why I dont like these earphones. But Im not saying they are bad. They are good earphones but just for average listeners. And dont think that I dont have a good music player! I have tested them in iPhone 6s, Samsung Galaxy note 3, Samsung Galaxy j7, apple iPod, Samsung galaxy s7 edge.
Pros
Clear sound.
Looks good ( not so much)
Gold plated jack
Cons
Too low volume
Theres just a tiny little bass
Built quality is not at all good, dont know when it can break.
On its box, its stated that they are tangle free but they are not.
So here my review on these. If you are thinking of buying earphones under 1000 then go for Sennheiser cx 180.
