Worth it considering the price/performance
Using my Samsung Galaxy Note 8 for an initial sound test, they are surprisingly well isolating, comfortable for my ears, and very light-weight. Nice to have some inline controls such as volume control, and the volume slider has just the right resistance, although the cable does feel a bit plastic-y and I would have liked to see a better selection of tips. Great that it comes with a decent case tho. I also tried plugging them into my Liquid Spark and MD THX amp, but found little to no improvement. These should be driven well by most any decent source.
Certainly v-shaped in signature, the sound leans a bit on the mid-bass, however tonality is quite well tuned from the hiphip and jazz I've put through it so far. Also used them to game and no complaints from people listening to me via the removable mic, other than my voice sounding a little bit hollow when compared to my Rode mic, but still quite noticeably better then the earbuds that came with my phone. Soundstage is a bit narrow, but overall for the price, I think they would be great as a lan-party headset that can double as a decent commuter earphone between play sessions.
Would recommend to a friend.
