I'll throw my thoughts in the ring. Quality is good, the magnetic on/off functionality is amazing, very comfortable and *pretty* easy to get a good seal. I wish the size large tips were larger.
In terms of sound, they were alright. Decent balance, not too much bass but not a lot either, sounded a bit thin. Wasn't super impressed tbh.
Now, here comes the really great part:
If you have viper4android or can get it, it will transform these earbuds. Most people know that v4a works magic, but I've had varying levels of success with different headphones. These have responded incredibly well, and now sound like $250 earbuds. The bass is extended and deep without being muddy, cymbal crashes are crisp and present without sibilance, and overall the soundstage is fairly good and the audio fidelity is fantastic. If you're interested in trying this out, I can leave a detailed description of my preset.
In my opinion, they're an okay value on their own but when paired with v4a they become one of the best values out there that isn't from a no-name brand.
