Bought these for the purpose of general listening. Just needed some low priced headphones untill I can buy a better pair. I've had a positive experience with other products from t-bone (microphones) and thought that these headphones might be quite good compared to others in the price range.
The build quality seems alright, the earpeaces fit well enough, and the pouch is pretty neat as well.
My main problem with this product is that the frequency response on these is terrible for recreational listening, because the low end is super exagerated and in return, the audio sounds super muddy and is just lacking clarity.
I'll have to admit that I have not owned earphones marketed as in-ear monitors, and I can see how the boosted bass can be (and most probably is) a positive thing in order to hear the bass when you're on stage and everything is super loud.
For general listening - I would consider something else, unless you think that more bass equals better earphones.
