Very good headphones!
It has an additional FY bass .. never heard similar and ears vibrate .. totally awesome!
It can be used 10 hours at full battery and takes 3 hours to charge to 100%.
BUT here comes the negative part of this product.
Highs and vowels are very weak, the bass is extremely high and full-bodied.
But must Equalizer app on your phone to increase both sound, vocals and treble.
After I did this experience amazing!
This is worth the price of 1167kr, product with purchased Spaceworld Soundgarden when the shop was closed down in my town.
Will say that I'm never going to wear earplugs or other types of low budget headphones again after this experience. :-D
