"I currently own the S4X and gotta say this is one of the best headphones I have ever used. The Build quality is better than most, you can easily replace the parts yourself and the smell of the wood is heavenly. The sound is clean and crisp and not at all hyped like some headphone brands. The fit is brilliant they don't hang and cause any pain from extended mixing session and the open and honest sound from these cans has improved my mixes 10 fold. I would personally recommend these headphones not only for the price point but the sheer quality. The team at OLLO has taken what was learned from the previous headphones and has made a work of art. You will just have to hear it to believe it."
