Very good sound quality. The best I've heard in terms of the panning and spatialisation of sound. Bass is prominent and on first use I was convinced I'd have to send the headphones back. I subsequently realised it was because of the proximity effect; bass is louder and more overpowering when you place headphones closer to your ears. I proceeded to rest them on my ears and it was so much better afterwards! I could hear everything rather than muddy and distorted bass.
They seem good build quality. I hope that remains the case after a few years. My last pair of AKGs broke after a year.
Overall I'm happy and would recommend to anyone looking for good quality sound at a reasonable price 😊
