I adore these so much and am so glad that i made the decision to get them! The clarity they offer is incredible and they make live music sound so much better while protecting the ears. They're also incredibly comfortable and secure in a way no universal solution comes close to. I had my impressions done that the ACS office in King's Cross and was treated wonderfully the entire time, and the gentleman very kindly explained every step and answered all of my questions. Easily one of the best investments i've made, I highly recommend!

I needed some replacements for my old Ultimate Ears 4 that had broken. Extremely happy with the fit and overall sound quality. As they are made of silicon as opposed to acrylic, the fit is brilliant. I currently play guitar and bass and they have coped perfectly. Would happily recommend.

Excellent customer service. There was a complication due to impending holiday and an unsuccessful impression but the matter was resolved with speed, pragmatism and very professional

Fantastic service and quick turnaround, recommended to me from artists I tour with, 10/10 all around

Expensive but excellent sound quality and fit
