Truly blown away by the difference these make.

I’m writing this after gigging with my custom in ears for the first time last night and am frankly blown away. It’s mad to think I went all these years without them! Just the overall clarity and balance in my ears and how good the fit is. Thanks to DCA for going above and beyond to make sure I had every question answered and every type of in ears tried out to make sure I get what is most suitable for me. No push to get the most expensive thing, no ‘hurry up and give me your money’, just genuine people, passionate about what they do.
