Hi Boom
It is only recently that I bought my first ever pair of dedicated studio headphones. I feel a bit embarrassed to admit that in *ahem* years of having a home studio set up, I have only ever used 'normal' hi-fi headphones - shameful! I think the reason that I have never really looked into it is because I have and never will do a mix using headphones, I have only ever used them for the times I can't use my monitors, like when it is 3am in the morning and I want it loud!
So I got myself a pair of Shure SRH440 headphones, and obviously I am no expert in this field (!) but I can still confidently say that I am totally happy with them. Sure, they ain't an expensive, hi-end model, but they do me fine - and they is loud!! Although I still don't do my mixes using headphones!! ?
Not sure if I can post links to products, so if this needs to be removed Mr.Moderator please do, and apologies! https://www.shure.com/en-GB/products/headphones/srh440
