Thatâs something thatâs up to the listener to decide lol, also it depends on what you drive them with too. All I will say is that imo the sound justifies the cost, at least it did for me, but I canât really give an arbitrary numbers since it can vary from person to person.
So I would agree the timbre of the clear is a tad metallic compared to something like an hd600, but imo more than usable. I do think the ndh20 has a bit better timbre, but really I think the benefits of the clear outweigh the downsides in this case. Also their timbre is affected by whatâs driving them, one of the reasons why I like the rnhp with it is because it really gives it a more natural timbre (and more natural overall), going out of your interface it would most likely be lacking for timbre for you (again itâs amp picky). No headphones are really going to be true to the source is what Iâve found out. My main headphones I use for mastering are a warwick aperio system, and I would say they are great but still not âtrue to the sourceâ imo.
I think if you get a clear, itâs good to have a timbre check headphone like an hd600 or something, the ndh20 would work well for this too. For me I go through a rotation of headphones during mastering so I can get good references on how things sound and make sure a single headphone isnât skewing my work
