Now that's a V-shaped FR on that B7...or is it a W? Anyway, it sounds like what I'm hearing with the L-85.
That graph is meaningless. Many companies that sell headphones with those beryllium drivers use the same graph. It is propably a graph offered by the company that makes the BE drivers. Graph is always the same on aliexpress. It doesn't matter if it is closed or open headphone etc... so pay no attention to that graph.
On some degree I can agree to that though. Msur n550's I have are definately very V shaped as stock but the is more to it. Beats etc are V-shaped but so is TH900. N550's are definately more in the audiophile class.
Sure, it is irrelevant, when were talking about lasmex l85. The drivers are definately different. I just wanted to point out that the graph has nothing to do with lasmex and hardly anything to do with most of those chinese beryllum driver headphones, because nobody knows in which housing and with what pads etc were those driver measurements made.
