[QUOTE="David Morison, post: 83369, member: 2076"] Re: New speaker tech.. *Graphene* I have no idea how they can claim that the graphene is "comparable to or better than" the Sennheisers. According to that graph, the Senn's are within 10dB of their peak level between approx 90Hz and 7k5Hz. Not great by professional standards, but for an £8.99 pair of consumer units, I guess that's to be expected. The graphene only manages to stay within 10dB of peak between approx 70Hz and 600Hz - that is at least a decade narrower useable bandwidth. Their claim just doesn't bear any resemblance to the graphs at all. [/QUOTE]
