Looking for affordable monitoring headphones ("cans") for studio tracking, I compared Superlux HD660, Superlux HD665, t.bone HD 990D, Vic Firth SiH2 and Beyerdynamic DT-770M to each other and to my DT-770 pro 80. I know, not a really fair reference, but my idea was to seek for a series of cans that would not cost more, preferably less than my DT-770 and still would have proper, useful sound quality. From the types selected, you can guess that acoustic isolation was also a desirable feature, to prevent the sound from the cans bleeding into e.g. a singer's mic and thus saving me time cleaning up tracks from this bleed. I will review all of the models mentioned, each in their own product page. Here we go for the t.bone HD 990D.
The sound is quite dull over all of the spectrum. Although recommended by Thomann for drummers, because of it's claimed attenuation of 22dB, to me, it's isolation does not really differ from my DT-770pro or my good old Sennheiser HD250 linear II. Finally, it is not the most comfortable to wear of the models compared. But it is not an expensive pair of cans either, explaining the title of this review ;-) Anyway, not my choice in this quest, as you may have guessed.
