The frequency response measurement shows surprisingly little deep bass response below the big peak centered at 75 Hz. But it’s obvious from that peak that the TTR’s driver/enclosure has a strong bass resonance, which is why it sounded somewhat boomy to us. The mids and treble seem, from this measurement, to be fairly well in balance with the overall amount of bass; it’s probably just that strong resonance that makes this headphone sound overly bassy. I’d like to hear this headphone with more work put into the bass tuning, because it seems to me that a little tweaking might make it a Bose-beater.
