Audio Technica ATH-9000 Electret Stereophones Adaptor. High quality headphones with adaptor The Audio Technica ATH-9000 comprises the headphones themselves and an adaptor to which they are connected. The reason for this arrangement is that the ATH-9000 uses electret drivers rather than the more usual dynamic devices. Such an adapter more usually signifies an electrostatic design, with the black box supplying the polarising voltage used by the electrostatic drivers. In this case, however, the black box is a step up transformer to boost the signal voltage to the level required by the relatively insensitive electret drivers. The ATH-9000 adaptor is intended to be hooked up to the speaker outputs on your amplifier and a set of rather cheesy spring clip input terminals are provided for your speaker leads. Unless your amp has two sets of speaker outputs this represents a bit of a compromise for those that listen to both loudspeakers and headphones. The headphone unit is pretty conventional looking; a polypropylene band supports the yolks and the earpads are rather mundane plastic covered items that are bound to induce sweating. It also feels quite shallow, and you don’t get the usual circumaural impression of space when wearing it. Comfort-wise it was pleasantly relaxed in its grip, and but for the warmth factor I could happily have worn it for the duration of several albums. For listening purposes I hooked the adaptor up to a Pioneer A-400. It sounded very smooth and relaxed, a bit like the fit, but with a reduced sense of spaciousness compared to some of the better dynamics in the bunch. Bass was well represented with better depth than usual and had nice drive, although like the rest of the spectrum it could have been more nimble. Overall it lacked a sense of life, which could be put down to the less exotic amplification being used to drive it, though this hasn’t been a criticism of the A-400 in the past. If you have a lively amplifier with no headphone socket but you want to get canned, then this is certainly one option, but, considering the rather high asking price, you might be able to get better results with a more conventional design.

Audio-Technica ATH-70 Headphones, Electret, like electrostatics. Bought for myself as a Birthday Present in 1989 but hardly used. I have just replaced the ear pads so they are unused. I have checked everything and everything is in working order. All leads/connections are as received when new. Sounds wonderful but domestically no longer able to keep.
