The something to hold while spinning a turntable? Pioneer’s HDJ-1500 ($209) could be that thing, if you’d give it a friggin’ chance for once. Pioneer’s new DJ Headphones are for pros, and to be clear I don’t mean prostitutes. Prostitutes are more than welcome to buy them; Pioneer is not prejudiced. Modern courtesans would especially appreciate the sound balance that the HDJ-1500 provides, and the stylish soundproof ear chamber. For the tech-savvy hookers, frequency ranges from 5 Hertz to 30,000 Hz, 32 ohm impedance, and other jargon. Not that I would know anything about prostitutes, who’s asking? But seriously, prostitution is a victimless crime.
