The relatively expensive ATH-DSR9BT headphones ($549 USD) are almost identical to Audio-Technica’s ATH-DSR7BT model ($299), which I reviewed in July 2017. They employ A-T’s new digital-transmission design, Pure Digital Drive. Instead of a traditional DAC feeding an analog amp, this method uses Trigence Semiconductor’s Dnote technology, in which, A-T explains, “the digital pulses of the chipset move the voice coil and diaphragm [of the drivers] forward and backward to create soundwaves heard by a listener.”
