BenQ treVolo Speakers

The BenQ treVolo portable electrostatic speaker faithfully reproduces audio streamed from any Bluetooth® source device: smartphone, tablet or PC. The sonic performance in the medium- and high-frequency range is particularly refined. Unlike conventional magnetic speaker technology, this electrostatic speaker’s entire thin-film diaphragm is designed to project bi-directional sound from a large surface area from every angle. The treVolo features aptX™ to decode Bluetooth stereo audio data with minimal latency.
