BenQ treVolo S – Portable Electrostatic Bluetooth Speaker REVIEW – Redefining sound!

Welcome to my review of the BenQ treVolo S Portable Electrostatic Bluetooth Speaker. The BenQ treVolo S retails for £149 / $199.

It is the world’s smallest portable Bluetooth speaker featuring Electrostatic Speaker Technology. Electrostatic speakers deliver superb clarity and accuracy. The vertical dispersion of the entire thin-film diaphragm offers bi-directional sound projection for a more detailed audio performance and accurate delivery of natural, crisp and clear sounds. The dual amplifiers and dual woofers finish the sound off.

After removing the treVolo S from its packaging, I was pleasantly surprised at the solid construction. The electrostatic speakers open out from the sides of the speaker (watch video to fully appreciate the design, operation and sound)

There are a few ways to connect to the speaker. NFC for quick pairing, standard bluetooth or via USB for the highest quality sound. There is an android and iOS app available to assist with linking another speaker together and well as quickly toggling between standard and non distorted 3D sound.

As the treVolo S uses electrostatic speaker technology, (this is normally found in high-end speaker systems), this means it has a really low distortion rate that is only one-tenth of the rate of conventional speakers. There is also no cabinet resonance. One of the key sound characteristics of electrostatic speakers, is the natural and spacious sound. Listening to a variety of genres with the treVolo S and this sound quality is obvious from the get go and a joy to listen to.

Genres auditioned. Classical, jazz, blues, rock and pop. Listening to some of my favourite classical pieces, the treVolo S has an wonderful transparency and emotion. Clear vocals and mid range with just the right amount of bass. Female jazz singers sounded superb. With rock and pop, once gain great clarity with just the right amount of bass. These do not have a V shaped sound with over compensated bass. The treVolo S is designed to play high quality lossless music, yet even via bluetooth its reproduction is beautiful.

As a tip for placement, do not push these back against a wall. Electrostatic speakers emit sound from both sides, so leave some space behind and place speakers at ear level when listening.
