The TW-20 is the pair for the half of listening that happens away from a desk. Sealed in-ear fit, three pairs of silicone tips in the box, and a case small enough to forget about in a coat pocket.
Codecs and pairing
Bluetooth 5.3 with SBC, AAC and aptX Adaptive. Which one you get depends on your phone, not on the earbud, an iPhone will use AAC and most recent Android handsets will negotiate aptX Adaptive. Multipoint holds two devices at once, so a laptop call interrupts a phone without re-pairing.
Battery
Seven hours a charge with noise cancelling off, roughly five and a half with it on, and three further charges in the case. Those are the manufacturer’s figures at 50% volume; your own will depend on volume and codec.
Noise cancelling
Feedforward and feedback microphones with a transparency mode on the same control. We publish no isolation figure in decibels because that needs a measured test report. [Client to confirm measured attenuation if a test report is available.]
