That obviously makes use while exercising challening. This is really the overarching problem I experienced with the BackBeat Go – the earbuds either slowly slide out of my ear canals, or movement of my head perturbs them, and I lose the seal and soundstage entirely. Without a good seal, I found suppression less than ideal and bass and mids very underdriven. Given the small size of the drivers, I’d say the BackBeat Go audio quality is actually surprisingly decent. That said, I’d characterize the experience as more than adequate for casual listening. Mids and bass are decent, though somewhat lacking compared to either of my usual go-to IEMs (Shure SE115 or SE 535). With a good seal, I found the listening experience surprisingly enjoyable.
Most of my complaints about the BackBeat Go sound quality boil down to the lack of a good seal between the earbud’s small rubber sleeve and the ear canal. I would say that sound quality on the BackBeat Go is more gated by its earphone performance and construction than the use of SBC codec. I’ve never been dissatisfied with A2DP at the maximum bitpool on any device, though at the same time there is a perceptible difference between A2DP and a good analog output. On the whole, sound quality is nothing to be terribly excited about, but is good enough for casual listening.
Plantronics backbeat go 3 Bluetooth#
Inside each earbud is a ton of volume dedicated to battery and the Bluetooth controller, and relatively little volume dedicated to the actual 6mm neodymium drivers. It’s hard to be overly critical about the audio performance of the BackBeat Gos since they’re so volume constrained. It’s possible they’re citing that number based on the earbuds being driven at a lower volume level, though 70% is where I often listened on the BackBeat Gos partially because of the lack of great isolation. I ran the test twice, and wound up with an average run time of 3.4 hours, which is just short of the cited 4 hours for A2DP, but relatively close. In this manner it was possible to easily measure how long until the BackBeat Go battery died. I then placed the earbuds next to the One S (so there was good Bluetooth signal) with one of the earbuds inside a bag with a microphone. To do this, I paired the earphones with an HTC One S and played an album on repeat, with the volume on the earphones set to 70%. Of course, I’m not satisfied with just citing manufacturer specs for battery life, and went ahead and measured the BackBeat Go audio playback time.
