GOBOULT Z40 v2.0 TWS Earbuds with Bluetooth 5.4, 70 Hours Playback

Pull the Z40 v2.0 out of the case and the first thing you notice is how quickly it grabs the connection — Bluetooth 5.4 doing its job without the usual half-second lag you brace for. Slip them in, and the fit settles with barely any prodding.

Sound That Has Some Weight to It

The 13mm dynamic drivers paired with Boom X™ Technology push out bass that actually has body to it, not just a bump in the low end for show. Bass-heavy tracks land with a satisfying thump, and mids don’t get buried in the process — decent for casual listening, gym sessions, or just background noise while working.

Calls and Gaming, Handled Quietly

On calls, the Quad Mic Environmental Noise Cancellation (ENC) trims away a fair bit of surrounding chatter, so your voice comes through cleaner than you’d expect at this price. Switch over to a mobile game and the 45ms low-latency mode keeps the audio glued to on-screen action — you stop noticing the delay, which is really the point.

Battery Life You Stop Worrying About

Playback stretches to up to 70 hours total with the case, so charging becomes a once-a-week chore rather than a daily one. Forgot to charge overnight? A quick 10-minute top-up through the Type-C port buys you roughly 120 minutes of playback — enough to get through a commute or a workout.

Built for Daily Wear

The IPX5 water-resistant shell shrugs off sweat and light drizzle, and touch controls respond with a soft, reliable tap rather than repeated jabbing. Works fine across Android and iOS, with Siri and Google Assistant support baked in. Available in four colorways, the Z40 v2.0 stays competitively positioned for what it offers.
