Summary
A budget true wireless earbud with active noise cancellation, Bluetooth 5.4 and a claimed 10-hour battery. The one thing to check before buying: no independent test or owner discussion of this exact model could be found, so every spec is unverified.
Strengths
- Bluetooth 5.4 and IPX5 water resistance on paper.
- Claimed 10 hours per charge, 40 hours with the case.
- Light at 5.1 g per earpiece.
- 32 EQ presets in the companion app.
- Active noise cancellation is included.
Weaknesses
- No independent test or professional review of this exact model could be found; RTINGS, Tom’s Guide, PCMag, Wirecutter, SoundGuys and CNET returned nothing.
- No owner discussions could be read, so reliability and real-world battery life are unknown.
- The manufacturer’s own product page was inaccessible, so even the basic specs are unconfirmed.
- Two different domains claim to be the official TOZO store, which raises a brand-control question.
- No warranty information is available for the US market.

Full research notes and sources
What the specs say
On paper, the 40H 5.4 sits in the budget-to-mid tier of true wireless earbuds: Bluetooth 5.4, IPX5 water resistance, active noise cancellation, 32 EQ presets in the app, and a claimed 10 hours per charge with 40 hours total from the case. Each earpiece weighs 5.1 g. These figures come from the product identity document supplied with the research task. The manufacturer’s product page at tozostore.com was rate-limited throughout the research session and could not be read, so none of these numbers has been confirmed by the manufacturer or an independent source.
The evidence gap
No instrumented test, professional review or owner discussion of the exact TOZO 40H 5.4 could be accessed. RTINGS returns a 404 for the model, and Tom’s Guide, PCMag, Wirecutter, SoundGuys and CNET either have no exact-model page or could not be reached. Reddit blocked automated access during the session. That means sound quality, ANC effectiveness, microphone performance, comfort, real-world battery life and reliability are all unknown. Treat the spec sheet as unverified.
Where to buy
The audio brand operates at tozostore.com, confirmed as the official store during research. A second domain, tozoglobal.shop, also claims to be an official TOZO store, and it is unclear which is the authorized US storefront. Note that tozo.com is a space tourism company with no relation to the earbuds. No price data from any non-Amazon source could be obtained, so this review makes no value claim.
Is it worth it?
Not enough evidence exists to say. The on-paper specs sit in the budget-to-mid tier, but with no independent test, no owner feedback and no confirmed manufacturer page, a purchasing recommendation would be guesswork. If you are considering this model, seek out independent measurements and owner reports first.
