The Hoppup AirDoze E51 is a true-wireless in-ear earbud set whose listings advertise Bluetooth 5.4, up to 50 hours of battery life with the case, AI environmental noise cancellation and a 40 ms low-latency mode. These are catalog and seller claims, not independently tested results. The price and warranty details below are India-market listing snapshots, so confirm them with the seller before buying.
What the AirDoze E51 listings claim
Smartprix describes the AirDoze E51 as wireless in-ear TWS earbuds. Its specification table lists the following features; the page does not establish that they have been independently measured.
| Specification | What the listing says |
|---|---|
| Bluetooth | Version 5.4; listed range of 15 m (Smartprix) |
| Battery | Up to 50 hours with the charging case (Smartprix). The listing does not state the volume, codec or usage conditions behind this figure. |
| Latency | 40 ms low-latency mode (Smartprix and retailer product copy); no test method is stated. |
| Noise handling | AI environmental noise cancellation, or AI-ENC (Smartprix and retailer product copy). |
| Water resistance | IPX4 (Smartprix). |
| Controls and calls | Microphone, touch controls, play/pause and call controls, voice assistant support and quick pairing (Smartprix). |
| Charging and audio | Type-C charging, audio sync and a listed frequency response of 20 Hz–20 kHz (Smartprix). |
AI-ENC is not the same claim as ANC
The listing specifies AI environmental noise cancellation. That wording does not establish active noise cancellation (ANC) for listening, so the E51 should not be treated as an ANC earbud on this evidence alone.
What the battery and latency figures do—and do not—tell you
The 50-hour figure is listed as battery life with the case, not as a stated single-charge runtime. No usage conditions or independent battery test are provided. Similarly, the 40 ms figure is a seller/catalog claim without a supplied measurement method; it is not enough to predict performance in every game or phone setup.

What to check before buying
- Confirm the listing is for the AirDoze E51, not a different Hoppup model, and verify the seller’s stock and final price.
- Ask the seller to confirm package contents and the warranty process for that specific listing.
- Treat 50-hour battery life, 40 ms latency, IPX4 and AI-ENC as listed claims rather than independently verified performance.
- If you need ANC, a particular runtime, or dependable game latency, look for independent tests that address that specific feature; those results are not established by the cited listings.
