• Bokexing Earbuds — biggest strength: up to 20 hours of continuous playback paired with an IP7 waterproof rating, which is the tougher of the two water-resistance ratings here.
• Bokexing Earbuds — biggest trade-off: no active noise cancellation, so nothing is actively filtering out background sound on calls or in a noisy gym.
• Generic Air31 — biggest strength: the charging case is rated for up to 80 hours of total listening, far beyond the earbuds' own 4.5-hour run time.
• Generic Air31 — biggest trade-off: each earpiece only lasts about 4.5 hours per charge, and the IPX5 rating is splash- and sweat-resistant rather than submersible.
• Who Bokexing is for: someone who wants one long, uninterrupted session and doesn't want to think about the case.
• Who Generic Air31 is for: someone who wants a comfortable all-day carry-around pair with a case that acts as a deep battery reserve, and who values call clarity.
The Bokexing Earbuds are built around endurance and durability. The headline figure is up to 20 hours of continuous playback, and that's not a case-top-up number — it's the listening time the product is specified for. That single spec reshapes how you use them. A long shift, a full day of study, a road trip, a marathon training block: you can plausibly start and finish without reaching for a charger. Very few true wireless earbuds in this class are specified that way.
The second pillar is the IP7 waterproof rating. That's a meaningful step up from splash resistance, and it's the spec that makes these a genuine sport pair. Sweat, rain, and splashes are all within the stated rating. If you run outdoors, train in a humid gym, or just want earbuds you don't have to baby, this is the number that matters most. Pair that with Bluetooth 5.3 for a stable, low-fuss connection and compatibility across both Android and iOS, and you've got a pair that works with whatever phone you already own.
Generic Air31: Who It's For
The Generic Air31 takes the opposite approach: it treats the charging case as the real battery. Each earpiece is rated for about 4.5 hours, which is modest on its own, but the case is specified at up to 80 hours. Recharge times are short too — roughly 2 hours for the earpieces and 1 hour for the case. The practical effect is that you can listen in short bursts across many days without ever feeling the charger anxiety that comes with a shallow case.
This pair also leans into calls. The data sheet lists active noise cancellation, and the product is described as offering noise cancellation for voice calls. That's the feature to care about if you take a lot of meetings or phone calls and want your voice to come through more clearly in a busy room. Comfort gets real attention too: the earpieces are angled in-ear and described as ergonomic, which matters if you wear them for long stretches. Bluetooth 5.3 is on board here as well, with a stated wireless range of up to 10 meters, and the frequency range is listed at 20 Hz to 20,000 Hz.
The trade-offs are honest ones. The 4.5-hour per-earpiece life means you're dependent on the case for anything long. The IPX5 rating handles sweat and splashes but isn't the submersible-grade protection the Bokexing pair claims. And the brand is literally listed as Generic, so this is a no-frills product with no brand story behind it. Buy it if you want a comfortable, call-friendly pair with a huge case reserve. Skip it if you want a single earbud to survive an all-day session on its own.
Side-by-Side: Which Should You Choose?
• Best for long single sessions → Bokexing Earbuds. Up to 20 hours of continuous playback beats a 4.5-hour earpiece every time.
• Best for heavy sweat and rain → Bokexing Earbuds. IP7 is the stronger waterproof rating of the two.
• Best for calls in noisy places → Generic Air31. Active noise cancellation is listed here; the Bokexing pair has none.
• Best for all-day comfort → Generic Air31. The angled in-ear, ergonomic shape is explicitly designed for long wear.
• Best for set-it-and-forget-it simplicity → Bokexing Earbuds. One long charge, no case-management habit required.
• Best for quick top-ups → Generic Air31. Roughly 2 hours for the earpieces and 1 hour for the case is a fast turnaround.
• Best for kids, teens and young adults → Generic Air31. Its stated age range is broader, while the Bokexing pair is listed for adults.
In my opinion, the Bokexing Earbuds are the pick for most people who came here looking for hifi stereo earbuds to actually use hard. Up to 20 hours of playback in a single stretch and an IP7 rating is a combination that solves two problems at once — running out of charge and worrying about water. I'd choose the Generic Air31 only if active noise cancellation for calls and a massive case reserve matter more to you than per-earbud run time. For everyone else, the Bokexing pair is the safer, more durable buy. Check the current price on Amazon before you commit, since that's the one thing specs can't tell you.
what hifi wireless earbuds
HiFi refers to high-fidelity stereo sound, and both pairs here are specified with dynamic drivers for that purpose. The Bokexing Earbuds list an impedance of 20 ohm, while the Generic Air31 lists 32 ohm and a stated frequency range of 20 Hz to 20,000 Hz. Both use Bluetooth 5.3 for a wireless connection.

what are the best hifi wireless earbuds
In my opinion, "best" depends on which spec you can't live without. Choose the Bokexing Earbuds for up to 20 hours of playback and IP7 water resistance, or the Generic Air31 for active noise cancellation on calls and an 80-hour charging case. Neither is universally better — they're built for different priorities.
Do these earbuds work with both Android and iPhone?
The Bokexing Earbuds are explicitly described as designed for both Android and iOS devices. The Generic Air31 is a Bluetooth 5.3 wireless product with no headphone jack, so it pairs wirelessly rather than by cable. Neither requires a specific phone brand.
