If you want longer stated earbud playback, a 20 m wireless range, and a second pair to share, choose SZHYHTIKI 2; if you need a case that can also charge a phone and provide a flashlight, choose Keenso Earbuds. For flights, I’d lean toward SZHYHTIKI 2 because its listed eight-hour earbud battery life and 20 m range make the more travel-focused case. Neither product sheet establishes active cabin-noise reduction, so don’t buy either expecting a substitute for dedicated noise-cancelling headphones.
SZHYHTIKI 2 vs Keenso Earbuds at a Glance
• SZHYHTIKI 2 strength: Two independent pairs, an LED charge display, touch controls, and listed earbud battery life of up to eight hours. Trade-off: The 120-hour playtime claim is not clearly explained, and the sheet does not establish a noise-cancelling effect for listening.
• For flights: SZHYHTIKI 2 is the more straightforward pick if you prioritize the stated battery life and longer wireless range.
• For extra case functions: Keenso makes more sense if charging a phone from the case and having a flashlight are useful to you.
• Choose SZHYHTIKI 2 if you want two pairs and more clearly specified audio and connection details.
• Choose Keenso if you value its multifunction case more than detailed information about the earbuds themselves.
SZHYHTIKI 2 is the more fully specified option. Its sheet lists Bluetooth 5.5, a wireless range of up to 20 m, 13 mm dynamic drivers, a 20 Hz–20,000 Hz frequency range, and an eight-hour average earbud battery life. It also includes two pairs that can connect independently to different signals. That makes it an unusual fit for someone who wants one pair for themselves and another for a travel companion, rather than simply a single set of earbuds.
For a flight, the case’s LED display can help you keep track of the stated charge levels, while touch controls cover playback, calls, and voice-assistant access. The product description also mentions microphones intended to reduce moderate wind noise during calls. That is a call-related feature, not evidence that the earbuds block aircraft cabin noise. The listed 20 m range is useful context, but Bluetooth range does not guarantee a particular connection experience on a crowded plane.
I’d choose SZHYHTIKI 2 if you want a pair with more concrete specifications, a second set to share, and a stated eight-hour earbud battery life. Skip it if your main goal is proven active noise cancellation for the cabin: the sheet uses noise-cancelling language, but it does not clearly describe how listening noise is reduced. The “120H” title claim also lacks enough detail to treat it as a clear single-charge earbud runtime.
Keenso’s main distinction is its multifunction charging case. The product description says the case can charge the earbuds and a phone, and that a long press on the front activates a flashlight. It also lists a 1200 mAh case battery and says it can recharge the earbuds six to eight times. That combination may appeal to someone who likes having a backup power source and light in one accessory.
The earbuds are described as using a soft composite diaphragm for stereo sound, with automatic reconnection after initial pairing. The case has an LED display for checking battery information, and the charging system uses Type-C. Those are practical conveniences, but the sheet does not provide a specific earbud playback duration or a Bluetooth version. Its listed wireless distance is approximately 10 m, shorter than the 20 m stated for SZHYHTIKI 2.

Keenso is the better match if the case’s phone-charging and flashlight functions are the features you will genuinely use. For flights, I would be cautious about treating it as the more dependable choice for long listening stretches: the case capacity and estimated number of recharges are given, but the earbuds’ own runtime is not. If battery duration per charge is central to your decision, SZHYHTIKI 2 gives you a clearer figure.
• Best for a stated earbud runtime → SZHYHTIKI 2. Its sheet lists an average battery life of eight hours; Keenso provides no earbud runtime figure.
• Best for a longer listed wireless distance → SZHYHTIKI 2. Its stated range is up to 20 m, compared with Keenso’s approximate 10 m.
• Best for sharing a spare pair → SZHYHTIKI 2. It includes two pairs that can connect independently to different signals.
• Best for charging a phone from the case → Keenso Earbuds. Its case is described as able to charge a phone as well as the earbuds.
• Best for a built-in flashlight → Keenso Earbuds. The product description says a long press on the case’s front turns it on.
• Best for clearly listed audio specifications → SZHYHTIKI 2. The sheet identifies 13 mm dynamic drivers, 32-ohm impedance, and a 20 Hz–20,000 Hz frequency range.
• Best if you want Type-C charging called out → Keenso Earbuds. Its description specifies Type-C fast charging, while the SZHYHTIKI 2 sheet does not identify a charging connector.
• Best for flights when you want a defined per-charge figure → SZHYHTIKI 2. Eight hours is listed for the earbuds, though neither sheet supplies evidence of effective cabin-noise cancellation.
I’d choose SZHYHTIKI 2 for flights because it has the clearer stated earbud runtime, the longer listed wireless range, and two pairs that can be shared. Those are more useful to me than Keenso’s unusual case extras when the main job is listening during travel.
Keenso is still the more compelling choice if phone charging and a flashlight built into the case solve a real need for you. But as a best headphone for flights or best in ear headphones for flights, I’d want a clearer runtime from Keenso and stronger evidence of cabin-noise reduction from either option. That keeps SZHYHTIKI 2 as my pick, not a claim that either is a dedicated flight-noise solution.
SZHYHTIKI 2 lists eight hours of average earbud battery life and a wireless range of up to 20 m. Keenso lists a roughly 10 m range but does not state earbud playback time, so SZHYHTIKI 2 gives a traveler more specific information to work with.
SZHYHTIKI 2’s materials mention noise cancellation and microphones that reduce moderate wind noise during calls, but they do not clearly establish active noise cancellation for listening. Keenso’s information does not specify a noise-cancelling feature. Neither sheet supports promising substantial cabin-noise reduction.
Keenso is the one to consider: its case is described as able to charge a phone and includes a flashlight. The stated case capacity is 1200 mAh, but the product information does not explain how much phone charge that provides in practice.
SZHYHTIKI 2 lists eight hours of average earbud battery life and has an LED display showing charge levels for the case and earbuds. Keenso gives a 1200 mAh case capacity and says it can recharge the earbuds six to eight times, but does not specify the earbuds’ runtime on a single charge.
