If you want earbuds built around connecting to airplane entertainment and other aux devices, choose Avantree Sky Ace; if you need workout-ready earbuds with a long combined battery claim, choose sajawass Earbuds Headphones. For college students, I’d lean toward Avantree for travel and device flexibility, or sajawass for exercise and fewer charging stops.
Avantree Sky Ace vs sajawass Earbuds Headphones at a Glance
• Avantree Sky Ace strength: Its transmitter connects the earbuds to airplane entertainment and other aux audio devices; trade-off: the snug fit is designed for medium-to-large ears and may not suit smaller ears or loose-fit preferences.
• sajawass Earbuds Headphones strength: Ear hooks, three tip sizes, IPX7 protection, and up to 75 hours total playtime with the case; trade-off: it does not include an aux connection or airplane adapter.
• Sky Ace sound and calls: AptX Adaptive, tuned dynamic drivers, and four cVc 8.0 microphones; sajawass sound and calls: 13 mm drivers and ENC noise reduction for calls.
• Sky Ace battery: Up to 10.5 hours; sajawass battery: over eight hours per charge, with up to 75 hours total using the case.
• Pick Sky Ace if travel, aux-device compatibility, and noise isolation are your priorities.
• Pick sajawass if workout stability, water protection, and extended case-supported listening matter more.
Sky Ace stands out for the included relay transmitter. Plug it into an aux audio output, such as an airplane entertainment system, and it can send that sound wirelessly to the earbuds. The transmitter can also work with other aux-equipped devices, including computers, gym equipment, Nintendo, and PS5. That makes it a more flexible choice when the audio source does not offer the Bluetooth connection you want.

For a college student, that flexibility can be useful across travel, a computer setup, or compatible gaming equipment. The transmitter and earbuds can also be used separately, and the transmitter can connect to an additional pair of headphones for shared listening. The earbuds have touch controls, Bluetooth 5.3, and a stated wireless range of up to 10 meters. Their battery life is listed at 10.5 hours.
The fit deserves careful thought. Sky Ace is intended for medium-to-large ears and uses tips and fins to make a secure seal that helps block outside sound. That design could suit flights or other noisy settings, but it may be uncomfortable if your ears are smaller or you prefer earbuds that sit loosely. The noise control is described as sound isolation, so I would not treat it as a promise of active noise cancellation. If you want ear hooks and explicit water protection for workouts, sajawass is the more relevant option.
sajawass is the more sport-oriented pair. Its lightweight TPE ear hooks are designed to help the earbuds stay in place, while three tip sizes let you adjust the in-ear fit. The product lists IPX7 waterproof protection, making it the clearer fit for sweaty workouts or situations where the earbuds might get wet. That protection claim does not make them an airplane-adapter solution, though: they connect over Bluetooth and have no headphone jack.
Battery capacity is a major part of the pitch. The earbuds are specified for over eight hours of playtime on one charge, with up to 75 hours total when the charging case is included. A digital display shows the battery information for the earbuds and case, and the stated charging time is 1.5 hours using Type-C. Those details may appeal to a student who wants to keep a pair in a backpack for classes and workouts without frequently checking the case blindly.
The trade-off is that sajawass does not provide Sky Ace’s transmitter for airplane entertainment or aux-equipped devices. Its stated compatibility is with Bluetooth audio players such as phones and tablets. The product lists Bluetooth 5.4, a 10-meter range, 13 mm dynamic drivers, and ENC noise reduction for calls. If your main aim is connecting to a computer or console through an aux output, Sky Ace has the more directly relevant feature set. If your routine centers on exercise and Bluetooth listening, sajawass makes more sense.
• Best for airplane entertainment → Avantree Sky Ace. Its relay transmitter is designed to connect to an aux audio output and send the sound to the earbuds.
• Best for aux-equipped gaming or gym devices → Avantree Sky Ace. The transmitter is listed for use with aux devices, including Nintendo, PS5, gym equipment, and computers.
• Best for workouts where a secure ear hook matters → sajawass Earbuds Headphones. Its TPE hooks are designed to help keep the earbuds in place.
• Best for water protection → sajawass Earbuds Headphones. It lists IPX7 waterproof protection; Sky Ace’s supplied information does not state a water-protection rating.
• Best for stated single-charge listening time → Avantree Sky Ace. Its battery life is listed at 10.5 hours, compared with over eight hours for sajawass.
• Best for total listening time with the case → sajawass Earbuds Headphones. The stated total is up to 75 hours, though that figure includes the charging case.
• Best for a smaller-ear fit preference → Consider sajawass first. Sky Ace specifically targets medium-to-large ears, while sajawass provides three tip sizes; neither specification guarantees comfort for every ear.
• Best for calls based on listed microphone features → Avantree Sky Ace. It specifies four cVc 8.0 environmental noise-canceling microphones, while sajawass lists a microphone with ENC noise reduction.
The gaming comparison needs one distinction: neither product is described as an over-ear headset. Sky Ace’s aux transmitter makes it the more adaptable of these two for compatible gaming gear, but it remains an in-ear earbud set. If you are searching for the best gaming headphones for college students and mean a dedicated over-ear headset, neither of these is that form factor. For the best in ear earbuds for college students, the decision is more useful: Sky Ace for aux connectivity, sajawass for workouts and case-supported battery life. And if your search is specifically for the best over ear headphones for college students, look beyond both.
My Verdict
I would choose Avantree Sky Ace for a student who travels, uses aux-equipped devices, or wants one set that can bridge Bluetooth earbuds and a transmitter. The 10.5-hour battery figure and airplane-audio feature make it the more versatile pick for that mix of situations.
No. “Sony earbuds LS900N” is a separate search phrase, while the two products compared here are Avantree Sky Ace and sajawass Earbuds Headphones. Their features should not be treated as Sony specifications.
Avantree Sky Ace is the more suitable option for airplane entertainment because it includes a transmitter intended to connect to an aux audio output. sajawass connects to Bluetooth audio players and does not list an airplane adapter.
sajawass is the clearer workout choice based on its ear hooks and stated IPX7 protection. Sky Ace also describes a secure fit for workouts, but its supplied specifications do not include a water-protection rating.
It depends on whether you mean one charge or all listening supported by the case. Sky Ace lists 10.5 hours, while sajawass lists over eight hours per charge and up to 75 hours total with its case.
