If you want the earbuds that keep going long after a single workout and can shrug off a full downpour, choose Jectse Earbuds; if you need a newer connection standard, multiple ear-tip sizes for a locked-in fit, and a lighter case to carry, choose SUNGOOYUE Earbuds Earbuds Heavy. Both are IPX7-rated sports earbuds, so the real decision comes down to battery strategy, fit options and connection version — not waterproofing, which they share.
• Jectse Earbuds — biggest strength: a 1200mAh charging case that the brand rates for 24 hours of use, plus IPX7 sweat and rain protection.
• Jectse Earbuds — biggest trade-off: the earbuds themselves run about 4 hours of talk time per charge, and the charging case itself is not waterproof.
• SUNGOOYUE Earbuds Earbuds Heavy — biggest strength: version 5.3 connectivity and four pairs of replacement earplugs for a customized, secure fit.
• SUNGOOYUE Earbuds Earbuds Heavy — biggest trade-off: a 200mAh case rated for 5–6 hours of playback, so total listening time between charges is far shorter.
• Who each pick is for: Jectse suits long-session users who want the case to carry the battery load; SUNGOOYUE suits buyers who prioritize a newer connection version and fit flexibility.
The Jectse Earbuds make their case on endurance and weather resistance. The headline feature is the charging case: a built-in 1200mAh lithium battery that the spec sheet describes as good for 24 hours of use, with the earbuds topping themselves up automatically every time you drop them back in. Each earbud carries its own 50mAh battery and is rated for roughly 4 hours of talking time, charging in about 1.5 hours. So the workflow is simple — short bursts in the ears, long reserves in the case.
Water is handled with an IPX7 rating, which the brand frames as protection from sweat and rain. For runners, gym-goers and anyone who trains outdoors in unpredictable weather, that's the important line. One caveat the sheet is honest about: the charging case is not waterproof, so you shouldn't dunk the whole kit or leave it sitting in a puddle. The earbuds are the protected part, not the case.
SUNGOOYUE Earbuds Earbuds Heavy: Who It's For
The SUNGOOYUE Earbuds Earbuds Heavy lean into fit and a more current connection. Version 5.3 is the newer standard here, and the brand pairs it with a "heavy bass" tuning aimed at workout energy. Like its rival, it carries an IPX7 rating described as sweat- and rainproof, so gym sessions and rainy runs are covered on the earbud side. The earbuds connect to each other straight out of the charging case, which keeps pairing quick.
The fit story is the standout. SUNGOOYUE includes four replacement earplugs, so you can size the tips to your ears rather than accepting whatever comes fitted. For anyone who has ever had an earbud work loose mid-sprint, that's a genuine advantage — a secure seal also helps bass response and passive noise blocking. The earbuds themselves use 2 x 50mAh batteries, and the charging case holds 200mAh, rated for 5–6 hours of continuous playback on a single charge, with a 1–2 hour recharge time.
The trade-off is obvious once you line the numbers up: a 200mAh case simply cannot match a 1200mAh one. If you're the type who charges once and forgets about it for days, this is not that product. Transmission distance is around 10 meters, same as the Jectse, and the sheet lists compatibility with laptops, phones, tablets and digital assistants. I recommend it for buyers who want a newer Bluetooth version and customizable tips and don't mind charging more often.
• Best for total battery life → Jectse Earbuds. A 1200mAh case rated for 24 hours versus a 200mAh case rated for 5–6 hours is not close.
• Best for fit customization → SUNGOOYUE Earbuds Earbuds Heavy. Four replacement earplugs give you sizing options the Jectse sheet doesn't list.
• Best for newest connection standard → SUNGOOYUE Earbuds Earbuds Heavy. Version 5.3 beats version 5.1 on paper.
• Best for long calls or all-day listening → Jectse Earbuds. Roughly 4 hours of talk time per earbud charge, backed by a case that keeps refilling them.
• Best for bass-forward workouts → SUNGOOYUE Earbuds Earbuds Heavy. Its "heavy bass" tuning and secure-tip design target exactly that use.
• Best for travel and forgetting your charger → Jectse Earbuds. The bigger case reserve means fewer top-ups on trips.
• Best for quick setup and light carry → SUNGOOYUE Earbuds Earbuds Heavy. Earbuds connect straight from the case, and the smaller 200mAh case is the lighter thing to pocket.
• Waterproofing → a tie. Both are IPX7 on the earbuds, so neither wins that category.
In my opinion, the Jectse Earbuds are the better buy for most people, and the reason is purely practical: the 1200mAh case rated for 24 hours solves the single most annoying problem with true wireless earbuds — running out of charge at the worst moment. The 4-hour earbud rating is modest on its own, but the case makes it irrelevant. The IPX7 rating covers sweat and rain, which is what an active buyer actually needs.
If a newer Bluetooth version and four ear-tip sizes matter more to you than endurance, the SUNGOOYUE Earbuds Earbuds Heavy is a reasonable alternative, and you'll charge it more often as a result. Check the current price on Amazon before deciding, since that's the one variable neither spec sheet settles.
are headphones waterproof
Truly waterproof headphones are rare — most, including both of these, are water-resistant rather than fully submersible. The Jectse Earbuds and the SUNGOOYUE Earbuds Earbuds Heavy both carry an IPX7 rating, which means the earbuds are protected from sweat and rain. Note that the Jectse charging case is specifically listed as not waterproof, so keep the case dry.
are headphones water resistant
Yes, many sports headphones are water resistant, and both models here qualify. IPX7 is a high water-resistance rating for the earbuds themselves, covering sweat during workouts and rain during outdoor runs. On the Jectse side, that protection applies to the earbuds, not the charging case.
The Jectse Earbuds, by a wide margin. Its charging case holds a 1200mAh battery rated for 24 hours of use, while the SUNGOOYUE case holds 200mAh and is rated for 5–6 hours of playback. Both earbuds use 2 x 50mAh batteries, and both charge in roughly 1–2 hours.
Both are built for it. The SUNGOOYUE Earbuds Earbuds Heavy adds four replacement earplugs for a more customized, secure fit, which helps during high-movement training, and its heavy bass tuning suits energetic music. The Jectse Earbuds counter with the longer-lasting case, so you're less likely to run out of power mid-week. Pick based on whether fit options or endurance matters more to you.
