If you want secure workout earbuds with up to 16 hours of playback and IPX7 protection for study breaks, choose JOYWISE 5.3; if you need sleep-focused earbuds with active noise cancellation and a 48-hour total battery claim, choose Ertuly T33. For study, I’d pick the Ertuly T33 when blocking nearby noise matters most, while the JOYWISE 5.3 makes more sense if you want a sport-style fit and longer playback between charges.
• JOYWISE 5.3 strength: Adjustable ear hooks, physical button controls, IPX7 water protection, and up to 16 hours of playback. Trade-off: It lacks the T33’s active noise-cancelling and sleep-specific features.
• Ertuly T33 strength: Hybrid ANC, a sleep mode, and up to 48 hours total playback with the charging case. Trade-off: Each charge is listed for up to 8 hours, and its IPX6 protection is below the JOYWISE rating.
• JOYWISE 5.3 is for listeners who want a secure sports-earbud design for exercise, calls, and everyday listening.
• Ertuly T33 is for people who want compact earbuds for sleep, travel, or study sessions where noise control is useful.
The JOYWISE 5.3 has an in-ear design with ergonomic earpieces and adjustable ear hooks intended to keep the earbuds secure during movement. That makes it a practical match for workouts, walks, and study breaks when you want your earbuds to stay put. Bluetooth 5.3 provides wireless connectivity, while the listed range is up to 33 feet. Button controls handle volume, track changes, and calls without requiring touch gestures.
For longer stretches away from a charger, JOYWISE lists up to 16 hours of continuous playback. Its battery charge time is listed as two hours, and the product information describes a USB-C charging connection. The IPX7 rating is another point in its favor for sweat-heavy exercise or rainy outdoor use. For calls, the product information describes clear-call performance, but there’s no active noise-cancelling system listed. Its noise control is passive, so buyers seeking electronic noise reduction should look closely at the T33 instead.
This is the more straightforward pick if you want sports earbuds that can also serve for studying, listening to music, and taking calls. The fit features are geared toward staying secure, not toward lying comfortably on your side. Who should skip it: Skip the JOYWISE 5.3 if sleep comfort, active noise cancellation, or an all-night low-profile design is your priority.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-22 · 7 min read · Independent comparison
The Ertuly T33 is designed around sleep and comfort. Its compact earbuds are described as lightweight, at approximately 3 grams, and shaped with side sleepers in mind. The listed sleep mode mutes alerts and helps prevent accidental touch inputs, while a four-tap control activates it. That gives the T33 a more specific use case than a standard sports earbud: it is built for settling in with audio, resting, or traveling as well as listening during the day.
Its hybrid ANC is claimed to reduce up to 98% of disruptive noise, and a triple tap switches between ANC and Transparency Mode. The claim is a product specification, not a promise that every sound or environment will be blocked. For calls, the T33 uses ENC microphones described as filtering background noise. It also supports using one earbud independently or both together, which can be handy when you want one ear free. Bluetooth 6.0 connectivity is listed with a range of up to 10 meters.
Battery figures need a little context: the T33 is listed for up to 8 hours per charge, with the case extending total playback to up to 48 hours. The case has an LED battery indicator, and the stated recharge time is 1.5 hours via USB-C. Its IPX6 rating is described as sweat-resistant, but it is below JOYWISE’s IPX7 rating. Who should skip it: Skip the T33 if you want the longer stated playback time from a single charge or prioritize the higher water-protection rating.
• Best for a secure fit during workouts → JOYWISE 5.3. Its adjustable ear hooks and sports-oriented design are intended to hold the earbuds in place during movement.
• Best for sleep and side-sleeping use → Ertuly T33. The compact, lightweight shape and sleep mode are specifically aimed at overnight comfort and fewer accidental interruptions.
• Best for active noise control → Ertuly T33. It lists hybrid ANC and a Transparency Mode; JOYWISE lists passive noise control instead.
• Best for longer playback between charges → JOYWISE 5.3. It is listed for up to 16 hours continuously, compared with up to 8 hours per T33 charge.
• Best for total playback with the case → Ertuly T33. Its up-to-48-hour figure includes the charging case, so it is not a like-for-like comparison with JOYWISE’s continuous playback figure.
• Best for sweat and water protection on paper → JOYWISE 5.3. Its IPX7 rating is higher than the T33’s IPX6 rating; neither rating should be treated as permission to ignore care instructions.
• Best for physical controls → JOYWISE 5.3. Its push buttons are suited to direct volume and track adjustments, while the T33 uses touch controls.
• Best for using one earbud at a time → Ertuly T33. Its listed single- and dual-earbud modes offer flexibility for calls or listening while keeping one ear free.
Buying Considerations
Noise control is another important distinction. The Ertuly T33 lists active noise cancellation, with a Transparency Mode for switching how much outside sound you hear. That makes it the clearer choice for someone seeking open ear earbuds for study? Not quite: neither model is an open-ear design. Both are in-ear earbuds, and the T33 is the one that explicitly offers ANC and Transparency Mode. JOYWISE lists passive noise cancellation, which is a different approach and should not be confused with the T33’s active system.
Calls may influence the choice too. JOYWISE describes clear-call performance and uses button controls, while Ertuly lists ENC microphones intended to filter background noise and touch controls for managing audio. The supplied information does not give a comparable call-quality test, so I wouldn’t treat either description as proof of how a conversation will sound in every setting. If you’re searching for crystal clear calls in ear earbuds for study, compare the listed call features with your own priorities: simple button operation on JOYWISE or the T33’s ENC microphone specification.
Finally, match the design to your routine. JOYWISE’s hooks point toward active use, while the T33’s sleep mode and low-profile shape point toward rest. Neither product is described as a dedicated headband-style sleep headphone, and the “sweatproof sleep headphones for study” phrase can blur two different needs. For studying, decide whether you want a stable sports fit or noise-control and sleep-oriented features. If price matters to your decision, check the current price on Amazon using the page’s button rather than relying on an outdated figure.
In my opinion, I’d buy the Ertuly T33 for study because its active noise cancellation and Transparency Mode give it the more useful feature set for a focused listening session. Its sleep mode and compact design also make it the more versatile choice for rest and travel.
I’d choose the JOYWISE 5.3 instead for workouts, a higher listed water-protection rating, or longer playback from one charge. For study specifically, though, the T33’s noise-control options are the deciding factor for me.
The Ertuly T33 is the stronger fit if you want active noise cancellation and a Transparency Mode. JOYWISE may suit you better if a secure sports-style fit and up to 16 hours of continuous playback matter more.
Its stated total is up to 48 hours with the charging case. The earbuds themselves are listed for up to 8 hours per charge, so the total figure includes additional charges from the case.
JOYWISE lists an IPX7 rating, while Ertuly lists IPX6. Those ratings make JOYWISE the higher-rated option on paper, but the T33 is still described as sweat-resistant.
No. Both are listed as in-ear earbuds. The T33 adds active noise cancellation and Transparency Mode, while JOYWISE uses a sports-oriented in-ear design with adjustable hooks.
