If you want open-ear comfort and long battery life for sports workout, choose JOYROOM Open Ear Headphones; if you need compact, discreet earbuds for small ear canals, choose Lintorea Mini Invisible Earbuds.
JOYROOM’s open-ear hook design keeps your ear canals uncovered, while its case is specified for up to 50 hours of total playback. Lintorea takes the opposite approach: tiny in-ear buds built around a low-profile fit, with up to 24 hours combined playback from the case. The key decision is whether you want an open fit or a tucked-away earbud.
• JOYROOM’s strength: open-ear hook design, 12.5 hours of playback per charge, and up to 50 hours with the case. Trade-off: its open fit does not provide active noise cancelling.
• Lintorea’s strength: a compact in-ear shape intended for small ear canals and discreet everyday listening. Trade-off: its 4–5 hours per charge and up to 24 hours with the case mean more frequent charging.
• For sports workout: JOYROOM is the more fitting choice on paper, with an open-ear design and IPX4 resistance to sweat and rain.
• For small ears or a low-profile look: Lintorea is the more targeted option, with soft silicone and an IPX5 rating for sweat and rain.
• Choose JOYROOM if you want longer playback and to remain more aware of surrounding sound; choose Lintorea if compact in-ear placement matters more than long battery life.
JOYROOM’s defining feature is its open-ear hook design. Each earbud weighs 10 grams, and the non-invasive fit leaves the ear canal uncovered. That makes it a reasonable option for someone who dislikes having an earbud seated inside the canal or wants to hear more of the surrounding environment while listening. The product is not presented as noise-cancelling, and that is an important part of the trade-off: it is designed to let outside sound remain present, not block it out.

Battery life is the strongest practical advantage in this comparison. JOYROOM lists 12.5 hours from one charge and up to 50 hours with the charging case. A digital display shows battery information, and Bluetooth 5.4 handles the wireless connection. For workouts, the IPX4 rating is specified for resistance to sweat and rain. Touch controls are provided for tasks such as adjusting volume, skipping tracks, and taking calls.
I’d consider JOYROOM if you want open-ear headphones for big ears, prefer not to fill your ear canals, or need extended listening between charges. I’d skip it if your priority is a discreet, nearly invisible in-ear fit, or if you want to reduce outside sound: an open design is not a substitute for active noise cancelling. Its hooks may also be more noticeable than Lintorea’s compact buds, so the choice comes down to wearing style as much as battery life.
Lintorea is built around a small, rounded in-ear shape intended for users who find regular earbuds too bulky. Its soft silicone fit and low-profile design aim to sit discreetly in the ear for work, commuting, study, and everyday listening. The product also includes small and large earcaps, giving buyers two included sizes to try. The listed sleep-wearing guidance suggests adjusting the earbuds’ position to reduce accidental pillow contact, but the key appeal remains their compact form.
The battery trade-off is clear. Lintorea specifies about 4–5 hours of playback per charge and up to 24 hours total with the case. The slide-style case has a battery percentage display, and the earbuds use Bluetooth 5.4 with touch controls and automatic reconnection after initial pairing. Their IPX5 rating is specified for sweat and rain resistance. That protection level is higher than JOYROOM’s listed IPX4, but it does not change the difference in fit: Lintorea sits in the ear canal, while JOYROOM does not.
I’d look at Lintorea if you have small ear canals, want earbuds that are less conspicuous, or prefer an in-ear design for commuting and desk use. I would not choose it for long stretches away from the case if minimizing charging breaks is a priority. Nor is it the obvious pick for someone who wants an open fit that leaves the ear canal uncovered.
• Best for sports workout with an open fit → JOYROOM Open Ear Headphones. Its hook-style placement leaves the ear canal open, and IPX4 is specified for sweat and rain resistance.
• Best for small ear canals → Lintorea Mini Invisible Earbuds. Its compact design is specifically aimed at people who find standard earbuds uncomfortable or bulky.
• Best for longer listening between charges → JOYROOM. It lists 12.5 hours per charge and up to 50 hours with the case, compared with Lintorea’s 4–5 hours and up to 24 hours.
• Best for a discreet appearance → Lintorea. Its low-profile in-ear placement is designed to be less noticeable than an open-ear hook.
• Best for staying more aware of nearby sound → JOYROOM. The open-ear design does not seal the ear canal, though it also does not provide active noise cancelling.
• Best for sweat and rain resistance by listed rating → Lintorea. Its IPX5 rating is above JOYROOM’s IPX4; neither rating should be treated as permission to submerge the earbuds.
• Best if you want a battery display → Either. Both products specify a display on the charging case, though Lintorea describes a percentage display and JOYROOM describes an LED battery display.
• Best for children looking for true wireless earbuds → Check fit and intended use carefully. Both products are described for adults, so neither should be treated as specifically designed for children. A volume limiting bluetooth earbuds bluetooth 5.3 feature is not listed for either model; both use Bluetooth 5.4, and neither sheet specifies volume limiting.
My Verdict
JOYROOM is the more natural match if you want an open-ear design, with IPX4 resistance to sweat and rain. Lintorea has an IPX5 rating for sweat and rain, but its compact in-ear fit is aimed more at small-ear comfort and discreet everyday listening.
Neither product’s listed features support a claim of active noise cancelling. JOYROOM explicitly uses an open-ear design and is intended to keep the listener connected to surrounding sound; Lintorea lists no noise control.
JOYROOM lists 12.5 hours per charge, compared with Lintorea’s approximately 4–5 hours. With the cases, the stated totals are up to 50 hours for JOYROOM and up to 24 hours for Lintorea.
Neither product is described as having volume limiting, and both are listed for adults. Both use Bluetooth 5.4; the available details do not establish either as a child-specific or hearing-protection product.
