If you want a lightweight on-ear headset for everyday Bluetooth listening and long battery life, choose JBL Tune 510; if you need to connect your own wireless earbuds or headphones to a wired audio source, choose Sudio Flyg. For small ears, the key distinction is that the JBL is a complete on-ear headphone, while the Flyg is an adapter; it does not include earbuds.
• JBL Tune 510’s biggest strength: Up to 40 hours of battery life, plus a foldable, lightweight design. Trade-off: It has no noise control and is an on-ear headphone, not a small in-ear earbud.
• Sudio Flyg’s biggest strength: It adds Bluetooth to compatible 3.5 mm audio sources, including in-flight entertainment systems. Trade-off: It is an adapter, so you need to supply your own Bluetooth headphones or earbuds.
• Choose JBL Tune 510 if you want one self-contained headset for wireless listening from a phone and value long battery life.
• Choose Sudio Flyg if the audio source has a headphone jack but lacks Bluetooth, and you already own wireless headphones or earbuds.
The JBL Tune 510 is the more direct choice if you want headphones you can pair with a phone and use for music or other audio without adding a separate adapter. Bluetooth 5 handles the wireless connection, and the listed range is 10 meters. Multi-point connection lets you switch between two Bluetooth devices, which can be useful when you move between a phone and another compatible device during the day.
Battery life is a clear practical advantage: JBL lists up to 40 hours, with a five-minute charge providing up to two additional hours of listening. A full charge takes two hours. The headphones weigh 159 g and fold for carrying, while padded ear cushions are intended to make extended wear more comfortable. The 32 mm dynamic drivers and JBL Pure Bass tuning point toward a bass-forward listening character, rather than a neutral or adjustable sound profile.
For small ears, remember that these are on-ear headphones, not earbuds that sit inside the ear. Their fit depends on the ear cushions resting on the ears; the sheet does not provide ear-cup dimensions or a fit range, so it cannot guarantee comfort for a particular head or ear shape. The product information lists no noise control, so don’t choose it expecting active noise cancellation or a stated sound-isolating feature. It may suit someone looking for an anc kids headset for small ears only if an on-ear fit is acceptable; the specifications do not establish that it is made for children or sized specifically for small ears.

Who should skip it: Skip the JBL if you specifically need in-ear earbuds, noise control, or a way to add Bluetooth to a wired entertainment system.
Sudio Flyg serves a different purpose. It is a Bluetooth transmitter that plugs into a source with a 3.5 mm headphone jack or a dual 3.5 mm flight-audio socket, then sends the audio wirelessly to compatible Bluetooth headphones, earbuds, or earphones. That makes it useful when the device you want to listen to has a wired output but no Bluetooth of its own. Examples listed include airplane entertainment systems, computers, TVs, portable DVD players, gaming devices, and some exercise equipment.
The adapter weighs 24 g and measures 38 × 58 × 15 mm, so it is a small add-on rather than a headset to wear over the ears. Its listed battery life is up to 12 hours, and it can be used while charging if you forgot to charge before a trip. Bluetooth 5.3 is listed in the key features, with a stated reach of 10 meters. The product details also refer to Bluetooth 5.0, so the safest practical takeaway is to focus on its stated wireless-transmitter role and 10-meter reach rather than assuming every listing field describes the same version.
Flyg does not come with earbuds or headphones. For small ears, that can be an advantage if you already have a comfortable pair of small-fit Bluetooth earbuds: the adapter does not dictate what you wear. But it cannot make an uncomfortable earbud fit better, and it does not provide a headset by itself. Its audio input is analog through the supported jack types, so it is not a general solution for a source that has no compatible audio output.
Who should skip it: Skip the Flyg if you want a complete pair of headphones, need an adapter for a source without a 3.5 mm output, or want a headset designed specifically for gaming.
• Best for long battery life in a self-contained headset → JBL Tune 510. Its listed maximum is up to 40 hours, compared with up to 12 hours for the Flyg adapter.
• Best for wired airplane entertainment → Sudio Flyg. It supports a standard 3.5 mm jack and a dual 3.5 mm flight-audio socket, then transmits audio to your own Bluetooth headphones.
• Best if you already own comfortable wireless earbuds for small ears → Sudio Flyg. Keep using the earbuds that fit you; Flyg supplies the wireless connection from a compatible wired source.
• Best for everyday phone listening without extra equipment → JBL Tune 510. The headphones pair directly over Bluetooth, so there is no separate transmitter to connect and charge.
• Best for switching between two Bluetooth sources → JBL Tune 510. Its multi-point feature is specifically listed for moving between Bluetooth devices.
• Best for a compact travel adapter → Sudio Flyg. At 24 g, it adds wireless transmission without replacing your headphones.
• Best if you want a foldable over-ear-placed headset with padded cushions → JBL Tune 510. Its on-ear construction and folding design may suit carrying between home, work, or travel.
• Best gaming headset for small ears → neither is a complete match on the provided specifications. Flyg can transmit audio from some gaming devices to headphones you supply, but the data does not establish gaming latency or microphone support. JBL is a complete headphone, but no gaming-specific features are listed.
Neither product is a conventional open-ear earbud, and the sheets do not provide evidence of an open-ear design or a measured low-latency mode. So if your search is for the best low latency open ear earbuds for small ears, neither product can be confirmed as that based on the available specifications. Flyg’s description uses “lag-free” wording, but it does not provide a latency measurement or establish an open-ear earbud design.
Start with the audio source, not the brand name. If you mainly listen from a Bluetooth phone, the JBL is the straightforward option: it is a complete pair of headphones with its own controls and battery. If you mainly need to make an older or wired source work with Bluetooth headphones, Flyg addresses that specific connection problem. The two products are not interchangeable: one plays audio directly through its own headphones, while the other relays audio to a separate pair.
Next, consider what “for small ears” means in your case. If you need earbuds that sit inside the ear, the JBL’s on-ear design is not a match. Flyg gives you the freedom to select your own earbuds, but it does not include them or provide fit guidance. If you are comparing comfort, check the fit details of the headphones or earbuds you plan to wear; neither sheet gives enough information to promise a particular fit for small ears.
Battery needs are different, too. JBL’s up-to-40-hour figure applies to its headphones, while Flyg’s up-to-12-hour figure applies to the transmitter alone. With Flyg, your own earbuds or headphones also need to be charged. The product information does not state their battery life, so the adapter’s runtime should not be treated as the total runtime of a complete listening setup.
Finally, consider the features you actually need. JBL lists no noise control, and Flyg is not a noise-cancelling device; it simply transmits audio. If you need a microphone, gaming latency details, or an earbud fit designed for children, those points are not established in these product details. For a cost comparison, check the current price on Amazon; the decision here should hinge on whether you need a complete headphone or a Bluetooth adapter.
I would choose the JBL Tune 510 if I wanted one practical wireless headset with long listed battery life and no separate adapter to manage. For small ears, though, I would not assume its on-ear cushions will fit comfortably; I’d choose it only if that style suits me. If I already owned well-fitting earbuds and needed Bluetooth from an airplane jack or another wired source, I’d pick the Sudio Flyg instead.
They are on-ear headphones, not earbuds. The supplied details do not give ear-cushion dimensions or confirm a fit for small ears, so fit depends on whether the on-ear style works for you.
No. Flyg is a Bluetooth transmitter that connects to compatible wired audio outputs and sends sound to Bluetooth headphones or earbuds you provide.
The JBL headphones are listed for up to 40 hours of use. Flyg’s battery life is listed as up to 12 hours, but that figure is for the adapter, not the Bluetooth headphones paired with it.
It is listed as compatible with some gaming devices and controllers that have a suitable audio connection. The product details do not provide a measured latency figure, microphone support, or a gaming-specific performance guarantee.
