If you want a compact way to send audio from a 3.5mm jack to Bluetooth headphones for cycling, choose MEE audio Connect Air in-Flight; if you need children’s passive hearing protection for loud settings, choose PROTEAR Kids Hearing Protection. They solve different problems: one transmits audio, while the other reduces exposure to surrounding noise. Neither is a cycling headphone designed to play music on its own.
• MEE audio Connect Air in-Flight: Its main strength is sending audio from a 3.5mm jack to as many as two Bluetooth headphones. Its trade-off is that it is a transmitter, not a headset or hearing protector.
• PROTEAR Kids Hearing Protection: Its main strength is adjustable, foldable earmuffs rated at 25 dB NRR. Its trade-off is that it reduces outside sound rather than playing wireless audio.
• Choose MEE if you have a compatible audio source and Bluetooth headphones; choose PROTEAR if a child needs earmuffs for noisy activities.
• For cycling: MEE is the closer match only if you already have a suitable 3.5mm audio source and Bluetooth headphones. PROTEAR is for noise reduction, not listening to a cycling soundtrack.
MEE audio Connect Air in-Flight is a small Bluetooth transmitter that takes audio from a standard 3.5mm AUX jack and sends it wirelessly to headphones or speakers. Its intended airplane use is straightforward: plug it into an in-flight entertainment jack and pair it with Bluetooth headphones. The included two-prong adapters address airplane systems that use that connector. It can also send audio to two Bluetooth devices at once, which is useful when two people want to listen to the same source.
The 3.5mm input gives it uses beyond flights. The listed compatible sources include computers, game controllers, televisions, treadmills and other gym equipment. For cycling, it could form part of an audio setup if the rider has a compatible 3.5mm source, Bluetooth headphones and a safe way to carry and use them. But it is not a standalone headset: there is no built-in headphone, microphone or cycling-specific feature in the listed specifications. Someone searching for the best with mic wireless headset for cycling should not treat this transmitter as a complete solution.
Battery life is listed as up to 20 hours with one pair of headphones connected and up to 15 hours with two. It can also be used while charging. The stated charge time is two hours, and charging uses USB-C. aptX Low Latency is intended to reduce the delay between picture and sound, though that benefit depends on using compatible headphones. Its compact dimensions—1.5 by 0.6 by 1.8 inches—make it a small accessory rather than another full-size headset to manage.
Who should skip it: Skip MEE if you need hearing protection, a microphone, or headphones that work without a separate audio source and Bluetooth headset.
PROTEAR Kids Hearing Protection is an over-the-head pair of earmuffs for children, with an adjustable headband and 360-degree swivel ear cups. The product is listed for ages 3–16, while its feature description also refers to a fit range of 3–15. The adjustable design is intended to accommodate different head sizes, and the swiveling cups can help the earmuffs sit more naturally around a child’s ears. These are passive noise-reducing earmuffs, not Bluetooth headphones.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

The earmuffs fold by tucking the ear cups back into the headband, making them easier to put away in a backpack than an unfolded over-ear shape. The listed dimensions are 3 by 4 by 4 inches, and the style is pink with a cartoon pattern. Those details may matter for storage and a child’s preferences, but they do not change the basic function: reducing surrounding noise. There is no listed audio input, wireless connection or microphone.
Who should skip it: Skip PROTEAR if you want music playback, a microphone, or a headset for cycling communication; its purpose is hearing protection, not audio.
• Best for transmitting audio from a 3.5mm jack → MEE audio Connect Air in-Flight. It converts a wired audio output to Bluetooth for compatible headphones or speakers.
• Best for a child at a loud event → PROTEAR Kids Hearing Protection. Its 25 dB NRR rating and over-ear design are aimed at reducing surrounding noise.
• Best for two listeners sharing one source → MEE. It can transmit to up to two Bluetooth headphones or speakers at the same time.
• Best for foldable storage in a child’s bag → PROTEAR. Its ear cups fold back into the headband.
• Best for long audio sessions without a nearby outlet → MEE. The stated battery life is up to 20 hours with one connected pair, or up to 15 hours with two.
• Best for a child who needs adjustable earmuffs → PROTEAR. Its headband adjusts, and its ear cups swivel.
• Best for cycling with audio equipment already in place → MEE, with important limits. It supplies a wireless audio link from a 3.5mm source, but it is not itself a headset, a microphone or a waterproof cycling product.
• Best IPX7 waterproof headphones for cycling → neither. Neither data sheet lists an IPX7 rating or describes either product as waterproof.
Start with the job you need the product to do. If you want audio to reach Bluetooth headphones from a device with a 3.5mm output, MEE is the relevant choice. It does not replace those headphones; it connects the source to them. Check that your audio device actually has a compatible jack and that your headphones can pair with the transmitter. If you want two people to listen, the two-device feature may be useful, but the listed battery life is shorter with two connected headphones than with one.
For cycling, be especially clear about what “headset for cycling” means to you. MEE can be one piece of an audio chain, but the supplied information does not describe a microphone, a helmet attachment, a waterproof rating or any cycling safety feature. It therefore cannot be called the best with mic wireless headset for cycling. Nor does it meet a search for the best IPX7 waterproof headphones for cycling: no IPX7 claim is provided. A transmitter’s ability to connect wirelessly does not establish that the whole setup is suitable for riding.
Finally, think about what you will carry and store. MEE is a small transmitter with a built-in rechargeable battery, USB-C charging and supplied airplane adapters. PROTEAR is a child-sized, foldable over-ear accessory with an adjustable headband. They are not substitutes for each other, and the right decision follows from whether you need a wireless audio connection or passive hearing protection.

My Verdict
I would choose MEE audio Connect Air in-Flight if I wanted to send audio from a 3.5mm source to Bluetooth headphones, including as one part of a cycling setup.
It has a clearly defined job, useful multi-device transmission and up to 20 hours of listed battery life with one pair connected.
For a child who needs noise-reducing earmuffs, I would choose PROTEAR instead; its adjustable, foldable design serves a different need.
Neither is a complete cycling headset, and neither is described as waterproof.
It is a Bluetooth audio transmitter, not a headset. It sends audio from a 3.5mm source to compatible headphones, but the listed features do not include a microphone, waterproofing or cycling-specific design.
No audio playback or Bluetooth connection is listed. They are over-the-head earmuffs designed to reduce surrounding noise, with a stated 25 dB NRR rating.
They address different needs on a flight. MEE can send audio from an airplane entertainment jack to Bluetooth headphones; PROTEAR is designed to reduce noise around a child. Choose based on whether audio connection or hearing protection matters more.
Neither product is listed with an IPX7 rating. The supplied information does not describe either as waterproof, so neither can be recommended on that basis.
