If you want a simple Bluetooth transmitter that can connect two headphones and includes an airplane adapter, choose LENDAWAY 5.4; if you need stated long-play battery life and low-latency support, choose MEE audio Connect Air in-Flight. For elderly travelers, the clearest choice depends on whether straightforward dual-headphone use or more specific battery and audio features matter most.
LENDAWAY 5.4 vs MEE audio Connect Air in-Flight at a Glance
• MEE audio Connect Air in-Flight: Its main strength is clearly stated battery life—up to 20 hours with one pair of headphones, or 15 hours with two—plus aptX Low Latency support for compatible headphones. Its trade-off is that its battery life is shorter when two pairs are connected, and low-latency benefits require aptX-compatible gear.
• Choose LENDAWAY if: you want a Bluetooth 5.4 transmitter with a dual-headphone connection and a dual 3.5mm airplane adapter.
• Choose MEE audio if: you want specified battery estimates, USB-C charging, and low-latency support for compatible equipment.
LENDAWAY 5.4 is a Bluetooth audio transmitter and receiver with a 3.5mm AUX audio input and stereo output. In transmitter use, it can connect a wired audio source—such as an in-flight entertainment system, television, laptop, or gym machine—to Bluetooth headphones. Its listed compatible devices also include smartphones, tablets, gaming devices, car stereos, home stereo systems, and portable DVD players. That range makes it relevant beyond flights: it can suit someone who wants to make several kinds of 3.5mm audio sources work with wireless headphones.
The feature I would focus on for an older traveler is its dual-link capability. LENDAWAY says it can pair two wireless headphones simultaneously, so two people can listen to the same source without sharing one set of earbuds. It also includes a dual 3.5mm airplane headphone adapter, which is useful when the aircraft seat’s audio connection has two prongs. Bluetooth 5.4 and a built-in microphone are listed as features, and the product supports hands-free calling. The information provided does not specify battery runtime, so I would not choose it on the assumption that it will last a particular number of hours.
Who should skip it: Skip LENDAWAY if a stated battery-life estimate or explicit low-latency support is essential to your decision.

MEE audio Connect Air in-Flight is a Bluetooth transmitter for 3.5mm AUX sources. It is designed to send stereo audio from an airplane entertainment system to up to two AirPods or other Bluetooth headphones or speakers. The listed sources also include computers, gaming systems and controllers, treadmills, A/V receivers, televisions, and portable DVD players. If a listener’s main goal is to use wireless headphones with wired entertainment equipment, that broad set of examples gives a useful picture of where it may fit.
Its strongest documented advantage is the battery estimate: up to 20 hours with one pair of headphones connected and up to 15 hours with two. It can also be used while charging, and the listed charging connection is USB-C, with a two-hour charge time. Those details help a buyer plan around long travel days or use near a charging point. aptX Low Latency is included for compatible headphones, which is intended to reduce audio delay; that benefit should not be assumed for headphones that do not support aptX Low Latency. The product includes two-prong airplane adapters, and its compact listed dimensions are 1.5 by 0.6 by 1.8 inches.
Who should skip it: Skip MEE audio if you need a receiver function as well as a transmitter; its listed purpose is transmitting audio from a 3.5mm source to Bluetooth devices.
This may suit someone who already owns AirPods or other Bluetooth headphones and wants a dedicated way to connect them to an in-flight jack. Its two-headphone option can also work for a travel companion, with the stated trade-off of reduced playtime compared with one connected pair. Like LENDAWAY, it is an audio adapter rather than a headphone set. It cannot, by itself, answer whether particular earbuds will feel comfortable for an older listener or stay secure during exercise.
• Best for a stated single-pair battery estimate → MEE audio Connect Air in-Flight. It specifies up to 20 hours with one pair connected. LENDAWAY’s details do not provide a runtime figure.
• Best for two listeners who want to share one source → Either, with different details to weigh. Both support two Bluetooth headphones; MEE audio specifies up to 15 hours in that setup, while LENDAWAY lists dual link without a runtime estimate.
• Best for Bluetooth 5.4 explicitly listed → LENDAWAY 5.4. That version is part of its stated feature set.
• Best for aptX Low Latency support → MEE audio Connect Air in-Flight. This is useful only when the connected headphones also support the format.
• Best for a product described as both transmitter and receiver → LENDAWAY 5.4. Its product details identify both functions; MEE audio is presented as a transmitter.
• Best for USB-C charging and use while charging → MEE audio Connect Air in-Flight. Both details are specified for this model.
• Best for a dual 3.5mm airplane adapter listed with the device → LENDAWAY 5.4. MEE audio also includes two-prong adapters, so check which adapter arrangement matches the seat jack you expect to use.
• Best for converting a treadmill or other 3.5mm source to Bluetooth audio → Either. Both are described for gym-related use, including gym equipment or treadmills.
For someone comparing the best comfortable open ear headphones for elderly listeners, neither adapter should be mistaken for the headphones themselves. The important next step is to check the fit and controls of the Bluetooth headphones that will connect to it. The transmitter can address the wired audio connection; it does not determine whether earbuds are open-ear, comfortable, or easy to handle.
I would choose MEE audio Connect Air in-Flight for an elderly traveler if a clear battery estimate and the option to use it while charging are the priorities. The specified 20-hour single-pair and 15-hour dual-pair figures make trip planning more concrete, while aptX Low Latency is a useful extra for compatible headphones.
I would choose LENDAWAY instead if Bluetooth 5.4, receiver capability, or its stated dual-link setup better matches the devices already at hand. For elderly travelers, I would make the final call based on the headphones’ fit and ease of use as well as the adapter.
Before choosing, check the audio connection on the equipment you plan to use. Both products take audio through a 3.5mm AUX input, so the source needs a compatible jack or an appropriate connection arrangement. The included airplane adapters are relevant to two-prong seat connections; they do not replace the need to confirm that the adapter matches the entertainment system.
Think about how many people will listen. Both products support two Bluetooth headphones, but MEE audio gives different battery estimates for one pair and two. If you often travel with someone and intend to connect both headphones, its stated 15-hour estimate is more useful for planning than an unspecified runtime. If you prefer LENDAWAY’s Bluetooth 5.4 or receiver function, bear in mind that its listed product information does not give a comparable battery figure.
Also consider the headphones themselves. Neither option supplies the comfort, sound isolation, physical controls, or fit of a headphone set; each sends audio to Bluetooth headphones or speakers. For older users, pairing steps and headphone controls may matter as much as the transmitter’s connector. If the intended headphones support aptX Low Latency, MEE audio’s feature may help reduce sound delay. Without compatible headphones, that particular benefit should not guide the decision.
Both are intended to send audio from a 3.5mm airplane entertainment connection to Bluetooth headphones, and both support two headphones. MEE audio provides stated playtime estimates; LENDAWAY lists Bluetooth 5.4, dual link, and a dual 3.5mm airplane adapter.
Yes. Both product details describe a two-headphone connection. MEE audio specifies up to 15 hours of use with two pairs connected; LENDAWAY does not state a battery runtime.
No. aptX Low Latency is listed, but the connected headphones also need to support aptX Low Latency to use that feature. The product’s listed compatibility with Bluetooth headphones does not mean every model supports the same audio format.
That depends on the audio source and the headphones the traveler will use. MEE audio gives a clear battery estimate and can be used while charging; LENDAWAY adds a receiver function and lists Bluetooth 5.4. Neither product is itself a pair of comfortable headphones, so fit and ease of use depend on the separate headphones.
