If you want app-tailored audio enhancement for teens, choose MEE audio EarBoost EB1; if you need to share airplane audio with a travel partner, choose Avantree Relay. The EB1 is the more direct choice for personal listening, while Relay is a Bluetooth transmitter for a wired audio source—not a pair of earphones.
For teens who want help bringing out detail in music and media, that distinction matters: one shapes listening through an app, the other sends audio to headphones.
That makes this a comparison of two very different tools. The EB1 is an in-ear listening device with an app for tailoring sound; Relay connects a 3.5 mm audio source to Bluetooth headphones and can send the same audio to two pairs. For a teen choosing everyday earphones, the EB1 is the more relevant starting point.
MEE audio EarBoost EB1 vs Avantree Relay at a Glance
• MEE audio EarBoost EB1 strength: App-based sound tailoring intended to follow a listener’s hearing curve. Trade-off: It is a personal pair of earphones, not a way to share one source with another listener.
• Avantree Relay strength: Sends audio from a 3.5 mm source to two Bluetooth headphones or earbuds at once. Trade-off: It is a transmitter only, with no microphone and no phone-call function.
• EB1 fit: Three eartip sizes and flexible earfins offer options for securing the in-ear fit. Its stated Bluetooth range is 10 meters.
• Relay fit: A 25-hour playtime claim, onboard volume controls, and a battery indicator suit long travel sessions. It also includes a dual-prong airplane adapter.
• Choose the EB1 for personal music and media listening; choose Relay for sending wired-source audio to one or two Bluetooth listeners.
The EarBoost EB1’s defining feature is its companion app for iOS and Android. The app is intended to tailor sound to a user’s hearing curve, with the goal of restoring missing detail and improving clarity in music and media. That makes the EB1 more than a straightforward wireless earphone choice: its main appeal is the ability to personalize how audio comes through.
The in-ear design includes three sizes of eartips and flexible earfins. Those fit options are useful for someone who wants to adjust how the earphones sit, rather than being limited to a single tip shape. The package also includes a protective carrying case, and the earphones connect over Bluetooth with a stated range of 10 meters. The stated battery charge time is two hours.
For teens who primarily want a personal pair for music, video, and other media, the EB1 is the clearer match. Its app-based sound adjustment gives it a specific purpose, and the included fit options may help make everyday listening more comfortable. It could also be a candidate when someone is searching for the best with microphone earphones for teens, but the available product details do not specify a microphone. I would not buy it on the assumption that it supports calls.

Who should skip it: Skip the EB1 if the main goal is sharing an airplane screen’s audio with another person, or if a microphone for calls is essential.
Relay is not a set of headphones. It is a compact Bluetooth audio transmitter that takes sound from a 3.5 mm source and sends it to Bluetooth headphones or earbuds. Its dual-link feature allows two pairs to listen to one source at the same time, which is the standout reason to consider it. For a flight, that means two travelers can use their own compatible Bluetooth listening devices with one airplane entertainment system.
The setup is designed around a wired connection: plug Relay into the audio jack, put the headphones into pairing mode, and connect. A dual-prong airplane adapter is included for airplane entertainment systems with that connection. Relay also has volume controls and a battery indicator. The product information lists a 25-hour playtime claim and a two-hour charging time, making battery endurance a notable part of its travel-focused design.
Its limits are important. Relay has no microphone and is not intended for phone calls. It sends audio from a 3.5 mm input; it does not receive audio, replace headphones, or serve as a general-purpose phone or TV accessory. Its supported use is best understood as a bridge between a wired audio output and Bluetooth headphones. That makes it useful for a travel pair, but not a substitute for the EB1 as everyday earphones.
Who should skip it: Skip Relay if you need a standalone pair of earphones, a microphone for calls, or a device that receives Bluetooth audio from a phone.
• Best for personal listening → MEE audio EarBoost EB1. It is the actual pair of in-ear earphones here, with an app for tailoring sound to a listener’s hearing curve.
• Best for sharing one airplane audio source → Avantree Relay. Its dual-link function is designed to connect two pairs of Bluetooth headphones or earbuds to one 3.5 mm source.
• Best for app-based sound adjustment → MEE audio EarBoost EB1. The iOS/Android companion app is intended to customize audio and bring out detail.
• Best for a long trip without frequent charging → Avantree Relay. Its stated playtime is up to 25 hours, with a battery indicator and a two-hour charge time.
• Best for adjustable in-ear fit options → MEE audio EarBoost EB1. It includes three eartip sizes and flexible earfins.
• Best for connecting Bluetooth headphones to a wired airplane jack → Avantree Relay. The dual-prong adapter is included for airplane use.
• Best for phone calls → Neither is a safe pick based on the listed details. Relay explicitly has no microphone, while a microphone is not specified for the EB1.
• Best sweat resistant headphone for teens → Neither can be confirmed from the listed features. Neither product’s details specify sweat resistance, so I would not assume either is suitable for that requirement.
First, be clear about what you are buying. The EB1 is an in-ear Bluetooth listening device. Relay is a transmitter that needs a 3.5 mm audio source and separate Bluetooth headphones or earbuds. If the teen already has headphones and the problem is using them with an airplane entertainment system, Relay may solve that specific connection problem. If the goal is to buy earphones for personal listening, it does not.
Next, consider whether sound tailoring or shared listening matters more. The EB1’s app is meant to adjust sound for a listener’s hearing curve; that is its most distinctive feature. Relay’s standout feature is dual-link audio sharing. These are different benefits, so neither product replaces the other simply by having Bluetooth.
Fit and call needs deserve a separate check. The EB1 includes three eartip sizes and flexible earfins, but that does not establish a fit for every person. Relay’s product details state that it has no microphone, and the EB1’s supplied details do not confirm one. If calls are a must-have, verify that requirement before deciding. Likewise, neither product is documented as sweat resistant, so shoppers looking for a gym-ready or sweat-resistant option should not infer that from the product descriptions.
Finally, think about how the device will be used day to day. A teen looking for kids headphones gift for teens may be better served by the EB1 if the gift is meant to be a pair of personal earphones with app-based sound customization. Relay makes more sense when the gift is specifically for travel and the recipient already owns compatible Bluetooth headphones. Check the current price on Amazon before making a purchase, but make the decision on function first: earphones for one listener or a transmitter for one or two listeners.
In my opinion, I would choose the MEE audio EarBoost EB1 for a teen who wants personal earphones for music and media. Its app-based sound tailoring and included fit options give it a clear everyday listening role. I would pick Relay only for the more specific need to send airplane audio to Bluetooth headphones, especially for two listeners. For teens buying their own earphones, the EB1 is the more sensible choice.
For personal music and media listening, the EB1 is the relevant product because it is a pair of in-ear earphones with app-based sound adjustment. Relay is a transmitter, so it requires separate Bluetooth headphones.
Yes. Relay is designed to send audio from a 3.5 mm source to two pairs of Bluetooth headphones or earbuds at the same time. A dual-prong airplane adapter is included.
Relay does not have a microphone and is not intended for phone calls. A microphone is not specified in the EB1’s listed details, so confirm that feature before choosing it for calls.
The listed product details do not specify sweat resistance for either device. If sweat resistance is essential, do not assume either one has it based on the information provided.
