If you want simple, lightweight headphones for schoolwork and shared devices, choose ELECDER i37; if you need wireless earbuds with noise cancellation and more audio features for teens, choose Moondrop Space Travel 2. For a head phones gift for teens, the choice comes down to dependable wired simplicity versus a feature-rich Bluetooth setup.
• ELECDER i37: Its foldable on-ear design and 3.5 mm plug make it straightforward to use with compatible devices; the trade-off is that it is wired and has no wireless connection.
• Moondrop Space Travel 2: Its in-ear Bluetooth design includes active noise cancellation, LDAC support, and a game mode; the trade-off is that it needs charging and does not connect through a headphone jack.
• ELECDER i37 is for: Teens who use laptops, tablets, or other devices with a 3.5 mm jack and want a simple pair they can fold into a bag.
• Moondrop Space Travel 2 is for: Teens who prefer wireless earbuds, use Bluetooth, and want features such as dual-device connectivity and noise cancellation.
• These products solve different everyday problems. The i37 is a compact wired headphone for school, travel, and compatible devices. The Space Travel 2 is a wireless in-ear option with more connection and listening features, plus a charging routine. Neither is the automatic choice for every teen. The right pick depends on the devices they use, whether they prefer an on-ear headphone or in-ear earbuds, and how much they value wireless features.
The ELECDER i37 is a lightweight, foldable on-ear headphone with a wired 3.5 mm connection. Its 5.6-ounce weight and folding design make it easy to carry in a school bag or pack for a trip. The L-shaped plug is intended to connect with compatible devices, including laptops, PCs, tablets, smartphones, DVD players, and Kindles. That straightforward compatibility is its main appeal: no Bluetooth pairing and no battery charging are needed.
I would consider the i37 for a teen who mainly listens from a school laptop or tablet with a headphone jack, or who shares devices with different connection habits. It could also suit families looking for a simple set of headphones for car rides and schoolwork. Its listed 20 Hz to 20,000 Hz frequency range and 32-ohm impedance describe basic audio specifications, but they do not establish how one person will perceive sound quality. The supplied facts list sound isolation, but do not give a noise-reduction figure.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Updated: 2026-10-19 · 7 min read · Independent comparison
The Moondrop Space Travel 2 is a wireless, in-ear model built around a 13 mm planar magnetic driver. It supports Bluetooth 6.0 and LDAC, with SBC and AAC also listed as supported codecs. For a teen who wants to avoid a headphone cable, its Bluetooth connection is the central convenience. The stated Bluetooth range is 10 meters in an open environment, and the earbuds can connect to two devices simultaneously, with switching handled through the app.
This model has a broader feature set than the i37. It includes active noise cancellation and an environmental-noise-cancellation system intended to make voices clearer during calls. Its listed game mode has a signal delay as low as 55 milliseconds. The earbuds also support automatic reconnection and switching between using one earpiece and both, including when an earpiece is returned to the charging case. Those functions may appeal to a teen moving between a phone, a computer, and casual gaming.
The trade-offs are just as important. The Space Travel 2 has no headphone jack, so it is not the direct choice for an older wired device or for someone who wants to avoid Bluetooth. Its listed average battery life is seven hours, which means charging belongs in the routine. The provided details include S, M, and L eartips, but the fit still depends on the wearer’s ears and preference for in-ear earbuds. Teens who dislike inserting earbuds, or who want an open-ear design, should look elsewhere. The listed age description is adult and young adult, so families should consider whether an in-ear fit and its wireless controls suit the intended user.
• Best for a wired school laptop or tablet with a 3.5 mm jack: ELECDER i37. It connects directly by cable, without Bluetooth pairing.
• Best for teens who want wireless listening: Moondrop Space Travel 2. It uses Bluetooth 6.0 and has no headphone jack.
• Best for folding into a school bag: ELECDER i37. Its foldable design and 5.6-ounce listed weight support easy packing.
• Best for noise-control features: Moondrop Space Travel 2. It lists active noise cancellation and environmental noise cancellation.
• Best for switching between two paired devices: Moondrop Space Travel 2. It supports simultaneous dual-device connectivity, with device switching through the app.
• Best for a simple, no-charging routine: ELECDER i37. Its wired connection does not require the user to charge the headphones.
• Best for a teen interested in a low-latency game mode: Moondrop Space Travel 2. The listed game-mode delay is as low as 55 milliseconds.
• Best for someone who prefers on-ear headphones over in-ear earbuds: ELECDER i37. Its on-ear design avoids the in-ear fit, though it still rests on the ears.
These choices are about fit and routine as much as feature lists. A teen who regularly forgets to charge devices may find the i37’s cable easier to live with, provided their device has the right jack. Someone who moves between Bluetooth devices and wants noise-control features may get more utility from the Space Travel 2, provided they are comfortable with earbuds and remember to charge them.
The audio specifications also point to different approaches, not a guaranteed winner in sound. The i37 lists a dynamic driver and a 20 Hz to 20,000 Hz frequency range. The Space Travel 2 uses a planar magnetic driver and supports LDAC transmission. Those facts help distinguish the designs, but they cannot settle personal preferences for sound, volume, or fit. I would not choose either one solely from a driver label or codec name.
For shoppers searching for the best extra bass in ear earbuds for teens, the Space Travel 2 is the only in-ear option here, but the supplied information does not state a bass emphasis or a bass tuning target. It would be misleading to promise extra bass based on the driver type alone. The i37 is an on-ear headphone rather than an in-ear model, so it does not match that particular form factor.
My Verdict
The i37 suits teens who want wired on-ear headphones and use a device with a 3.5 mm jack. The Space Travel 2 suits teens who prefer Bluetooth in-ear earbuds and want features such as active noise cancellation and dual-device connectivity.
The i37 connects through a 3.5 mm plug, so a device needs a compatible jack for a direct connection. The product information does not list wireless connectivity or an included adapter.
It lists active noise cancellation and an environmental-noise-cancellation system. Its listed average battery life is seven hours; the supplied details do not give a combined listening duration that includes the charging case.
For schoolwork on a compatible laptop or tablet, the i37 offers a foldable wired design. For travel or gaming where Bluetooth, noise cancellation, and a listed 55-millisecond game mode are priorities, consider the Space Travel 2. Check the current price on Amazon if price is part of your decision; the right fit and device compatibility matter just as much.
