How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a playful, lightweight set of over ear office headphones that a kid or a casual listener can wear for class, travel and video calls, choose E-Greetshopping Kids; if you need serious active noise cancellation, longer battery life and a more grown-up fit for a noisy office, choose ATTACK SHARK G300.
• E-Greetshopping Kids — biggest strength: colorful LED lights on both earcups plus a foldable, easy-to-carry plastic build that suits kids, students and light everyday listening.
• E-Greetshopping Kids — biggest trade-off: it relies on passive sound isolation rather than active noise cancellation, and its frequency range tops out at 200 Hz, so it is not built for critical listening.
• ATTACK SHARK G300 — biggest strength: active noise cancellation that reduces ambient noise, dual 40 mm drivers and a 20 Hz–20 kHz frequency range for full-range sound.
• ATTACK SHARK G300 — biggest trade-off: the battery spec is listed at 20 hours, and the leather-and-plastic build is heavier in feel than a foldable kids set.
• Pick E-Greetshopping Kids if you want a fun, foldable, kid-friendly wireless headset for classroom, tablet, airplane and travel use.
• Pick ATTACK SHARK G300 if you want a focused work companion that quiets office chatter and airplane rumble while you work, game or take calls.
The E-Greetshopping Kids headset is built around fun and convenience rather than audiophile ambition. The headline feature is the colorful LED lighting on both sides of the headphones, which pulses with the rhythm of the music. That is a design choice aimed squarely at younger listeners and anyone who wants their gear to look lively rather than serious. It is a wireless Bluetooth 5.0 headphone with a built-in mic, so it handles hands-free calling and video-class audio without extra hardware.
On the spec side, this is a 32 ohm, 96 dB dynamic-driver headphone with a frequency range of 20 Hz to 200 Hz. That range is narrow by full-size headphone standards, and it tells you what this set is for: speech, casual music, tablets, airplanes and classroom tasks, not analytical listening. Bluetooth range is listed at 10 meters, which is enough to walk around a room while your device stays put. There is also a 3.5 mm jack and a wired cable in the box, so you can fall back to a wired connection when you want to. The foldable design saves space and makes it easy to toss in a bag.
Who should buy it? Parents shopping for a first proper over ear headphone for a kid, students who want something light and cheerful for online classes, and travelers who want a foldable set that packs small. Who should skip it? Anyone who needs to cancel out a loud office or airplane cabin. This model uses sound isolation, not active noise cancellation, so it muffles rather than erases background noise. If deep bass, full-range music and serious quiet are your priorities, look at the other pick.
The ATTACK SHARK G300 is the more work-oriented of the two. Its centerpiece is active noise cancellation, which the spec sheet says reduces external ambient noise by 95 percent — the kind of figure aimed at airplane engines, subway rumble, office chatter and construction noise. There is a dedicated button for switching modes, so you can toggle between quiet focus and normal listening without digging through menus. For an open-plan office or a commute, that is the single most useful feature here.
Sound is handled by dual 40 mm dynamic drivers with a frequency range of 20 Hz to 20 kHz, which is the full audible band. That means real bass extension and treble detail, not just the mid-focused output of a kids set. The built-in high-definition microphone is positioned for phone calls, video conferences and online classes. Connectivity is Bluetooth 5.3 with a listed range of 33 feet, and there is a 3.5 mm jack plus a cable included, so you can go wired when you want to.
Comfort gets real attention too. The earcups use soft protein leather over highly elastic sponge, and the headband is adjustable with 90-degree inward rotation, so it adapts to different head shapes. The listed battery life is 20 hours. That is a full workday plus change, though it is worth noting that noise cancellation is power-hungry and real-world runtime depends on how you use it. Who should buy it? Remote workers, gamers, students in noisy dorms and frequent flyers who want one headphone to do focus, calls and entertainment. Who should skip it? Anyone who wants a very light, playful, kid-first headset — this one is styled in black with a more serious, adult look.
• Best for quieting a noisy office or flight → ATTACK SHARK G300. Active noise cancellation is the deciding feature here; the E-Greetshopping set only isolates sound passively.
• Best for kids, classrooms and playful style → E-Greetshopping Kids. The LED-lit earcups and white finish are clearly aimed at younger users.
• Best for full-range music and bass → ATTACK SHARK G300. Its 20 Hz–20 kHz range and dual 40 mm drivers beat a 20 Hz–200 Hz range on paper.
• Best for packing and travel bulk → E-Greetshopping Kids. The foldable, space-saving design is its stated strength.
• Best for Bluetooth generation → ATTACK SHARK G300. Bluetooth 5.3 is newer than Bluetooth 5.0, which usually means better efficiency and pairing stability.
• Best for wireless reach around a home or office → ATTACK SHARK G300. A 33-foot range beats a 10-meter range in practice.
• Best for calls and meetings → ATTACK SHARK G300. The HD microphone is explicitly pitched at conferences and online classes, while the E-Greetshopping mic is a general hands-free option.
• Best for a first headphone with wired backup → E-Greetshopping Kids. Both include a 3.5 mm jack and cable, but the lighter, simpler set is easier for a beginner to live with.
If I were buying for myself, I would pick the ATTACK SHARK G300. In my opinion, active noise cancellation, a 20 Hz–20 kHz range, Bluetooth 5.3, a 33-foot range and a 20-hour battery add up to a more capable over ear office headphone for work, calls and travel. I recommend the E-Greetshopping Kids set only if the listener is a child, or if the LED look and foldable design matter more than quiet and sound range. For a shared office or a long flight, the G300 is the one I would reach for. Check the current price on Amazon before deciding, since that is the one number that can swing the call.
Over ear headphones rest around the ears and use dynamic drivers to convert electrical signals into sound. The E-Greetshopping Kids uses a 32 ohm dynamic driver with sound isolation, while the ATTACK SHARK G300 uses dual 40 mm dynamic drivers plus active noise cancellation.
Lifespan depends on build and care, not on a single spec. The ATTACK SHARK G300 lists a 20-hour battery life per charge, while the E-Greetshopping Kids is a Bluetooth 5.0 set with a foldable plastic build and a wired 3.5 mm fallback that keeps it usable even when the battery runs down.
Listening at high volume for long periods is the real risk, regardless of model. Both of these are over ear designs with volume you control, and the ATTACK SHARK G300's noise cancellation actually lets you keep the volume lower in loud places because you are not fighting background noise.
There is no single answer — it depends on your use case. In my opinion, for noisy offices and travel the ATTACK SHARK G300 is the stronger pick thanks to active noise cancellation and a full 20 Hz–20 kHz range, while the E-Greetshopping Kids is the better fit for children and casual, colorful everyday listening.
