• LexonElec ATTACK SHARK G300 — biggest strength: a full over-ear headphone with active noise cancellation, a built-in mic, 20-hour battery life and a 3.5mm wired fallback, all in a 210g foldable body.
• LexonElec ATTACK SHARK G300 — biggest trade-off: it's a single listening device, so it can't split one phone's audio between two people, and the 3.5mm cable doesn't carry mic audio.
• Kelvix Type C — biggest strength: a multi-port Type C to 3.5mm adapter with a built-in DAC running at 24-bit/96kHz, letting you connect several headphones or sound devices to one Type C port.
• Kelvix Type C — biggest trade-off: it makes no sound on its own — no drivers, no battery, no mic of its own — so it only matters if you already own wired headphones.
• Who the G300 is for: college students who want one pair of headphones that handles lectures, commuting, calls and late-night study.
• Who the Kelvix adapter is for: anyone who already has wired 3.5mm headphones and needs to plug them into a Type C phone — or share that audio with a friend.
This is a real pair of headphones, not an accessory. The G300 is an over-ear, closed-back design built around 40mm-class dynamic drivers with a 32-ohm impedance and a 20Hz–20KHz frequency range — a standard, easy-to-drive spec that phones and laptops handle without a separate amp. The memory foam earcups and PU leather covering are there for long sessions, and the adjustable headband is meant to fit a range of head sizes. That combination matters for a student who wears headphones through a three-hour study block, a lecture recording and a commute in the same afternoon.
Who should buy it: if you want one device that covers music, calls and noise blocking, and you like the idea of a purple minimalist look, this is the straightforward pick. Who should skip it: if you already own wired headphones you love and just need them to work with a Type C phone, the G300 solves a problem you don't have. Also note two honest limits — there's no RGB lighting, and the bundled 3.5mm cable doesn't pass mic audio, so wired calls aren't an option.
Kelvix Type C: Who It's For
The Kelvix Type C is a different category of product entirely. It's a short adapter cable — about 32cm, weighing just 36g — that turns a single USB Type C port into multiple 3.5mm outputs. Inside is a digital-to-analog converter rated at 24-bit/96kHz, with brass cores and connectors, and it's plug-and-play: no drivers, no setup, no battery. There's also an integrated line-control button for playback and call control.
The "one to four" port layout is the whole point. The manufacturer positions it for content creators, commuters with noise-cancelling headphones, gamers who want audio streamed to more than one device, and remote workers taking online meetings. In practice, the clearest everyday use is sharing: two people, one Type C phone, two sets of wired earbuds, same audio. That's genuinely useful when a friend wants to hear the same thing you're listening to, or when you're recording and need to monitor on one pair while feeding another.
Side-by-Side: Which Should You Choose?
• Best for a complete listening setup → LexonElec ATTACK SHARK G300. It's a finished product: drivers, noise cancellation, mic, battery and a wired option.
• Best for sharing one phone's audio → Kelvix Type C. Multiple 3.5mm outputs on one Type C port is something the G300 simply cannot do.
• Best for long study or commute sessions → LexonElec ATTACK SHARK G300. The memory foam over-ear pads, adjustable headband and 20-hour battery are built for extended wear.
• Best for students who already own wired headphones → Kelvix Type C. It extends gear you have rather than replacing it.
• Best for calls and online meetings → LexonElec ATTACK SHARK G300. The built-in mic is part of the headset; the Kelvix adapter relies on whatever mic your connected device provides.
• Best for travel light → Kelvix Type C. At 36g and 32cm, it disappears into a pocket; the G300 is 210g and folds flat instead.
• Best for audio quality headroom → Kelvix Type C. Its 24-bit/96kHz DAC is a higher-resolution conversion spec than a typical phone's built-in output — though it only matters with good wired headphones.
• Best for one purchase that does everything → LexonElec ATTACK SHARK G300. If you want to buy once and be done, this is the simpler answer.
For most college students, I'd buy the LexonElec ATTACK SHARK G300. It's the only one of the two that actually plays sound, and its combination of over-ear comfort, active noise cancellation, a built-in mic and around 20 hours of battery covers the full day — lectures, library, commute and calls — without extra gear. I'd only pick the Kelvix Type C if you already own wired 3.5mm headphones and specifically need them working on a Type C phone, or you regularly share audio with a second listener. If that's not your situation, the adapter is a solution to a problem you don't have. Before deciding, check the current price on Amazon for both, since value here depends entirely on what you already own.
FAQ
That's exactly what it's designed for. The multi-port layout lets you connect several 3.5mm devices to a single Type C port for shared listening and clear calls, and it's plug-and-play with a built-in 24-bit/96kHz DAC. You'll need wired headphones to use it.
Only in one direction, and awkwardly. The G300 can run wired through its 3.5mm cable, so the Kelvix adapter could feed it audio from a Type C phone — but remember the G300's audio cable doesn't carry mic audio, so calls over that wired path won't work.
It depends on what you own. If you need a headset, the G300 delivers far more function per purchase. If you already have wired headphones and just need a Type C bridge or an audio splitter, the Kelvix adapter is the cheaper way to solve that specific problem. Check the current price on Amazon for both before you decide.
