If you want a proven all-rounder for travel and long listening sessions, choose Picun Active Noise Cancelling; if you need a lightweight, gaming-friendly over-ear with a bold look, choose ATTACK SHARK G300.
• Picun Active Noise Cancelling — biggest strength: Hi-Res certified 40mm dynamic drivers, Bluetooth 5.3, and a tested-style 40-hour battery claim with USB-C fast charging that gets you 4 hours from a 10-minute top-up.
• Picun Active Noise Cancelling — biggest trade-off: The spec sheet lists a 2.5-hour full charge time and a "battery average life" field of 4 hours, which sits awkwardly next to the 40-hour headline figure — worth understanding before you buy.
• ATTACK SHARK G300 — biggest strength: Dual 40mm drivers, ANC rated to cut external noise by 95%, and a lightweight protein-leather build with 90° inward-rotating cups that fold flat for storage.
• ATTACK SHARK G300 — biggest trade-off: Its listed battery average life is 20 hours, roughly half the Picun's claimed figure, and it has no advertised fast-charge shortcut.
• Who each pick is for: Picun for flyers, commuters, and office workers who want maximum listening time per charge. ATTACK SHARK G300 for gamers and casual users who want comfort, a distinctive purple finish, and don't need marathon battery life.
The Picun ANC-05L is built around one idea: keep you listening for as long as possible without discomfort. Its 40mm dynamic drivers carry Hi-Res certification and reproduce frequencies from 20 Hz to 20,000 Hz, with 32-ohm impedance and 35 dB sensitivity — numbers that suggest it'll play loud and detailed off a phone without needing a separate amp. Deep bass is clearly a design priority here, which suits pop, hip-hop, and movie soundtracks more than critical acoustic listening.
The ANC system is rated to reduce noise in planes, subways, cars, and crowded spaces by up to 95%, and there's an AI ENC microphone that automatically suppresses background noise during calls. That combination — quiet room, clear voice on the other end — is exactly what remote workers and frequent flyers actually need. The foldable frame, 100° swiveling ear cups, memory foam padding, and 200 g weight all point to a headset you can wear for a full workday or a long-haul flight without your ears screaming at you. It also ships with a 3.5mm aux cable, so you can go wired on a PC or desktop when Bluetooth isn't an option.
Who should skip it? If you want a headset primarily for gaming aesthetics or a specific colorway, this black over-ear is plain by comparison. And if you're the type who forgets to charge, note that the spec sheet's "battery average life" figure of 4 hours is far below the 40-hour headline — the 40-hour claim almost certainly assumes ANC off and moderate volume, so treat it as a best-case number.
The ATTACK SHARK G300 is the more style-forward of the two. It comes in purple with a leather-and-plastic over-ear enclosure, and its design language leans toward gaming and casual media rather than corporate travel. Dual 40mm dynamic drivers deliver the same 20 Hz–20,000 Hz frequency range as the Picun, tuned for what the brand calls deep, powerful, immersive sound — again, bass-first rather than neutral.
Comfort is clearly the second pillar here. The ear muffs use protein leather and highly elastic sponge, the headband is adjustable, and the cups rotate 90° inward so they lie flat in a bag. That flat-fold design is genuinely useful if you toss your headphones into a backpack between classes or gaming sessions. Bluetooth 5.3 gives you the same modern connection standard as the Picun, with a stated range of 33 feet, and there's a 3.5mm jack for wired use plus a built-in HD microphone for calls, video conferences, and online classes.
The real trade-off is endurance. The G300's listed battery average life is 20 hours — half the Picun's claim — and there's no fast-charge feature advertised. For a gamer who plays in two-hour blocks and charges between sessions, that's a non-issue. For someone flying transatlantic, it's a genuine limitation.
Side-by-Side: Which Should You Choose?
• Best for battery life → Picun Active Noise Cancelling. Its 40-hour headline figure and 10-minutes-for-4-hours fast charge beat the G300's 20-hour listed average.
• Best for gaming and casual media → ATTACK SHARK G300. The purple finish, flat-folding 90° cups, and immersive stereo tuning fit a gaming desk setup better.
• Best for air travel and commuting → Picun Active Noise Cancelling. The 95% ANC claim plus AI ENC call clarity is aimed squarely at noisy transit.
• Best for call and video-conference clarity → Picun Active Noise Cancelling. Dedicated AI ENC microphone technology tips this one.
• Best for flat-pack portability → ATTACK SHARK G300. 90° inward rotation means it lies flatter in a bag than the Picun's swivel design.
• Best for wired PC use → Tie. Both include a 3.5mm jack and Bluetooth 5.3, so either works.
• Best for lighter weight → Picun Active Noise Cancelling. At 200 g, it's built for fatigue-free all-day wear.
• Best for a distinctive look → ATTACK SHARK G300. Purple leather-and-plastic is a statement; the Picun is understated black.
In my opinion, the Picun Active Noise Cancelling is the smarter buy for most people. The 40-hour battery claim, 10-minute fast-charge, Hi-Res certified 40mm drivers, AI ENC microphone, and 200 g memory-foam build cover travel, office, gym, and home use in one package. The G300 is a solid, comfortable alternative if you want a flat-folding, purple, gaming-leaning headset and can live with a 20-hour battery. But if you're only buying one, I'd go Picun — it does more of the things most buyers actually need.
Both claim to reduce external noise by up to 95% via active noise cancellation, so the specs are effectively tied. The Picun adds AI ENC microphone noise reduction on calls, which gives it a slight edge for phone and video use.
Picun advertises up to 40 hours of playtime plus a 10-minute charge for 4 hours of listening; its spec sheet lists a 4-hour "average life" figure and a 2.5-hour full charge time. The G300 lists a 20-hour average battery life with no fast-charge feature advertised.
Picun lists a 200 g weight with memory foam ear cups and a self-adjustable headband. ATTACK SHARK uses protein leather and elastic sponge with a 90° inward-rotating cup design. Both are built for comfort, but the Picun's lighter listed weight suits longer sessions.
