• ATTACK SHARK G300 — biggest strength: Active Noise Cancelling paired with Bluetooth 5.3 and a wired 3.5 mm option, so you can cut out office chatter, engine roar or subway rumble and still take calls through the built-in mic.
• ATTACK SHARK G300 — biggest trade-off: It's a sealed over-ear design with a rechargeable battery, so longer listening sessions mean managing charge, and the enclosed earcups trap more heat than a vented design.
• EKSA H27 — biggest strength: A semi-open, breathable build with ENC voice pickup and in-line controls, plus a long 7.22-foot cable that lets you move around your desk without a battery in the equation.
• EKSA H27 — biggest trade-off: Wired-only USB connectivity (USB-C or USB-A) and no active noise cancelling — it keeps you aware of your surroundings rather than blocking them out.
• Who each pick is for: ATTACK SHARK G300 for commuters, travelers and mixed work/play users who want one flexible wireless headset; EKSA H27 for desk-bound workers, call-center staff and anyone who lives in voice meetings all day.
The G300 is the more versatile of the two. It runs Bluetooth 5.3 for wireless listening at up to 33 feet of range, and it also accepts a 3.5 mm jack cable, so you're not locked out if you want a wired connection to a laptop or console. That dual-path connectivity is the real story here: one headset that moves between a phone call on the train, a gaming session at home, and a video meeting at your desk.
Where it earns its keep is noise. The Active Noise Cancelling is rated to reduce external ambient noise, which the spec sheet describes across car and airplane engines, subway rumble, office chatter and construction clatter. A dedicated button lets you flip modes quickly. For anyone working in a noisy home or open-plan space, that's the feature that decides the purchase. The dual 40mm dynamic drivers cover a 20 Hz to 20 kHz range, which points to a full-range tuning with the deep, punchy low end the brand leans into — good for music, movies and games.
Comfort is handled with protein leather earcups over highly elastic sponge, an adjustable headband, and 90° inward-rotating cups for different head shapes. The trade-off is the sealed design: sealed cups isolate better but run warmer over long stretches, and you'll want to keep an eye on charge since a battery is part of the deal. The black leather-and-plastic build is understated enough for an office.
Buy the G300 if you want one headset for commuting, travel and gaming with real noise cancelling and no cable required. Skip it if you want a purely wired, always-ready desk headset and never want to think about charging.
The H27 is a work tool, and it's built like one. It's wired over USB — USB-C or USB-A — so there's no pairing, no dongle, no battery. You plug it in and it works. For a call center or a shared office where you're on back-to-back calls, that reliability matters more than any wireless convenience.
The headline design choice is the semi-open acoustic structure. Instead of sealing you off, it keeps some environmental awareness and uses breathable ear cups to promote airflow, which the spec sheet frames as a way to prevent heat and moisture buildup. That's the opposite philosophy from the G300, and for eight-hour desk shifts it's arguably the smarter one. The adjustable boom mic with ENC (VoicePure) targets precise voice pickup and cancels surrounding noise on your end of the call — the point being that you sound clear, not that your room goes silent.
Controls are in-line: volume, mic mute, and answer/end calls without leaving your workflow. The 7.22-foot cable is generous, which is a small detail that matters a lot if you pace while you talk or reach across a desk. Frequency response spans 200 Hz to 8 kHz with 32 ohm impedance and 139 dB sensitivity — that's a voice-first tuning, not a music-first one, so don't expect the G300's bass presence. It's backed by a 2-year warranty.
Buy the H27 if your day is voice calls, meetings and desk work and you value a wired, breathable, no-battery setup. Skip it if you want noise cancelling, wireless freedom or serious music listening.
Side-by-Side: Which Should You Choose?
• Best for wireless freedom → ATTACK SHARK G300. Bluetooth 5.3 with up to 33 feet of range versus the H27's fixed USB cable.
• Best for all-day breathability → EKSA H27. The semi-open design and airflow-focused ear cups are built for long desk sessions.
• Best for clear voice pickup → EKSA H27. The adjustable boom mic with ENC is purpose-built for calls.
• Best for music, movies and gaming → ATTACK SHARK G300. Dual 40mm drivers and a 20 Hz–20 kHz range suit full-range listening.
• Best for plug-and-play reliability → EKSA H27. USB-C/USB-A wired connection means no charging and no pairing.
• Best for travel and commuting → ATTACK SHARK G300. Noise cancelling and a rotating, adjustable fit travel better.
• Best for call-center and office shifts → EKSA H27. In-line call controls, a 7.22-foot cable and a 2-year warranty fit that job.
For most people reading this, I'd pick the ATTACK SHARK G300. In my opinion it's the more flexible headset: wireless when you want it, wired when you need it, noise cancelling for noisy rooms and travel, and full-range sound that works for music and games too. It covers more of a normal day. I'd only steer you to the EKSA H27 if your job is essentially talking — calls, meetings, call-center shifts — where a wired, breathable, voice-tuned headset with in-line controls is simply the right tool.

how do over ear headphones work
Over-ear headphones rest around your ears rather than on them, using larger drivers to move more air for fuller sound. The ATTACK SHARK G300 seals around the ear with active noise cancelling and dual 40mm drivers, while the EKSA H27 uses a semi-open cup that lets air flow while still delivering audio through its dynamic drivers.
how long do over ear headphones last
Lifespan depends mostly on build and how the battery and pads hold up. The EKSA H27 is wired with no battery to wear out and carries a 2-year warranty, which makes it the more predictable long-term pick. The ATTACK SHARK G300 has a rechargeable battery, so its useful life partly tracks battery health, though its protein-leather earcups and adjustable headband are built to take daily use.
do over ear headphones damage hearing
Any headphones can contribute to hearing strain if you listen too loudly for too long, and that's about volume and duration, not the over-ear format itself. The EKSA H27's semi-open design keeps you aware of your surroundings, which can help you avoid cranking volume. If you use the G300's noise cancelling, you can often listen at lower levels in noisy places.
what are the best over ear headphones
There's no single answer — it comes down to your use case. In my opinion, for a mix of travel, home office and gaming, the ATTACK SHARK G300's noise cancelling, Bluetooth 5.3 and wired 3.5 mm option make it the stronger all-rounder. For an office or call-center desk where clear calls and breathability matter most, the EKSA H27 is the better fit.
