If you want a featherlight open-ear headphone built for running, cycling and staying aware of traffic day or night, choose HAKII Light 2; if you need a full size over ear headphone for everyday music, gaming and calls around the house or office, choose Core Innovations Over-Ear Headphones.
• HAKII Light 2, biggest strength: a 26g open-ear fit with a 180° beacon light in three modes, IPX5 sweat and splash resistance, and 16 hours of playtime on a 1-hour charge.
• HAKII Light 2, biggest trade-off: it does not seal or cup your ears at all, so nothing blocks outside noise — and there is no jack, so you are fully dependent on Bluetooth.
• Core Innovations Over-Ear Headphones, biggest strength: a true full size over ear design with soft cushions, deep bass tuning and a built-in mic, in a classic sealed format that works with most Bluetooth devices.
• Core Innovations Over-Ear Headphones, biggest trade-off: 10 hours of battery and a 2-hour charge, plus a shorter 90-day warranty window on the unit, with no lighting and no water-resistance rating listed.
• Who each pick is for: HAKII Light 2 for runners, cyclists and outdoor athletes in the dark; Core Innovations for desk, couch and commute listeners who want a full size over ear headphone.
The HAKII Light 2 is not really a "sit at your desk" headphone. It is a piece of outdoor gear that happens to play music. The headline design choice is the open-ear format: nothing goes inside your ear canal and nothing clamps over it. That means traffic, footsteps, a cyclist's bell and a training partner's voice all stay audible while your audio plays. If you have ever pulled an earbud out at a crosswalk, you already understand the point of this shape.
The second design choice is the 180° Ultra-Bright Beacon String with three lighting modes. Combined with the orange finish, the intent is obvious — being seen, not just hearing. For night runs, early winter rides or walking on unlit roads, that is a genuinely different feature class from what most headphones offer.
Buy it if you train outdoors, care about being visible and aware, and want an ultralight fit that disappears on your head. Skip it if you want isolation — on a plane, in a noisy open office or on a train, the open-ear design gives you zero passive blocking, and there is no active noise control either.
Core Innovations Over-Ear Headphones: Who It's For
The Core Innovations pair is the classic shape most people picture when they say "headphones." Full size over ear cups, soft cushions, a padded headband, and a sealed fit that sits around your ears rather than in or beside them. That format does something the HAKII cannot: it physically surrounds your ear, which naturally softens some of the room around you even without any noise-cancelling circuitry. The data sheet lists the enclosure as faux leather, plastic, polycarbonate, rubber and silicone — in other words, the usual mix of soft touch surfaces and a rigid frame that this category is built from.
Connectivity is Bluetooth 5.4 with easy pairing and tangle-free wireless listening, and it works with most Bluetooth devices. There is a built-in microphone for calls, and the tuning is described as deep bass with clear audio from a dynamic driver. Battery life is rated at 10 hours with a 2-hour charge.
Weight is listed at 0.25 kg — roughly a quarter of a kilogram — which is normal territory for a full size over ear headphone and a world away from the 26g HAKII. The unit carries a 90-day warranty on purchase with 1 year for parts and labor, and the age guidance is teen, so it is pitched at a general listener rather than a dedicated athlete.
Buy it if you want a comfortable, sealed, over-ear headphone for music, gaming, video calls and laptop work, and you like the classic look. Skip it if you need long battery life, water resistance, or any kind of visibility or awareness feature while you move.
• Best for running and cycling → HAKII Light 2. Open-ear awareness plus the beacon light and IPX5 rating are built for exactly this.
• Best for night visibility → HAKII Light 2. Three lighting modes on a 180° beacon string, plus the orange colorway.
• Best for battery life → HAKII Light 2. 16 hours versus 10, and it refills in 1 hour instead of 2.
• Best for all-day comfort weight → HAKII Light 2. 26g with a flexible titanium frame and silicone contact points.
• Best for a full size over ear fit → Core Innovations Over-Ear Headphones. Sealed cups and soft cushions are the whole point of this design.
• Best for desk, gaming and office calls → Core Innovations Over-Ear Headphones. Built-in mic, Bluetooth 5.4, universal compatibility, over-ear isolation.
• Best for water and sweat resistance → HAKII Light 2. IPX5 is stated; nothing comparable is listed for the Core Innovations pair.
• Best for casual home listening on a budget-conscious setup → Core Innovations Over-Ear Headphones. A straightforward over-ear wireless headphone with no extra features to pay for — check the current price on Amazon before deciding.
In my opinion, these two are not competing for the same buyer, so I would pick based on where the headphones will live. If most of my listening happens while moving outdoors — runs, rides, walks after dark — I would buy the HAKII Light 2. The open-ear awareness, the beacon light, the IPX5 rating and 16 hours of battery are all pointed at that one job, and 26g on your head is a real comfort advantage over a long session.
If I want one pair for the couch, the desk, gaming and calls, I would buy the Core Innovations Over-Ear Headphones. Full size over ear cups with soft cushions and a built-in mic are simply the better tool for that room. Just go in knowing it is a 10-hour, 2-hour-charge headphone with no water rating and a shorter unit warranty window.
On the Core Innovations pair, the cups should sit fully around your ears with the soft cushions resting against your head, not pressing on your ear cartilage — the over ear shape and cushioned design are meant for that seal. The HAKII Light 2 is the opposite approach: it sits outside the ear canal entirely with a flexible titanium band, so it should feel almost weightless rather than clamped.
That depends far more on the battery and build than on the shape. The Core Innovations Over-Ear Headphones are rated for 10 hours per charge with a 2-hour charge time, while the HAKII Light 2 is rated for 16 hours with a 1-hour charge. On the warranty side, HAKII lists 1 year, and Core Innovations lists 90 days on purchase with 1 year for parts and labor — worth weighing if you use them daily.
For stationary listening, in my opinion yes. A full size over ear design like the Core Innovations pair surrounds the ear, spreads pressure across soft cushions and includes a built-in mic for calls — a better fit for work, gaming and long listening sessions. If your priority is outdoor training, awareness and staying visible at night, the open-ear HAKII Light 2 is the more sensible pick.
Not automatically. The Core Innovations Over-Ear Headphones have no water-resistance rating listed in their specs, so I would keep them away from rain and heavy sweat. The HAKII Light 2 carries an IPX5 rating, which covers sweat and water splashes — useful for workouts and light rain, though it is not a claim of full immersion protection.
