If you want over-ear noise reduction and long listening between charges for swimming-related travel, choose Ko-Star Hybrid Active NoiseCancelling; if you need an open-ear clip-on design that keeps you aware of your surroundings, choose Linklike C-Flow Couture. Neither product is described as waterproof, so I would not use either in the water.
The difference is practical: Ko-Star surrounds the ears and offers hybrid ANC, while Linklike leaves the ears open and trades noise cancellation for awareness. Here is how those designs translate to everyday listening.

Ko-Star Hybrid Active NoiseCancelling vs Linklike C-Flow Couture at a Glance
• Ko-Star’s biggest strength: over-ear hybrid ANC, transparency mode, and up to 60 hours of playback with ANC off. Trade-off: its ear-covering design is less open to surrounding sound, and water resistance is not specified.
• Linklike’s biggest strength: a light open-ear clip-on design, 70 hours of total playtime with the case, and Bluetooth multipoint. Trade-off: it has no noise cancellation and does not seal around the ears.
• Choose Ko-Star if you want a quieter listening setup for travel, work, or home, plus the option to hear nearby sounds through transparency mode.
• Choose Linklike if you want open-ear listening, a clip-on fit, and awareness of your surroundings during everyday activities.
• For swimming, neither is a swim headphone: the supplied specifications do not state that either product is waterproof or intended for use in water.
Ko-Star is the over-ear choice. Its hybrid active noise cancellation is specified to reduce low-frequency ambient noise by up to 30 dB, with airplane cabin noise, traffic, and office chatter given as examples. That design points toward flights, desk work, or listening at home when you want less background sound competing with your audio. Transparency mode provides the opposite option: you can let surrounding sounds through without taking the headphones off.

The trade-off is the physical format. These are over-ear headphones with memory-foam cups, not compact clip-on earbuds, and their ANC is a poor match for anyone who specifically wants to hear the environment continuously. I would consider them for travel and indoor listening, not for swimming: the product information does not specify water protection.
Skip Ko-Star if you need an open-ear design, or if your swimming routine requires headphones rated for use in water.
Linklike takes a different approach: these are open-ear clip-on earbuds rather than sealed, over-ear headphones. The described Z-Structure and flexible memory-wire bridge are intended to distribute the fit around the ear, and each earbud is specified at 4.7 g. That light clip-on format may appeal to someone who dislikes covering the ears or wants to remain more aware of sounds around them. The product description explicitly says it has no noise cancellation, so openness is a defining feature, not a missing mode to overlook.
For listening away from a charging outlet, Linklike lists up to 9 hours of playback on a single charge and 70 hours total with the charging case. It uses Bluetooth 6.0 and supports dual-device multipoint, which is useful if you alternate between a computer and phone. Its 13 mm dynamic driver, LDAC support, and Hi-Res audio claims are aimed at listeners who want detailed wireless playback; these details do not change the open-ear design or provide noise isolation.
The Couture version also has detachable zircon earrings and a concealed storage arrangement integrated with the earbuds and case. That decorative detail will matter to some buyers and be irrelevant to others. The main trade-off is that open-ear listening does less to block nearby sound than Ko-Star’s ANC-equipped over-ear design. Linklike lists environmental noise cancellation for calls, but that is not the same as cancelling ambient sound for the listener. It is not specified as waterproof, either.
Skip Linklike if you want strong isolation from surrounding noise or need a product explicitly designed for swimming.
Side-by-Side: Which Should You Choose?
• Best for reducing background noise while listening → Ko-Star Hybrid Active NoiseCancelling. It has hybrid ANC specified to reduce low-frequency sounds, plus a transparency mode when you want to hear what is around you.
• Best for stated playback on one charge → Ko-Star. The listed maximum is 60 hours with ANC off and 40 hours with ANC on, compared with Linklike’s 9 hours per charge.
• Best for stated total playtime including the case → Linklike. Its combined figure is up to 70 hours, though that includes the charging case rather than a single uninterrupted charge.
• Best for over-ear comfort features → Ko-Star. Its adjustable headband and memory-foam ear cups are intended for an over-ear fit during extended listening.
• Best for a light clip-on format → Linklike. Each earbud is listed at 4.7 g and uses a flexible memory-wire bridge.
• Best for moving between phone and computer → Either. Both specify Bluetooth 6.0 and dual-device connection, though the designs and listening experience differ.
• Best headphone for swimming → Neither, based on the provided specifications. No water-resistance rating or swimming-use claim is given for either model.
The phrase “for swimming” needs a careful distinction. A headphone can be convenient for the trip to a pool without being suitable to wear in the water. Ko-Star’s over-ear cups and Linklike’s open-ear clip-on shape describe how they fit; neither fact establishes water protection. Since no waterproof specification is listed, I would keep both away from swimming and choose a product with clearly stated swimming suitability for actual pool use.
That also affects searches for the best ear clip headphones for swimming. Linklike is the only one here with a clip-on design, but its product details do not say it is made for swimming. The shape alone is not enough to make it a swim headphone. Likewise, Ko-Star’s ANC and long battery life may be useful around travel to a pool, but they do not make its over-ear design suitable for immersion or splashes.
Think about what you want to hear. Ko-Star is the more focused option when blocking background noise matters, with transparency mode available for brief awareness without removing the headset. Linklike is the more naturally open option, but it intentionally lacks noise cancellation. Its environmental noise cancellation applies to calls, not to quieting the audio environment for the listener.
Battery figures also describe different things. Ko-Star’s 60-hour maximum is with ANC off; with ANC on, the specified maximum is 40 hours at 50% volume. Linklike’s 9-hour figure is per charge, while 70 hours includes the case. Those are useful reference points, but they are not directly identical measures of uninterrupted listening.
My Verdict
I would choose Ko-Star for everyday listening when I want over-ear coverage, adjustable noise reduction, transparency mode, and long playback. Linklike is the more appealing pick if open-ear awareness and a lightweight clip-on design matter more than blocking noise.
For swimming, though, I would buy neither based on the listed information. Neither is specified as waterproof or intended for use in water, and I would want that clearly stated before choosing swim headphones.
