If you want a neckband headset with a stated 13-hour battery life and IPX7 protection, choose Keenso Neckband Headset; if you need an open-ear design for swimming and greater awareness of your surroundings, choose Sport Headphones Swimming Headphones Open-Ear. For audiophiles, the practical choice comes down to whether a familiar in-ear fit and longer specified playtime matter more than an open fit built around active use.
• Keenso Neckband Headset: IPX7 protection, in-ear placement, and up to 13 hours of talk or music time. Trade-off: it sits in the ears, so it does not offer the open-ear awareness of the Sport Headphones.
• Sport Headphones Swimming Headphones Open-Ear: Open-ear hooks and a flexible neckband are designed for active movement while leaving the ears uncovered. Trade-off: its listed details do not give a battery-life figure or an IPX rating.
• Keenso is for listeners who want stated battery endurance, push-button controls, and a neckband headset for workouts and everyday Bluetooth listening.
• Sport Headphones are for swimmers and outdoor exercisers who prioritize an open-ear design and staying more aware of their surroundings.
Keenso makes the stronger case for someone who wants a straightforward wireless headset for music, calls, and exercise. Its in-ear earpieces connect through a flexible neckband, while push buttons let you adjust volume, skip tracks, or answer calls without reaching for your phone. The listed Bluetooth 5.1 connection is described as reaching about 33 feet, which gives you some room to move around while a paired device stays nearby.
Battery life is the clearest advantage on the spec sheet: Keenso is listed for up to 13 hours of talk or music time, with a 150mAh battery. That figure will appeal if you would rather spend less time planning around charging between workouts or listening sessions. The headset also has an IPX7 rating, stated as protection against sweat and rain. Those details make it a plausible fit for running, cycling, hiking, or gym sessions where moisture and hands-free controls matter.
Its audio description emphasizes bass and a noise-reduction microphone for calls. That may suit someone who wants an in-ear listening experience and expects to take calls as well as play music. Still, the stated features are not a detailed measure of audiophile sound quality. The in-ear design also means it is not the pick for a listener who wants uncovered ears and more awareness of surrounding activity.
Who should skip it: Skip Keenso if an open-ear fit is essential, or if your decision depends on a stated swimming-specific rating rather than the listed IPX7 protection against sweat and rain.

Swimming is part of the product’s intended use, alongside gym training, cycling, running, and other outdoor sports. The description says the headphones are made to withstand wind, rain, and splashes, and calls them water-resistant. However, the listed specifications do not provide an IPX rating or explain a specific limit for underwater use. I would not treat the word “swimming” in the product name as a substitute for a precise waterproof rating when that detail is important to your decision.
The supplied details list Bluetooth 5, a 33-foot connection range, push-button controls, and a one-hour charging time. They also identify a 13mm dynamic driver, but do not state a battery runtime. So the Sport Headphones give shoppers useful information about fit, connection, controls, and charging, but less detail about how long they can play between charges. Their open-ear layout is also a meaningful trade-off: it favors awareness over the more enclosed listening experience of Keenso.
Who should skip them: Skip the Sport Headphones if you need a stated long battery runtime, a defined IPX rating, or an in-ear design that keeps the ear covered.
• Best for a stated battery runtime → Keenso Neckband Headset. Its listed figure is up to 13 hours for talk or music. The Sport Headphones’ specifications give a charging time but no playback runtime.
• Best for an open-ear fit → Sport Headphones Swimming Headphones Open-Ear. The ear hooks leave the ears uncovered, which is useful if maintaining awareness matters during outdoor exercise.
• Best for a clearly stated moisture rating → Keenso Neckband Headset. Its IPX7 rating is specified, with sweat and rain named as relevant conditions. The Sport Headphones are described as water-resistant, but no IPX rating appears in the details.
• Best for swimming-oriented use → Sport Headphones, with a specification caveat. Swimming is explicitly among their intended activities, but the provided data does not spell out an IPX level or underwater-use limit. Check that detail before relying on them for pool use.
• Best for taking calls during a workout → Keenso Neckband Headset. Its description specifically mentions a noise-reduction microphone and call handling through the headset buttons.
• Best for someone who wants quick controls on the headset → Either, with different stated strengths. Both list push-button controls; Keenso also specifies volume, track, and call functions.
• Best for an in-ear listening preference → Keenso Neckband Headset. Its earpieces are listed as in-ear, while the Sport Headphones are built around open-ear hooks.
• Best for a stated charge-time detail → Sport Headphones Swimming Headphones Open-Ear. Their listed charging time is one hour. That does not reveal their runtime, so it answers only part of the battery question.
Buying Considerations
The key decision is not simply which one sounds more suited to sports. It is whether you want an in-ear headset with a stated runtime or an open-ear design centered on situational awareness. Keenso provides more concrete battery and protection information. The Sport Headphones provide a more specific fit story for outdoor activity and swimming, but leave important battery and waterproofing details unstated.
If you are looking for the best open ear earbuds for audiophiles, the Sport Headphones are the only one of these two with an open-ear design. Their hooks and flexible neckband are intended to help them stay put during movement, while the uncovered-ear layout supports awareness. But audiophile shoppers should keep expectations grounded: the data identifies a 13mm dynamic driver and gives a few audio figures, yet does not establish how the headphones will sound across different music or listening environments.
Comfort is also a personal fit question, not something a product description can settle for every listener. Keenso lists an ergonomic, flexible neckband and soft materials; Sport Headphones list lightweight construction, ear hooks, and a flexible neckband. If your search is for the best comfortable earbuds for audiophiles, consider which placement you prefer: in-ear earpieces or open-ear hooks. Neither description provides a fit measurement or a guarantee that every ear shape will feel comfortable over a long session.
Finally, confirm the details that matter most to your routine. If swimming is a must, look for a clear water-use rating rather than relying only on a product name or broad water-resistance language. If long sessions matter, Keenso’s 13-hour figure is useful; the Sport Headphones do not have a listed runtime here.

I would choose Keenso Neckband Headset for audiophiles who want the more fully specified everyday option: an in-ear fit, IPX7 rating, call-focused microphone description, and up to 13 hours of stated playtime. Those concrete details make it easier to match the headset to workouts and longer listening sessions.
I would choose the Sport Headphones instead when open-ear awareness is the priority, particularly for outdoor exercise. Their swimming-oriented positioning may appeal, but I would first confirm the waterproofing details because no IPX rating or underwater-use limit is listed.
FAQ
Keenso is listed for up to 13 hours of talk or music time. The Sport Headphones list a one-hour charging time but do not provide a playback-runtime figure, so their battery life cannot be compared from the given specifications.
Swimming is included among their intended uses, and the description says they can withstand wind, rain, and splashes. However, no IPX rating or specific underwater-use limit is provided, so confirm that information before using them in a pool.
The Sport Headphones’ open-ear hooks are designed to keep the headset in place while allowing more awareness of the surroundings. Keenso is also described for running and cycling, but its in-ear fit does not offer the same open-ear layout.
The available details do not establish that one has objectively better sound quality. Keenso’s description emphasizes bass and noise-reducing call audio; the Sport Headphones list a 13mm dynamic driver but provide limited information about their sound profile. Choose based on fit and use case rather than assuming either is an audiophile-grade option.
