If you want wireless headphones for everyday workouts, choose Bose SoundSport; if you need headphones built for swimming, choose H2O Audio Interval Swim Headphones. For exercise on dry land, Bose’s workout-focused fit and sweat and weather resistance make the simpler choice. For laps and underwater sports, H2O Audio’s waterproof design and goggle attachment solve a different problem.
The key distinction is not a small feature gap: Bose is an in-ear Bluetooth workout headphone, while H2O Audio is designed around swimming and an open-ear bone-conduction format. I’d choose based on where you exercise, not on which one sounds more versatile on paper.
• Bose SoundSport: A workout-oriented fit, sweat and weather resistance, and balanced sound at different volume levels; the trade-off is that its stated battery life is 6 hours and the supplied details do not describe it as suitable for submersion.
• H2O Audio Interval Swim Headphones: IPX8 waterproofing, bone conduction, and goggle loops make it swim-focused; the trade-off is that the design is specialized for water use rather than a conventional in-ear workout fit.
• Bose SoundSport is for: People who mainly exercise on land and want Bluetooth audio with Stay Hear+ tips.
• H2O Audio Interval is for: Swimmers who want headphones that attach to goggles and are designed for underwater use.
Bose SoundSport makes the most sense for someone whose exercise routine happens at the gym, on a walk, or in another setting where sweat and weather are the main concerns. Its Stay Hear+ tips are intended to help keep the earbuds in place during workouts, and the rounded-tip, over-ear placement gives it a conventional earbud-style setup. Bose also describes the sound as balanced across volume levels, which is a useful quality for people who adjust volume as their environment changes.
Bluetooth and NFC pairing, with voice prompts, are aimed at making setup straightforward. The stated Bluetooth range is 10 meters, and the battery life is 6 hours. Those numbers suggest a practical fit for many individual exercise sessions, though I would not choose it over a longer-lasting option if extended listening time is the priority. The listed Bluetooth version is 4.1.
I’d consider Bose for land-based exercise when a secure-feeling earbud fit and sweat and weather resistance are more relevant than underwater capability. I’d skip it for swimming: the available product details describe resistance to sweat and weather, not waterproofing for submersion. And if your priority is an open ear headphone for exercise, note that Bose’s design is an in-ear style rather than an open-ear format.
H2O Audio Interval is the more focused choice for swimmers. Its IPX8 waterproof rating and stated suitability for submersion up to 12 feet (3 meters) distinguish it from a general workout earbud. The design uses bone conduction and sits open-ear, while integrated goggle loops let you attach the device to swim goggles. The stated goal is a low-drag fit in the water.
The product is also designed to work with an Apple Watch attached to the Interval. Its Bluetooth connection is listed as Bluetooth 5, and its battery life is 7 hours. The supplied details mention media controls for volume, play, pause, and skipping audio, as well as five sets of elastomer earplugs in sizes from XS to XL. Those are useful fit and control details for a swim-focused setup, but they do not turn it into a conventional all-purpose earbud.
I’d choose H2O Audio if swimming is a regular part of your exercise routine and the goggle attachment and waterproofing match how you train. I would not pick it just because “open ear” sounds appealing: this is a specialized swimming product, and the available specifications do not establish it as the better choice for every land workout. It may also be the wrong fit if you want a conventional sealed earbud experience.

Side-by-Side: Which Should You Choose?
• Best for swimming and underwater exercise → H2O Audio Interval. It is listed as IPX8 waterproof and is described for submersion up to 12 feet (3 meters); Bose’s supplied details mention sweat and weather resistance instead.
• Best for attaching headphones to swim goggles → H2O Audio Interval. Integrated goggle loops are a central part of its water-focused design.
• Best for a stated battery-life figure → H2O Audio Interval. Its listed average battery life is 7 hours, compared with 6 hours for Bose. That is a one-hour difference on paper, not a guarantee of actual runtime in every situation.
• Best for NFC pairing → Bose SoundSport. Bose’s details specify Bluetooth and NFC pairing with voice prompts; the H2O details specify Bluetooth but do not list NFC.
• Best for an open-ear design → H2O Audio Interval. Its product information identifies an open-ear fit and bone-conduction driver; Bose uses ear tips.
• Best for sweat and weather resistance → Bose SoundSport. That protection is explicitly listed for workouts, though it should not be confused with swim-proof submersion protection.
• Best for someone seeking hi res head phones for exercise → Neither can be established as a hi-res choice from the supplied specifications. The listed information does not identify either product as high-resolution audio equipment, so I would compare them on fit, exercise setting, and water protection instead.
One phrase shoppers sometimes use is best with microphone open ear earbuds for exercise. H2O Audio is the open-ear option, but the specifications provided do not confirm a microphone feature.
For exercise on land, I’d buy Bose SoundSport because its workout-focused tips and stated sweat and weather resistance fit that use more directly. For swimming, I’d choose H2O Audio Interval without hesitation: IPX8 protection and goggle loops address needs Bose’s listed details do not. My recommendation is to match the headphone to the environment first, then weigh the one-hour battery difference and fit style.
The supplied Bose information describes sweat and weather resistance, but does not identify the headphones as waterproof or suitable for submersion. For swimming, H2O Audio Interval is the model explicitly listed as IPX8 waterproof.
It is the clearer fit for swimming and underwater exercise. For land workouts, Bose has workout-oriented Stay Hear+ tips and stated sweat and weather resistance; the right choice depends on where you exercise.
H2O Audio lists 7 hours of average battery life, while Bose lists 6 hours. These are stated figures, so actual runtime can vary with use.
H2O Audio is identified as open-ear and uses bone conduction; Bose is an in-ear design. The supplied information does not specify a microphone for either model, so it cannot confirm that feature.
