If you want open-ear headphones with a simple Bluetooth setup for running, choose KOAIEZ IP7; if you need onboard music and a swimming-focused waterproof design, choose Soveign Waterproof Headphones. The key difference is straightforward: KOAIEZ emphasizes everyday wireless workouts, while Soveign adds MP3 playback and an IPX8 rating for use in water. Neither feature set is a universal win; the right one depends on where and how you plan to move.
KOAIEZ IP7 vs Soveign Waterproof Headphones at a Glance
• KOAIEZ IP7’s strength: Open-ear bone-conduction listening, Bluetooth 5.3, and a stated 6–10 hours of battery life; trade-off: it doesn’t list onboard MP3 storage for listening without a Bluetooth connection.
• Soveign’s strength: IPX8 water protection and 32GB of memory for MP3 playback; trade-off: Bluetooth is limited in water, so swimming calls for MP3 mode.
• KOAIEZ IP7 is for runners and other active listeners who want wireless audio, calls, and an open-ear fit without carrying stored music on the headphones.
• Soveign is for swimmers and athletes who value music stored on the headset and can use separate MP3 and Bluetooth modes.
• If you mostly run outside or move between workouts and calls, I’d lean KOAIEZ IP7. If swimming is central to your routine, Soveign’s features are more specifically suited to that use.
KOAIEZ IP7 is an open-ear, bone-conduction-style sports headset with Bluetooth 5.3. Its sound is described as reaching the inner ear through the cheekbone, and its open design leaves the ear uncovered. For a run, that means you can listen without plugging your ear canals. It’s a practical format for someone who wants audio while staying aware of surrounding sounds, although the open-ear design is not the same thing as an adjustable transparency mode.
The headset has a flexible neckband wrapped in rubber, with loops that sit over the ears to help hold it in place. That combination is aimed at movement: the design is meant to stay put during workouts rather than dangle like ordinary earbuds. The manufacturer describes its silicone as skin-friendly and the body as lightweight and easy to carry. Bluetooth pairing and multi-pairing are listed, along with a 10-meter transmission range. Those details make it a plausible fit for someone moving around a gym or keeping a phone nearby while exercising.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Battery life is listed as 6–10 continuous hours, with a two-hour charge. That range can cover many individual runs and workouts, but it is not a guarantee of the same runtime in every situation. The headset also has microphones for calls, and its stated IPX7 water-resistance rating makes it relevant for sweat and wet-weather exercise. Still, its feature list does not name onboard music storage, and the battery figure is more limited than the much longer runtime sometimes suggested by the product information elsewhere. I would use the explicit 6–10-hour figure as the grounded planning number.
Who should skip it: Skip KOAIEZ IP7 if you want stored MP3 playback for swimming or need a headset whose listed protection is IPX8.
Soveign’s main distinction is that it combines an open-ear bone-conduction design with IPX8 water protection and a built-in 32GB MP3 player. The product information says to use MP3 mode when swimming because Bluetooth is limited in water. That detail matters: the headset is not simply a Bluetooth pair of headphones that works normally beneath the surface. You need compatible music stored on the device and should expect to switch modes for swimming.
For a runner, the onboard memory can also be useful when leaving a phone behind is part of the plan. The listed storage is 32GB, and the product describes MP3 mode as holding more than 6,000 songs. That is a stated capacity claim, not a guarantee of how many tracks any particular collection will fit. It does provide a clear contrast with KOAIEZ IP7, whose listed features do not include internal storage. Soveign also supports Bluetooth 5.3, so it offers a wireless mode for ordinary use outside the water.
The headset has physical buttons for functions such as volume and answering calls, with one-handed operation described. That may appeal to someone who prefers tactile controls during exercise. It is also described as flexible and bendable, with a fit that can be adjusted. The trade-off is that its swimming-focused setup involves a mode distinction and stored MP3 files; those features add capability, but they may be unnecessary complexity for a person who only wants a straightforward headset for land-based runs. Its information does not provide a battery-life figure, so I wouldn’t assume it lasts longer than KOAIEZ based on the available specifications.
Who should skip it: Skip Soveign if you don’t need MP3 storage or swimming protection and would rather choose a simpler running headset with a stated battery-life range.
• Best fit for Bluetooth-first running → KOAIEZ IP7. Bluetooth 5.3, multi-pairing, and a stated 10-meter transmission range suit workouts where your phone remains nearby.
• Best fit for swimming → Soveign. Its IPX8 rating and MP3 mode address swimming more directly; Bluetooth is limited underwater, so the product specifies MP3 mode for that use.
• Best for a stated battery estimate → KOAIEZ IP7. Its listed 6–10 hours of continuous use and two-hour charge give you figures to plan around. Soveign’s supplied details don’t state battery life.
• Best for phone-free stored music → Soveign. The 32GB memory and MP3 mode let you play audio stored on the headset rather than relying on a Bluetooth connection.
• Best for calls while moving → KOAIEZ IP7. Its product information specifically mentions built-in microphones and clear-call use. Soveign lists call-answering controls, but its details don’t describe microphone performance.
• Best for someone who wants open ears → Both. Both are described as open-ear bone-conduction headphones, so neither is a conventional sealed in-ear design.
• Best for tactile controls → Soveign. Physical buttons are listed for volume and call answering, which may be easier to locate by touch than controls that depend on a particular gesture.
• Best for an extra bass headphone for running → Neither is established by the listed specs. KOAIEZ describes fuller sound and clear midrange and high frequencies, but neither product provides a bass measurement or a supported claim that it is tuned for extra bass.
Start with where you’ll actually listen. If your routine is mainly road, trail, or gym running, KOAIEZ IP7’s open-ear format and Bluetooth features are a direct match for that kind of use. Its battery estimate is useful for planning, and the over-ear loops and neckband are intended to hold the headset in place as you move. If your sessions are long, remember that the stated range is 6–10 hours rather than an unlimited runtime.
If swimming is part of the routine, Soveign has the clearer feature match on paper. Its IPX8 rating and whole-body waterproof description are intended for water use, but you still need to follow the MP3-mode instruction because Bluetooth is limited in water. That means preparing stored audio rather than expecting your phone’s Bluetooth connection to behave as it does on land. For someone who runs and swims, that split may be worthwhile; for someone who never enters the water, the storage feature may not carry much weight.
Think about what “open ear” means for your needs, too. Both products leave the ears uncovered, but neither is described as having a selectable transparency mode. If you’re searching for “transparency mode gaming headphones for running,” these are not presented as gaming headsets, and the available specifications don’t identify a transparency-mode control. Their open-ear construction can leave the ears unobstructed, but that is a different feature from electronic transparency processing.
Finally, decide whether a listed battery figure or built-in music storage matters more. KOAIEZ supplies a runtime range and charge time; Soveign supplies storage capacity and an MP3 mode. The available details don’t establish which has better sound quality overall, more bass, or longer battery endurance. I would choose based on the features that fit your actual workouts rather than infer performance the specifications don’t document.
For running, I would choose KOAIEZ IP7 if my routine were mostly land-based and I wanted Bluetooth, an open-ear fit, and a stated 6–10-hour battery range. Its design and features line up with that everyday use without requiring stored MP3 files. I’d choose Soveign instead if swimming and phone-free MP3 playback were priorities, because its IPX8 rating and 32GB storage are the more relevant strengths for those needs.
For ordinary Bluetooth-based runs, KOAIEZ IP7 is the more direct fit: it lists Bluetooth 5.3, multi-pairing, call microphones, and a 6–10-hour runtime. Soveign may suit runners who specifically want MP3 music stored on the headset.
Can I use Soveign Waterproof Headphones while swimming with Bluetooth?
Neither product’s listed features identify an electronic transparency mode. Both are described as open-ear bone-conduction designs, which leave the ears uncovered but are not the same feature as a selectable transparency setting.
KOAIEZ IP7 lists 6–10 hours of continuous use and a two-hour charge. The supplied Soveign details do not give a battery-life figure, so there isn’t enough information to compare their runtimes.
