- 32GB built-in memory allows for offline MP3 playback without a phone

Who it fits
Good fit for
You will likely appreciate these if you swim regularly or run in wet conditions. The IPX8 rating and bone conduction technology let you stay aware of your surroundings while listening to music stored on the device. The 10+ hour battery life suits long training sessions or multi-day trips. The open-ear design ensures comfort during extended wear, making it a solid choice for athletes who need durability and situational awareness during their workouts.
Who should skip it
You should look elsewhere if you need high-fidelity audio isolation or expect Bluetooth to work underwater. The data confirms that Bluetooth signals cannot transmit through water, so you must use the built-in memory for swimming. If you prefer in-ear seals for noise cancellation, the open-ear bone conduction design will not block outside noise. Additionally, the 32GB storage limit may be insufficient if you maintain a very large music library that exceeds this capacity.
Verdict: These headphones offer a practical, spec-driven solution for swimmers and active users who need waterproof durability and offline music storage. The combination of IPX8 resistance and bone conduction makes them a specialized tool rather than a general-purpose audio device.
Key specs explained for KESIEME
Form Factor: Bone Conduction
This design transmits sound through vibrations to your inner ear, leaving your ear canals open. You remain aware of traffic and conversations, which is safer for running or cycling. It also prevents ear fatigue during long sessions. If you need situational awareness or have sensitive ear canals, this open-ear approach offers a comfortable alternative to traditional in-ear buds.
Water Resistance: IPX8
An IPX8 rating means the headphones can withstand submersion in water, specifically up to 2 meters deep. This makes them suitable for swimming in pools and handling intense sweat without damage. You do not need to worry about rain or accidental drops in water. This level of protection is essential for aquatic sports where standard water-resistant gear would fail.
Connectivity: Bluetooth 5.4, 32GB Built-in Memory
Bluetooth 5.4 provides stable wireless connections for phone-free listening on land. The 32GB internal memory allows you to store music directly on the device. You can switch to MP3 mode for underwater use, as Bluetooth signals do not travel through water. This dual capability lets you swim without a phone, reducing clutter and ensuring uninterrupted audio during workouts.
Battery Life: Up to 10+ hours
The 200mAh battery delivers over ten hours of playback at 60% volume. This duration covers multiple long swims or several days of moderate use. USB-C charging takes about two hours for a full power-up. This capacity ensures you rarely need to recharge during extended training blocks, making it reliable for daily athletes who need consistent performance without frequent interruptions.
Design and build overview
The listing describes the KESIEME x7s as having a wraparound titanium frame. This material choice supports the open-ear bone conduction design. You wear the device by resting the transducers on your cheekbones. Your ear canals remain open to ambient sound. This layout keeps you aware of traffic and conversations during runs or rides. The structure avoids inserting anything into your ears, which reduces fatigue over long sessions.
According to the listing, the unit weighs 1.31 ounces. This light weight helps maintain a secure fit without slipping during vigorous movement. The titanium frame provides flexibility, allowing the headphones to adapt to different head shapes. The finish is black, offering a neutral look for gym or outdoor use. The design prioritizes function over aesthetics, focusing on comfort and stability.
The device lacks ear tips or in-ear seals. Instead, it relies on the wraparound form to stay in place. You can wear it with or without a swim cap. The open design also allows sweat to evaporate quickly, preventing moisture buildup. This makes the build suitable for swimming and intense workouts. The titanium construction is durable yet lightweight, ensuring you can wear it for extended periods without discomfort. The simple, uncluttered design means there are fewer parts to break or clog with water.
Setup and daily use guide
Setting up the KESIEME x7s involves charging the device via its USB-C port. The listing states a full charge takes about two hours and provides up to ten hours of playback at sixty percent volume. The 200mAh battery supports extended sessions for running, cycling, or swimming. For connectivity, the headphones use Bluetooth 5.4. This version offers stable wireless pairing for everyday listening, calls, and workouts when you carry your phone. You can also switch to MP3 mode by using the 32GB of built-in memory. This feature allows you to download music directly to the headphones. This mode is essential for underwater use because Bluetooth signals do not transmit through water. The IPX8 rating confirms the device can withstand submersion up to two meters. You can listen to stored tracks while swimming without needing your phone nearby. The open-ear design means you do not insert anything into your ear canal. This keeps your ears open to ambient sounds like traffic or conversations. The lightweight titanium frame ensures a secure fit during movement. Weighing 1.31 ounces, the black model is comfortable for daily wear. You can use these headphones for sports, running, or general indoor and outdoor activities. The combination of wireless Bluetooth and offline MP3 mode gives you flexibility. You choose the connection method based on your environment and whether you are carrying your phone.
Before you buy these
You should verify that your music library is compatible with standard MP3 formats before downloading tracks to the 32GB internal storage. Since Bluetooth signals do not transmit through water, you must switch to MP3 mode for underwater listening. This device pairs well with most smartphones via Bluetooth 5.4, but ensure your device supports the necessary file types. Regular upkeep involves rinsing the titanium frame with fresh water after saltwater exposure to prevent corrosion. Keep the USB-C port dry during charging. This model fits alongside other open-ear options by offering dedicated swimming capabilities. Unlike standard earbuds, it leaves your ears open for situational awareness. It complements general sports headphones by adding a waterproof variant for lap swimming. You need a separate waterproof case for safe storage when not in use. Ensure your swim cap fits comfortably over the transducers to maintain stability during vigorous strokes.
Check before you buy
- Confirm MP3 compatibility for offline music storage.
- Check swim cap fit over the frame.
- Verify Bluetooth 5.4 support on your phone.
- Rinse with fresh water after saltwater use.
