Who it fits
Good fit for
This device suits swimmers and triathletes who want to listen to music without carrying a phone. The 32GB storage is ideal for users who prefer offline music libraries. You will appreciate the IP68 rating if you swim in pools or open water. The bone conduction tech is best for those who need to hear ambient noise for safety. It also works for runners who want secure, lightweight earbuds that do not block ears. The long battery life supports all-day outdoor adventures.
Who should skip it
You should look elsewhere if you need standard Bluetooth earbuds for calls. This model lacks a microphone for phone conversations. It is not suitable for users who want to connect to a phone for streaming services. The IP68 rating is for swimming, not high-pressure water jets. If you prefer in-ear isolation to block out noise, this open-ear design will not work for you. It is also not ideal for users who want a traditional headphone shape with ear cups.
Verdict: The Rhyfell S18 is a specialized tool for swimmers who need offline music and water resistance. It delivers reliable performance for aquatic activities but lacks versatility for general audio use.
Key specs explained for the S18
IP68 waterproof rating
This certification means the device can be fully submerged in water up to 2-5 meters deep. You can use these headphones for swimming in pools or open water without worrying about damage. This level of protection is essential for aquatic sports, allowing you to leave your phone behind and enjoy music directly from the device while submerged.
32GB built-in memory
The headphones include 32GB of internal storage, which holds over 8,000 songs. This allows you to play music independently without needing a paired smartphone. For swimmers or runners who want to travel light, this eliminates the need for cables or a connected device, keeping your focus on your workout while having ample space for your entire music library.
10 hours playtime
The battery provides 10 hours of continuous playback on a single charge. This duration covers long training sessions, such as marathon runs or extended swims, without requiring a mid-activity recharge. Compared to standard models that offer around five hours, this extended stamina ensures the headphones remain powered through your most demanding daily activities and outdoor adventures.
Bluetooth 6.0
This version of Bluetooth offers instant pairing and stable synchronization with your devices. The zero-delay connection ensures audio stays in sync with your movements during running or walking. This technology provides a reliable wireless experience, reducing the frustration of lag or connection drops that can occur with older Bluetooth standards, ensuring consistent audio quality during active use.
28g weight
Weighing only 28 grams, the frame is ultra-lightweight and designed for comfort during extended wear. The low mass reduces pressure on your head and ears, making it suitable for long periods of activity. This ergonomic design helps the headphones stay stable during high-intensity training, ensuring they do not fall off while you are swimming, surfing, or participating in triathlons.
Design and build details
According to the listing, the Rhyfell S18 uses liquid silicone for its frame. This material choice supports the ergonomic fit described for swimmers. The device weighs 0.99 ounces. This light weight helps keep the unit stable during high-intensity training or long periods of wear. You do not need to worry about the headphones falling off while you are in the water.
The physical dimensions are 4 inches in width, 2 inches in height, and 5.5 inches in length. The listing notes a 28-gram frame weight in the features, which aligns with the 0.99-ounce spec. The bone conduction layout leaves your ears open. This design allows you to hear ambient sounds while you swim or surf. It enhances situational awareness for outdoor activities like triathlons.
Two color options are available: Orange and Grey. The listing highlights the open-ear design as a safety feature. You can enjoy music through your cheekbones without blocking your ears. The silicone construction ensures comfort against the skin. This build supports use in pools, oceans, or during land-based workouts. The lightweight and secure fit make it suitable for athletes who need reliable gear that stays in place.
Setup and daily use guide
The Rhyfell S18 offers two distinct ways to use audio, depending on your environment. For pool swimming or surfing, you switch to MP3 mode. This mode relies on the 32GB internal storage. You can transfer over 8,000 songs to the device. The listing states the transfer speed is 18MB/s. This allows you to load your workout library in minutes. You do not need a phone nearby. The headphones function as a standalone MP3 player underwater. This setup ensures a seamless experience without relying on external connections.
For land-based activities, you use Bluetooth 6.0. The listing claims this chip provides instant pairing and stable sync. You connect the headphones to your mobile device or music source. The bone conduction design keeps your ears open. This allows you to hear ambient sounds while listening. The 28g frame and liquid silicone material provide a secure fit.

The battery supports 10 hours of continuous play. This duration covers long outdoor sessions without needing a recharge. You can choose between Orange or Grey colors.

Before You Buy The S18
You need a standard USB cable to charge the Rhyfell S18. The listing does not mention a specific charging dock or wireless charging capability. You must verify your device supports Bluetooth 6.0 for the instant pairing feature. Most modern smartphones and laptops support this, but older models may not connect properly. You should also check if your media player app allows direct transfer to MP3 mode. The 32GB storage holds over 8,000 songs, so you likely need a computer or compatible device for bulk transfers. Cleaning is simple. Rinse the liquid silicone frame with fresh water after saltwater or pool use. Dry it thoroughly before storage. This model sits alongside other bone conduction options. Unlike open-ear air conduction headphones, the S18 keeps your ears open for safety. It differs from standard wired swimming buds by offering wireless freedom and internal storage. You should compare battery life claims with other IP68 models. The 10-hour playtime is a key differentiator for long training sessions.
Check before you buy
- Confirm your device supports Bluetooth 6.0 for stable pairing.
- Verify your media app supports direct MP3 mode transfers.
