Design Philosophy - “Harmonizing Sound with Aquatic Freedom”

Relxhome’s design philosophy behind the AS19, which can be summarized as “Harmonizing Sound with Aquatic Freedom,” reflects a deep understanding of the needs of water sports enthusiasts. The company recognizes that music can be a powerful motivator and enhancer of the athletic experience, but it should never come at the expense of safety or comfort. This philosophy is embodied in the AS19’s open-ear design, which allows for full situational awareness, and its lightweight, secure-fitting construction, which ensures the headphones remain comfortably in place during even the most vigorous activities. The integration of both Bluetooth and MP3 player modes caters to the diverse needs of users, offering them the flexibility to enjoy their audio content in any environment.

Bone Conduction: A Symphony Through Your Skull

Let’s delve into the fascinating science of bone conduction. Unlike traditional headphones that rely on air to transmit sound waves, bone conduction technology leverages the natural conductivity of your skeletal structure. The headphones generate tiny vibrations that travel through your cheekbones and skull, directly stimulating the cochlea – the inner ear’s hearing organ. This bypasses the eardrum altogether.

Think of it like this: your skull is not just a protective shell for your brain, it can also act as a unique kind of speaker. This is not a new concept, as many species in nature use similar mechanisms, for example, whales use their jawbones to collect and funnel sound vibrations in the ocean. This technology, for a long time, was mainly used in hearing aid, and now is making a huge impact on the sports headphone market.

Why is this beneficial? First, it leaves your ear canals open, allowing you to hear ambient sounds – crucial for safety, especially in open water. Second, it provides a surprisingly clear and consistent audio experience, even underwater. This method is particularly effective underwater because the density of water is closer to that of bone than air, making sound transmission more efficient.

IPX8 Waterproof: Conquering the Depths

The IPX8 rating is a testament to the AS19’s robust waterproofing. “IP” stands for “Ingress Protection,” a standardized rating system that classifies a device’s resistance to solids and liquids. The “X” in IPX8 means the device hasn’t been formally tested for solid particle protection (like dust), but the “8” signifies the highest level of protection against water immersion.

Specifically, an IPX8 rating, as implemented by Relxhome for the AS19, means the headphones can withstand continuous submersion in water up to 2 meters deep for up to 3 hours. This level of protection goes beyond mere splash resistance; it means you can confidently use these headphones during intense swimming sessions, surfing, or even snorkeling without fear of water damage. It is worth noting that each manufacturer defines their own parameters for IPX8, so checking the specific depth and time limits is always recommended.

How do they achieve this level of waterproofing? The AS19 likely employs a combination of watertight seals, specialized coatings on internal components, and a carefully designed housing to prevent water ingress.

MP3 Player Mode with 32GB Storage: Your Subaquatic Music Library

One of the most compelling features of the Relxhome AS19 is its built-in MP3 player and generous 32GB of storage. This transforms the headphones into a self-contained music library, capable of holding up to 8,000 songs. This is a game-changer for swimmers, as it eliminates the need to rely on a separate, potentially cumbersome, music player or a smartphone, which wouldn’t be practical or safe in the water.

Why is this important for underwater use? Bluetooth, while excellent for wireless connectivity on land, faces significant challenges underwater. Water greatly attenuates radio waves, drastically reducing the effective range and reliability of Bluetooth signals. With the built-in MP3 player, you can enjoy uninterrupted music playback regardless of your proximity to a transmitting device. You’re free to dive, turn, and explore the underwater world without signal dropouts. The AS19 supports a wide array of audio formats, including MP3, WAV, WMA, AAC, and even lossless FLAC, ensuring compatibility with your entire music collection. Transferring music is a breeze - simply connect the headphones to your computer via the included magnetic charging cable, and they’ll appear as a standard removable drive.

Bluetooth 5.3: Seamless Connectivity Above the Surface

While the MP3 player shines underwater, the Relxhome AS19 also boasts the latest Bluetooth 5.3 technology for seamless wireless connectivity on land. This newest iteration of Bluetooth offers significant improvements over its predecessors, including:

• Enhanced Data Transfer Rates: Enjoy faster pairing and quicker audio synchronization, minimizing any lag between your device and the headphones.
• Improved Power Efficiency: Bluetooth 5.3 consumes less power, contributing to the AS19’s impressive 10-hour battery life.
• Stronger, More Stable Connections: Experience fewer dropouts and interruptions, even in environments with high wireless interference.
• Extended Range: While the range can vary depending on the environment, Bluetooth 5.3 generally offers a wider operational range compared to older versions.

These enhancements ensure a smooth and enjoyable listening experience when you’re using the AS19 for activities like running, cycling, or simply relaxing at home. Remember, though, that Bluetooth’s effectiveness is severely limited underwater.

Open-Ear Design: Safety Through Sound Awareness

The open-ear design of the Relxhome AS19 is a crucial safety feature, especially for outdoor activities. By leaving your ear canals unobstructed, these headphones allow you to remain fully aware of your surroundings while enjoying your music.

Why is this so important? Whether you’re running on a busy street, cycling through traffic, or swimming in open water, the ability to hear approaching vehicles, warning signals, or other people is essential for your safety. Traditional in-ear or over-ear headphones can isolate you from these vital auditory cues, increasing the risk of accidents. The AS19’s open-ear design provides the best of both worlds: immersive audio without compromising your awareness of the environment.

Secure and Comfortable Fit: Designed for Motion

The Relxhome AS19 features a lightweight, over-ear design meticulously crafted to ensure a secure and comfortable fit during even the most strenuous activities. The headphones are engineered to stay firmly in place, whether you’re executing powerful swim strokes, sprinting on the track, or navigating a challenging bike trail.

How do they achieve this stability? The over-ear hooks provide a secure anchor point, while the flexible connecting band conforms to the shape of your head. The lightweight construction, at just 1.13 ounces, minimizes pressure and fatigue, allowing for extended wear without discomfort. While user “Homeschool Mom” found them generally comfortable, she did note a slight interference with glasses. This is a common challenge with over-ear designs, and individual experiences may vary depending on head shape and glasses style.

Extended Battery Life: Fueling Your Longest Sessions

With up to 10 hours of continuous playtime on a single charge, the Relxhome AS19 is built to last through your most ambitious workouts or a full day of aquatic adventures. This impressive battery life is a testament to the efficiency of both the bone conduction technology and the Bluetooth 5.3 chipset. As user FixedByNick reported, he could “use them all day and still at 60% when I put them back in charger.”

What contributes to this long battery life? Bone conduction, by its nature, tends to be more power-efficient than traditional headphone drivers. Additionally, advancements in battery technology and power management within the device itself play a crucial role. This extended playtime minimizes the need for frequent charging, allowing you to focus on your activities without worrying about your music cutting out.

Multifunction Button Control: Intuitive Operation

The AS19 features intuitive multifunction button controls that allow you to manage your music and calls without interrupting your workout. You can easily play/pause music, skip tracks, adjust volume, and answer calls with simple button presses. While the specific button combinations may take a little getting used to, they provide convenient control without the need to fumble with your phone or a separate remote. This is particularly helpful when your hands are wet or you’re engaged in physical activity.

Proprietary Magnetic Charging Cable: A Necessary Quirk

The AS19 uses a proprietary magnetic charging cable. While this ensures a secure and watertight connection for charging, it also means you’ll need to keep track of this specific cable.
