If you want true wireless freedom with studio-grade audio for your daily commute and intense workouts, choose SoundPEATS Air5; if you need a dedicated, high-fidelity music player that doubles as a swimming companion with massive battery life and lossless playback, choose AGXOV HiFi MP3.
• SoundPEATS Air5: Delivers reference-grade Hi-Res sound with LDAC and adaptive noise cancellation in a sleek, ergonomic in-ear design; the trade-off is its lack of native MP3 storage and reliance on a paired device.
• AGXOV HiFi MP3: Offers standalone high-resolution audio with 50 hours of playtime and robust build quality for deep bass lovers; the trade-off is the absence of active noise cancellation and the requirement to carry a separate unit rather than just earbuds.
• Who picks which: Choose the Air5 if you prioritize seamless wireless connectivity and immersive isolation for gym sessions or travel; pick the AGXOV if you demand pure, unadulterated audio fidelity and long endurance for swimming without worrying about phone pairing.
The SoundPEATS Air5 Pro is engineered for the listener who refuses to compromise on audio quality while demanding the convenience of a completely wireless experience. At the heart of this design is a custom 10mm driver featuring a multi-layer PU+PEEK diaphragm and an N50 dual magnet system. This combination creates a dynamic range that handles everything from the delicate nuances of classical compositions to the heavy impact of electronic beats with minimal distortion. The inclusion of both LDAC and aptX Lossless codecs means the data transmitted over Bluetooth is significantly higher than standard connections, preserving the full fidelity of high-resolution files right down to the ear.
What sets this model apart for active users is the physical engineering behind the sound isolation. The fully isolated rear chamber acts as a physical barrier against external interference, working in tandem with Adaptive Hybrid Active Noise Cancelling to create a silent auditory canvas. This is critical for anyone trying to focus during a busy commute or block out distractions in a loud gym environment. With Bluetooth 5.4 LE Audio support, the connection remains stable even when moving quickly, ensuring that the expansive soundstage remains intact without dropouts.
However, this product is not designed for everyone. It is strictly a pair of earbuds; it does not store music internally. You must pair it with a smartphone or another source device to function. If you are looking for a standalone unit that can hold your entire library without needing a phone nearby, this is not the solution. Additionally, while it carries an IPX5 waterproof rating suitable for sweat and rain, it is primarily built for terrestrial sports like running or cycling rather than submersion. It is ideal for those who want a premium listening experience that fits securely in the ear and offers up to 37 hours of total playtime with its charging case, but it requires a connected device to operate.

The AGXOV HiFi MP3 Player serves a different purpose entirely, catering to audiophiles who want a dedicated, portable station for their music collection. This device is built around a high-grade zinc alloy chassis that feels substantial and durable in the hand, housing a 2.8-inch HD touchscreen and a retro-style mechanical knob for precise volume control. The core strength here lies in its processing power; equipped with an ES9018K2M DAC, it achieves a signal-to-noise ratio of 127dB and less than 0.001% THD+N. This level of engineering ensures that the background noise is virtually eliminated, delivering pristine audio fidelity that reveals details often lost in lower-quality players.
For swimmers and outdoor enthusiasts, the standout feature is the massive 50-hour battery life. Unlike many wireless earbuds that require frequent charging, this player can sustain extended listening sessions across days of use. It supports native DSD256 playback and up to 24-bit/192kHz audio, making it capable of handling a vast array of formats including FLAC, APE, WAV, and DSF. The 64GB internal memory, expandable via Micro SD up to 256GB, allows you to carry a library of thousands of high-resolution tracks without relying on cloud streaming or a smartphone. While it functions as a Bluetooth transmitter to connect to headphones, it operates independently as a music source, removing the need to keep your phone in your pocket.
This device is perfect for the user who prioritizes audio purity and longevity over the convenience of a single wearable unit. It is particularly well-suited for those who swim, as the robust construction and long battery life make it a reliable companion for poolside or open-water sessions where recharging isn't an option. However, potential buyers should note that it lacks active noise cancellation. The silence you get comes from passive isolation provided by your headphones, not from the player itself actively cancelling out environmental sounds. It is also a larger form factor than earbuds, requiring you to carry a separate device to your ears. If you want the absolute best deep bass wireless headset performance without compression artifacts, this is the hardware choice, but it demands you manage two items: the player and your listening device.
• Best for swimming → AGXOV HiFi MP3, thanks to its independent operation, massive battery, and durable build that doesn't rely on a phone connection.
• Best for wireless convenience → SoundPEATS Air5, offering true TWS functionality with Bluetooth 5.4 for instant pairing and zero cable clutter.
• Best for battery endurance → AGXOV HiFi MP3, delivering 50 hours of continuous playback compared to the Air5's 37-hour total (including case).

• Best for audio format support → AGXOV HiFi MP3, natively decoding DSD256 and supporting 24-bit/192kHz files directly without needing a specific app or codec from a phone.
• Best for portability → SoundPEATS Air5, as they fit entirely inside a small case, whereas the AGXOV is a standalone brick-like device.
• Best for customization → SoundPEATS Air5, allowing EQ adjustments and feature tweaks via the PeatsAudio App on your smartphone.
• Best value for audio purists → AGXOV HiFi MP3, providing a professional-grade DAC and lossless playback engine at a price point that undercuts standalone hi-fi equipment.
In my opinion, if you are specifically looking for wireless earbuds for swimming or a dedicated audio setup for underwater use, the AGXOV HiFi MP3 is the superior choice. Its 50-hour battery life and ability to operate completely independently mean you never have to worry about your phone dying mid-swim or losing connection due to water interference. The ES9018K2M DAC ensures that every note hits with the clarity you expect from high-end gear. Conversely, if your primary goal is a daily driver for the gym or commute where noise cancellation and seamless wireless switching matter more than raw file decoding, the SoundPEATS Air5 is the better tool. I would personally buy the AGXOV for swimming because the independence and battery life are non-negotiable for that activity, while I would reach for the SoundPEATS Air5 for everything else where I need to block out the world and enjoy lossless sound wirelessly.
The SoundPEATS Air5 has an IPX5 rating, which protects against sweat and rain, but it is not designed for submersion. The AGXOV HiFi MP3 is a standalone player that works with compatible waterproof headphones, making it a viable setup for swimming as long as the headphones themselves are rated for water immersion.
Both utilize high-quality drivers, but the AGXOV HiFi MP3 pairs with external headphones and features a high-performance DAC that can drive deeper, cleaner bass with less distortion. The SoundPEATS Air5 uses a custom 10mm driver with a dual magnet system to deliver robust bass directly, but it relies on the headphone fit for low-frequency performance.
Yes, you need a smartphone to set up and control the SoundPEATS Air5, as it stores no music internally. The AGXOV HiFi MP3 does not require a phone to play music once your library is loaded onto its 64GB storage, though a phone is needed initially to transfer files.
The SoundPEATS Air5 includes Adaptive Hybrid Active Noise Cancellation to block out external sounds. The AGXOV HiFi MP3 does not have active noise cancellation; it provides high-fidelity audio that relies on the passive isolation of your headphones to reduce background noise.
