Design and Comfort

The PSIER SP05 Wireless Headphones have an over-ear open ear design, meaning there are no earbuds inserted into your ears. The headphones have a curved plastic housing that sits gently on the upper part of your ears, with soft silicone tips that provide a secure and comfortable fit.

Integrated within the housing are flexible titanium ear hooks that contour to your ear shape and keep the headphones firmly in place even during workouts. At just 5.9oz, the PSIER SP05 Wireless Headphones are lightweight enough for all-day wear.

The open ear design allows you to remain aware of ambient noises, which is ideal for outdoor workouts or use at the office. While audio leakage is noticeable at higher volumes, it shouldn’t be an issue at moderate levels.

True Open Ear Headphones

The PSIER SP05 headphones adopt a completely open design that allows you to wear them gently and firmly on the top of your ear. This design provides a more comfortable fit, making them suitable for extended periods of use.

40H Playtime & Digital Display

On a single full charge, the PSIER SP05 earbuds last up to 20 hours, and the charging case can charge the earbuds an additional time. This allows you to get a total of 40 hours of playtime from a fully charged case. Additionally, the smart LED Power Display in the case shows the remaining battery in real-time, which lets you know if the charging case or running headset needs to be charged or not.

Audio Quality

Featuring large 16.2mm speaker drivers, the PSIER SP05 Wireless Headphones delivers immersive and balanced sound with punchy bass and clear treble. While the open design prevents noise isolation, the audio output is tuned nicely for music, podcasts, calls and more. Volume could be louder at max level but is likely capped to protect hearing.

Be Aware of Surroundings

As the earbuds don’t go into your ear, the open ear design allows you to remain aware of your surroundings while listening to music. You can still hear approaching cars or other potential hazards while running or cycling outdoors, which enhances safety.

Sound Quality

With their 16.2mm vibrating diaphragm speaker drivers, a key highlight of the PSIER SP05 Wireless Headphones is sound quality. The headphones deliver surprisingly powerful, balanced stereo sound considering their open ear design.

The sound signature tends towards clean mids and highs with emphasized bass. While bass-heavy tracks can sound slightly boomy, the overall tuning provides an immersive listening experience. Maximum volume is lower than traditional headphones but should be adequate for most situations.

In terms of Bluetooth connectivity, the latest Bluetooth 5.3 ensures reliable pairing and minimal latency when watching videos. Call quality is decent, though volume may be insufficient in very noisy environments.

The PSIER SP05 True Wireless Headphones have an IPX5 waterproof rating. This means they are resistant to splashing water and sweat, making them suitable for workouts and active use.

IPX5 is tested by spraying water on the device from multiple angles for at least 3 minutes. The headphones can withstand low pressure water jets from any direction with no harmful effects.

This waterproof rating means you don’t have to worry about sweat damaging the earbuds during your workout or run. You can wash the PSIER SP05 True Wireless Headphones under a tap if they get dirty.

However, IPX5 does not make them fully waterproof. Do not submerge the PSIER SP05 Wireless Headphones in water or use them while swimming or showering. The earbuds and case should be protected from immersion.

For most exercise, fitness, and everyday use, the IPX5 rating provides sufficient water and sweat protection. Just avoid excessive water exposure and do not wear them while showering or swimming for best results.


The PSIER SP05 True Wireless Headphones has smart touch controls on each earbud, providing convenient access to playback, volume, calls, and voice assistants. The open ear design allows you to simultaneously listen and interact with your surroundings.
