Baseus AirGo AS01

Name: Baseus AirGo AS01
Brand: Baseus
SKU: 9550

Manufacturer: Baseus

The Baseus AirGo AS01 are true wireless earbuds with an open-ear fit, designed for users who want to stay aware of their surroundings while listening. They weigh just 9.2 g, come with wingtips for a more secure fit, and include a travel bag in the box. Four built-in microphones with noise cancellation make them functional as a headset for calls, and a mute function adds practical control during conversations.

Connectivity runs on Bluetooth 5.3 with AAC codec support and a maximum range of 10 m, while USB Type-C handles wired charging. The earbuds deliver up to 5 hours of playback per charge, with the charging case extending total use to 25 hours; fast charging is supported, and a full charge takes around 1 hour. Audio is handled by 10 mm drivers covering a 20 Hz to 20,000 Hz frequency range, though there is no active or passive noise isolation, no wireless charging, and no high-resolution audio codec support such as LDAC or aptX.

Pros

Four-microphone array with noise cancellation supports clearer voice calls by reducing background noise
Total battery life reaches 25 hours when combining the earbuds and charging case, offering extended use between full recharges
Fast charging is supported, reducing downtime when the battery runs low
A travel bag is included in the box, providing a ready-made storage and carrying solution
Open-ear design with wingtips allows ambient awareness while keeping the earbuds secure during wear
Mute function and headset capability make them practically useful for calls and voice communication

Cons

No water resistance of any kind, making them unsuitable for use in rain or during sweaty activities
No active or passive noise isolation, which limits their usefulness in loud environments where focused listening is needed
Only AAC codec is supported, with no LDAC, aptX, or any other high-resolution audio codec available
No fast pairing or NFC pairing, meaning the initial connection process requires manual Bluetooth setup
No in-ear detection, so music will not automatically pause when the earbuds are removed
No find device feature, offering no way to locate the earbuds if misplaced

Who is this for?

These earbuds are well matched to users who prefer an open-ear listening experience that keeps them aware of their surroundings, making them a practical choice for office environments, light commutes, or casual everyday use. The 4-microphone noise-canceling setup and headset functionality suit people who take frequent calls and need reliable voice pickup without carrying a dedicated headset. With 25 hours of total battery life and fast charging support, they also work well for users who need extended daily use without frequent interruptions to recharge.

Who is this NOT for?

Users looking for noise isolation or active noise cancellation will find these earbuds unsuitable, as neither feature is present — making them a poor fit for loud commutes, flights, or any environment where blocking out external sound matters. The complete absence of water resistance rules them out for workouts, outdoor sports, or any situation involving sweat or rain exposure. Listeners who prioritize audio quality through high-resolution codecs will also be disappointed, as only AAC is supported and there is no LDAC, aptX, or equivalent option available.

Final Verdict

The Baseus AirGo AS01 are open-ear true wireless earbuds that settle into a clear niche: casual everyday use where situational awareness, call quality, and all-day battery endurance matter more than acoustic isolation or high-resolution audio. The 4-microphone noise-canceling array and 25-hour combined battery life are the standout functional strengths, and the inclusion of fast charging and a travel bag adds everyday practicality. That said, the lack of water resistance and any form of noise isolation means the use case remains fairly narrow. For users whose primary needs align with hands-free calling, open-ear comfort, and reliable wireless connectivity, the AirGo AS01 delivers a focused and coherent package — but those seeking versatility across varied environments or audiophile-grade codec support will need to look elsewhere.
