Eggel ComfortBuds S

Manufacturer: Eggel

The Eggel ComfortBuds S are true wireless earbuds designed for everyday in-ear use, combining a lightweight 6 g build with a practical feature set suited to commuters and general listeners alike. Each earbud comes with wingtips included for a more secure fit, and the set ships with a travel bag for portability. Active noise cancellation is built in, complemented by passive noise isolation, giving users two layers of sound management without relying on a neckband or any wired connection.

On the technical side, the ComfortBuds S use a 6 mm driver unit covering a 20 Hz to 20,000 Hz frequency range and are backed by four microphones with noise-canceling capability, making them usable as a headset with a mute function. Bluetooth 5.2 handles wireless connectivity up to 10 m with an audio latency of 50 ms. Battery life reaches 7 hours per charge, or 5 hours with ANC active, while the 250 mAh charging case extends total playback to 21 hours; charging is handled via USB Type-C and fast charging is supported, with a full charge taking around 1.5 hours.

Pros
  • Both active noise cancellation and passive noise isolation are included, giving two layers of sound management
  • The four-microphone setup with noise-canceling capability makes hands-free calls more reliable in noisy environments
  • Fast charging support reduces downtime, and the charging case extends total battery life to 21 hours
  • At just 6 g per earbud with wingtips included, the fit is lightweight and designed to stay secure during use
  • A travel bag is included in the box, making transport more practical without needing extra accessories
  • USB Type-C charging keeps the connection type modern and widely compatible
Cons
  • No wireless charging support for the case, requiring a cable every time
  • Advanced audio codecs such as LDAC, aptX, and AAC are all absent, limiting audio transmission quality options
  • Bluetooth range is capped at 10 m, which may feel restrictive in larger spaces
  • There is no in/on-ear detection, so music will not pause automatically when an earbud is removed
  • The find device feature is not available, making it harder to locate misplaced earbuds
Who is this for?

These earbuds are a practical choice for daily commuters and office workers who regularly deal with background noise, thanks to the combination of active noise cancellation and passive noise isolation. The four-microphone system with noise-canceling capability also makes them well-suited to people who frequently take calls or participate in voice meetings throughout the day. At just 6 g per earbud with wingtips for added stability, they work well for users who need a lightweight, secure-fitting true wireless option for extended wear, and the 21-hour total battery life with the case means they can comfortably handle full-day use without frequent recharging.

Who is this NOT for?

Users who prioritize high-fidelity audio transmission will find these earbuds limiting, as there is no support for advanced codecs such as LDAC, aptX, or AAC, which restricts the quality ceiling for wireless audio. The 10 m Bluetooth range and lack of in/on-ear detection make them a weaker fit for users who move frequently between rooms or expect automatic playback control when removing an earbud. Those looking for a fully cable-free experience at the charging stage will also be disappointed, as wireless case charging is not supported.

Final Verdict

The Eggel ComfortBuds S position themselves as a practical everyday wireless earbud for users who value noise management and all-day wearability.

Where they fall short is in audio codec support and smart features, which keeps them out of reach for audiophiles or users expecting a more seamless hands-free experience. For those whose main priorities are comfort, reliable noise reduction, and solid call performance, the Eggel ComfortBuds S deliver a focused and functional package.
