Cleer Arc 4 Plus

Manufacturer: Cleer

The Cleer Arc 4 Plus are true wireless earbuds designed with an open-ear fit, making them a notable option for those who prefer situational awareness without in-canal isolation. They come with wingtips for a more secure hold, weigh just 21.6 g, and include a travel bag in the package. The earbuds support Dolby Atmos and spatial audio, giving content playback an added dimensional quality when the format is supported by the source material.

On the connectivity side, the Arc 4 Plus runs on Bluetooth 5.4 with aptX Adaptive and aptX Lossless codecs alongside AAC, covering a broad range of high-quality wireless audio transmission options. Multipoint connection supports up to two devices simultaneously, and USB Type-C handles charging with fast charging capability included. The earbuds themselves offer 9 hours of playback, extending to 25 hours with the charging case, and feature a quad-microphone setup with noise-canceling mic performance suited for calls and headset use.

Pros
  • Open-ear fit allows awareness of surrounding sounds during use
  • IPX7 water resistance rating offers solid protection against water exposure
  • Supports both aptX Lossless and aptX Adaptive codecs for high-quality wireless audio transmission
  • Dolby Atmos and spatial audio support add a dimensional quality to compatible content
  • Multipoint connection handles two devices simultaneously, reducing the need to manually switch sources
  • Comes with a travel bag and wingtips included in the box
Cons
  • No active noise cancellation or passive noise isolation, which limits use in loud environments
  • Open-ear design with no in-ear seal means audio can leak and external sounds are not blocked
  • Wireless charging is not supported, requiring a cable for every charge
  • No ambient sound mode available despite the open-ear form factor
  • Maximum Bluetooth range is limited to 10 m
  • Fast pairing and NFC pairing are not supported, making initial device connections more manual
Who is this for?

The Arc 4 Plus is well suited to users who prioritize situational awareness during outdoor or active use, as the open-ear design keeps surrounding sounds audible at all times. The IPX7 water resistance and secure wingtip fit make it a practical choice for workouts or commutes in variable weather. Those who frequently switch between devices will benefit from two-device multipoint connectivity, and users invested in high-fidelity wireless audio will appreciate the aptX Lossless and aptX Adaptive codec support alongside Dolby Atmos compatibility.

Who is this NOT for?

Users who need to block out environmental noise will find this product unsuitable, as it offers no active noise cancellation and no passive noise isolation — a direct consequence of the open-ear form factor. This also makes it a poor fit for focused listening in loud or busy environments such as open offices, public transit, or crowded spaces. Additionally, those who rely on wireless charging for convenience or expect features like ambient sound mode, in-ear detection, or NFC pairing will find these absent from the Arc 4 Plus.

Final Verdict

The Cleer Arc 4 Plus is a well-specified open-ear wireless earbud that makes a clear case for users who want to stay connected to their surroundings without sacrificing audio quality. Its aptX Lossless codec support combined with Dolby Atmos compatibility positions it firmly in the higher-quality end of the wireless audio spectrum, while the IPX7 rating and two-device multipoint connectivity add practical day-to-day reliability. Those expecting noise isolation or a fully sealed listening experience will need to look elsewhere, as the open-ear design is a deliberate trade-off rather than an oversight. For the right user — one who values awareness, high-fidelity wireless transmission, and a cable-free active lifestyle — the Arc 4 Plus delivers a coherent and well-rounded package.
