Cleer Audio Arc II Standard

Manufacturer: Cleer

The Cleer Audio Arc II Standard sits in the open-ear segment of the wireless earbuds market, offering a true wireless design with wingtips for a secure fit and stereo sound through a 16.2 mm driver. With no wires or neckband to contend with, the earbuds weigh in at a light 28 g and carry an IPX5 rating, making them suitable for sweat-prone environments. In-ear detection enables automatic music pausing, and the included travel bag adds a layer of everyday practicality.

On the connectivity side, the Arc II Standard runs on Bluetooth 5.3 with aptX Adaptive and aptX Lossless codec support, alongside AAC, though it does not include LDAC, aptX HD, or NFC pairing. The maximum Bluetooth range is 10 m. The earbuds deliver up to 8 hours of battery life per charge, with the charging case extending that total to 27 hours; USB-C charging takes roughly 1.5 hours, and fast charging is supported. For calls and voice use, a four-microphone array with noise-canceling capability handles microphone duties, and the earbuds also support voice prompts, a mute function, and on-device control panel input.

Pros
  • Supports both aptX Adaptive and aptX Lossless codecs, enabling high-quality wireless audio transmission
  • Combined battery life of 35 hours between the earbuds and charging case provides extended use between full recharges
  • Fast charging support helps reduce downtime when the battery is running low
  • Four-microphone array with noise-canceling capability makes the earbuds well-suited for calls
  • In/on-ear detection automatically pauses playback when the earbuds are removed
  • IPX5 rating makes the earbuds resistant to sweat, suitable for physical activity
Cons
  • Open-ear design provides no passive noise reduction and no active noise cancellation, leaving the listener fully exposed to surrounding sounds
  • Maximum Bluetooth range of 10 m is relatively short for wireless earbuds
  • Wireless charging is not supported, requiring a wired connection every time the case needs recharging
  • No ambient sound mode is available for controlled awareness of the surrounding environment
  • NFC and fast pairing are both absent, making the initial connection process more manual
Who is this for?

The Arc II Standard is a good fit for users who want to stay aware of their surroundings while listening to music, making it well-suited for outdoor activities like running or cycling where situational awareness matters. The IPX5 sweat resistance and lightweight 28 g build make it practical for active, everyday wear, and the four-microphone noise-canceling array makes it a capable option for people who frequently take calls on the go. Those who prioritize high-fidelity wireless audio will also appreciate the inclusion of aptX Lossless and aptX Adaptive codec support, provided they use a compatible source device.

Who is this NOT for?

Users who require noise isolation or active noise cancellation — such as those working in loud offices, commuting on public transport, or needing to focus in noisy environments — will find the open-ear design fundamentally unsuitable for those scenarios. The 10 m Bluetooth range limit makes the earbuds a poor choice for situations where the source device needs to be left at a distance, such as in a gym or a larger workspace. Additionally, users who prioritize a fully wireless charging workflow will be inconvenienced by the absence of wireless charging support on the charging case.

Final Verdict

The Cleer Audio Arc II Standard is a well-defined open-ear wireless earbud option built around a clear set of priorities: audio codec quality, extended battery endurance, and comfortable all-day wearability. Its aptX Lossless and aptX Adaptive support, combined with a 35-hour total battery life and a capable four-microphone call setup, give it a solid foundation for users who value high-fidelity playback and practical everyday use. The open-ear design and sweat-resistant build make it genuinely suited to active lifestyles, though those same traits mean it will not satisfy users who need sound isolation or advanced environmental awareness features. On balance, the Arc II Standard is a focused product that delivers meaningfully in the areas it targets, making it a reasonable choice for listeners who want an open-ear experience without sacrificing wireless audio quality.
