What we like about Boult Audio Sterling Pro

  • Premium metallic frame and 'classy' aesthetic with gunmetal and silver strap options
  • Vibrant 1.43-inch AMOLED HD screen with Always-on Display (AOD) and 800 nits brightness
  • Functional rotating crown for easy navigation
  • Clear Bluetooth calling supported by a built-in speaker and microphone
  • Extensive customisation with over 250 cloud-based watch faces
  • IP68 water and dust resistance rating for outdoor durability

What we don't like about Boult Audio Sterling Pro

  • Mixed battery performance; while some report 7-day life, others find it requires daily charging
  • Inaccurate health monitoring readings, specifically for blood pressure
  • Limited support for third-party applications
  • Software interface can feel cluttered and may have a learning curve for new users
  • Higher price point compared to entry-level fitness trackers in the same segment

Verdict

The Boult Audio Sterling Pro is a circular smartwatch featuring a 1.43-inch AMOLED HD display with a 466 x 466 pixel resolution and 461 ppi density. It offers Bluetooth 5.3 calling with a built-in speaker and microphone, a functional working crown, and a premium stainless steel strap. Key health and activity features include 100+ sports modes, SpO2 monitoring, heart rate tracking, blood pressure monitoring, and IP68 water resistance. Its main pros include a vibrant Always-On Display, a durable zinc alloy build, and up to 7 days of battery life. However, it lacks GPS and NFC, has limited third-party app support, and some users find the companion app interface cluttered.
