Third-party reviews

Based on ratings from across the web.
Reviews last updated: November 2026 · How we calculate this

What customers like about SMS Audio Biosport

  • No battery required as they draw power through the 3.5mm jack
  • Accurate heart-rate monitoring when a proper fit is achieved
  • IPX4 sweat and water resistance suitable for workouts
  • Secure fit for many users due to the stay-fit wing design
  • Tangle-free flat cable for easier storage
  • Includes multiple ear gel sizes and a protective carrying case

What customers don't like about SMS Audio Biosport

  • Limited app compatibility; RunKeeper support has been inconsistent or discontinued
  • Lacks on-device volume controls
  • Audio quality is often described as underwhelming or lacking bass for the price
  • Bulky in-line heart rate monitor housing can be heavy and pull on the ears
  • Fit can be difficult to get right, which directly impacts heart-rate tracking accuracy
  • 3.5mm jack design may not fit through some smartphone cases

Verdict

The SMS Audio BioSport is a specialized in-ear biometric headphone developed in partnership with Intel, featuring a built-in optical heart rate monitor that tracks fitness data without a chest strap. These earbuds utilize 12mm drivers to deliver 'Studio Mastered Sound' and are IPX4-rated for sweat and water resistance, making them ideal for high-intensity workouts. A key advantage is their battery-free design; they draw necessary power directly from a smartphone via a gold-plated 3.5mm jack. While they offer accurate biometric tracking and a secure, comfortable fit with 'stay-fit' wings, notable drawbacks include limited app compatibility, lack of on-device volume controls, and sound quality that some users find lacking in deep bass.
