Reviews last updated: November 2026 · How we calculate this

What customers like about Sync By 50 On Ear

  • Comfortable fit featuring 'OvalFit' memory foam ear cushions that reduce ear fatigue
  • Stylish and sleek design with a durable rubberized finish
  • Easy-to-operate on-ear controls for volume and track navigation
  • Impressive battery life, typically lasting between 10 to 17 hours on a single charge
  • Versatile connectivity with both wireless (Bluetooth/Kleer) and a detachable 3.5mm wired cable
  • Solid construction quality that can withstand regular gym use and some sweat (IPX4 rated)

What customers don't like about Sync By 50 On Ear

  • Unbalanced sound signature with overwhelming bass that can lead to a 'muddy' or 'unrefined' audio experience
  • High price point relative to the audio performance when compared to competitors
  • Wireless connectivity often requires a clunky, easy-to-lose dongle (on older Kleer models)
  • Audio distortion can occur at high volume levels, especially when using the bass boost feature
  • Passive noise isolation is weak and does not effectively block out low-frequency ambient noise
  • On-ear controls may have limited functionality depending on the connected device or mode (wired vs. wireless)

Verdict

The SMS Audio Sync by 50 On-Ear headphones feature custom-tuned 40mm drivers designed to deliver a balanced soundstage with a powerful, punchy bass boost and support for the aptX codec over Bluetooth 4.0. Key characteristics include a foldable, lightweight design with soft leather memory foam ear pads for comfort, an IPX4 sweat-resistant rating for athletic use, and a battery life offering up to 10–12 hours of playback. Its main pros are the exceptionally comfortable fit, clear mid-range and highs, and convenient on-ear controls for volume and track navigation. However, cons include a high price point at launch, a lack of active noise cancellation (ANC), and occasional audio distortion when pushed to maximum volume.
