What reviewers said

Bluedio Fi

The Bluedio Fi offers a feature-rich budget package with Bluetooth 5.0, aptX support, USB-C, touch controls, and an auto play/pause sensor, plus an app for extra control. However, its core performance in sound quality and wireless stability leaves much to be desired, making it a mixed pick for thrifty shoppers. It does handle calls decently thanks to CVC noise filtering, but overall it struggles to stand out against similarly priced rivals.

  • Pro:Supports aptX for better Android audio
  • Pro:Touch controls with auto play/pause sensor
  • Pro:USB-C charging and IPX5 sweat resistance
  • Con:Sound quality is underwhelming
  • Con:Connectivity can be unreliable
  • Con:Battery life is modest at 5 hours per charge

Nothing CMF Buds 2

The Nothing CMF Buds 2 are an exceptional budget true-wireless option, packing a surprisingly rich feature set for their low price. They deliver engaging sound, robust battery life, and effective hybrid ANC, making them a top-value pick for most listeners.

  • Pro:Excellent value for the price
  • Pro:Strong battery life with ANC off
  • Pro:Effective hybrid active noise cancellation
  • Con:Call performance weak in noisy settings
  • Con:ANC and gaming latency not class-leading
  • Con:No wireless charging support
