What reviewers said

Havit I91

The Havit I91 presents a tidy, professional-looking exterior, but its performance falls short of expectations. Muffled audio, awkward button controls, and subpar call quality make it a disappointing choice, even for budget-conscious listeners. Its only notable asset is its durable build and respectable battery life from the charging case.

  • Pro:Sturdy, workmanlike design
  • Pro:Compact and lightweight
  • Pro:Decent total battery life with case
  • Con:Muddy, unclear sound
  • Con:Poor call quality
  • Con:Clunky physical controls

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
