What reviewers said

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

Redmi Buds 7S

The Redmi Buds 7S are budget-friendly half-in-ear earbuds that bring useful extras like multipoint, solid battery life, and clearer calls to the table. However, their adaptive noise cancelling feels nearly pointless at this level, and the sound quality doesn't live up to the potential of the hybrid driver setup. While they offer a decent feature set for the price, there are more compelling options in this crowded budget segment.

  • Pro:Good battery life with the case
  • Pro:Multipoint connection works well
  • Pro:Improved call clarity
  • Con:ANC is largely ineffective
  • Con:Sound quality is underwhelming
  • Con:No wireless charging
