What reviewers said

Haylou T15

The Haylou T15 is an ultra-budget true wireless earbud that prioritizes battery life, offering up to 60 hours with its bulky charging case, which can also double as a power bank. Its sound leans toward treble, making it a decent match for rock or classical music, but fit and call quality are less impressive, and the overall experience feels average for the price.

  • Pro:Very long total battery life with the case
  • Pro:Charging case can recharge other devices
  • Pro:IPX5 water resistance
  • Con:Bulky charging case reduces portability
  • Con:Fit may be insecure for some users
  • Con:Call quality is below average

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
