What reviewers said
Bluedio T-Elf 2
The Bluedio T-Elf 2 is a very affordable true wireless earbud with Bluetooth 5.0, touch controls, and IPX4 splash resistance. Its sound leans toward a light, bass-shy profile, and while the fit may suit smaller ears, connection behavior and overly sensitive controls hold it back. It's a budget pick for undemanding listeners rather than a standout performer.
- Pro:Very low price
- Pro:Compact fit for smaller ears
- Pro:IPX4 splash resistance
- Con:Weak, bass-light sound
- Con:Annoying auto-connection behavior
- Con:Overly sensitive touch 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
