What reviewers said
Cowin KY02
The Cowin KY02 is a budget-friendly true wireless option that leans into a mid-focused sound signature, making it a reasonable pick for those who prioritize vocals or need a sporty, sweat-resistant companion. Its practical strengths include a comfortable fit, solid battery life, and quick Bluetooth pairing, though the touch controls can be finicky and the lack of ANC is noticeable. At around $40, it's a decent everyday performer for casual listening and workouts, but not a standout for critical audio quality.
- Pro:Comfortable and secure fit for workouts
- Pro:Strong battery life with the charging case
- Pro:Quick and stable Bluetooth 5.0 pairing
- Con:Touch controls are awkward and frustrating to use
- Con:No active noise cancellation despite marketing hints
- Con:Mid-centric tuning won't satisfy bass-heavy or treble-sensitive listeners
Soundcore Space A40
The Soundcore Space A40 earbuds deliver a well-rounded budget experience, combining effective adaptive noise cancellation, balanced audio, and long battery life with multipoint connectivity. They offer strong value at around $100, with a comfortable fit and support for LDAC, though a few ergonomic and performance quirks keep them from being flawless.
- Pro:Effective adaptive ANC for the price
- Pro:Balanced, pleasant sound with LDAC support
- Pro:Long battery life with wireless charging case
- Con:Microphone quality is mediocre
- Con:Touch controls can be inconsistent
- Con:Case hinge feels less sturdy
