#227 vivo TWS 4: $55 Wireless eBay
Pros: Budget wireless ANC earbuds at about $55 with a preference score of 78 across two measurements. Bass is full to 20 Hz, battery life is 11 hours with ANC off, and they support LDAC, aptX Adaptive and LC3.
Cons: A 5.2 dB peak near 7.7 kHz can add sibilance, and a 3.5 dB dip near 4.2 kHz softens vocal edges. They are sold mainly in China and India, and no IP rating is published.
Is the vivo TWS 4 right for you?
Buy it if
- you want the tuning most listeners prefer in blind tests out of the box (Harman score 78).
- you want sub-bass rumble that reaches down to 20 Hz.
- you want noise cancelling for commutes or flights.
Skip it if
- you want the best value: the higher-rated QCY HT05 MeloBuds ANC costs about $21 less.

Frequency Response
How the vivo TWS 4 measures across the audible range, against the Harman in-ear target that most listeners prefer in blind tests. Where the line sits above the target that range sounds louder (more bass, brighter treble), below it quieter. The curve is the average of 2 independent measurements, and both lines are shifted so their 500 Hz to 2 kHz average sits at 0 dB.
Measurement data: the average of 2 independent measurements from the squig.link databases of boizoff and regancipher. Thanks to each of them for publishing their work.
