Is the Cambridge Audio Melomania A100 worth the upgrade from the OnePlus Buds Z?
Verdict
Clear upgrade
Going from the OnePlus Buds Z to the Cambridge Audio Melomania A100 buys you 31.4 points of HearWiki score - a clear step up that reviewers agree on rather than a marketing refresh. The gains are concentrated in battery (4.3 to 8.5), calls (5.0 to 8.0) and sound (6.1 to 9.0). On paper: battery life 5 h to 11 h, active noise cancelling and codecs SBC, AAC to SBC, AAC, aptX Adaptive, aptX Lossless, LDAC. Worth checking: weight goes 4.3 g to 9.4 g. That costs $49 more, or about $2 per point of score - reasonable value for the jump. If your current pair is worn out or the gains line up with how you listen, this one is worth the money.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
