Is the AceZone A-Spire Wireless worth the upgrade from the Bose QuietComfort Ultra Headphones?
Verdict
Downgrade
The AceZone A-Spire Wireless actually scores 5.0 points below the Bose QuietComfort Ultra Headphones, so on aggregate review consensus this is a step backwards. The gains are concentrated in sound (7.0 to 8.5), battery (7.0 to 8.0) and calls (7.0 to 7.5). On paper: battery life 24 h to 35 h, bluetooth 5.3 to 5.4 and driver size 35 mm to 40 mm. Worth checking: weight goes 254 g to 289 g and multipoint pairing goes Yes to No. One caution: this steps down a line tier (QuietComfort Ultra Headphones to A-Spire Wireless), and base models usually trade away tier features - check the codec and ANC rows above before trusting the score gap alone. It is at least $80 cheaper, so the lower score comes with a saving. Only worth it if a specific feature above matters more to you than overall quality does.
