Is the Technics EAH-AZ40 worth the upgrade from the Technics EAH-AZ60?
Verdict
Downgrade
The Technics EAH-AZ40 actually scores 14.0 points below the Technics EAH-AZ60, so on aggregate review consensus this is a step backwards. The gains are concentrated in battery (6.5 to 7.0). You do give up ground on sound (8.5 to 7.0) and calls (7.5 to 7.0). On paper: case weight 45 g to 30 g. Worth checking: codecs goes SBC, AAC, LDAC to SBC, AAC and driver size goes 8 mm to 6 mm. It is at least $75 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.
What actually changes
Sub-scores both products have, on the same 0-10 scale. Bars extend right for a gain, left for a loss.
