What Buyers Say
Technics EAH-AZ100-N
92 out of 100 low confidence 8 reviews
The Technics EAH-AZ100 earbuds receive overwhelmingly positive feedback for their exceptional sound quality, particularly with LDAC and Dolby Atmos. Users highlight the surprisingly effective AI-powered call noise cancellation, which blocks out background noise like screaming children or car washes. Comfort and customization via the app are also praised, though some note the ANC is slightly weaker than the previous AZ80 model.
