Technics EAH-AZ80-K
Score: 83/100
Beyerdynamic Amiron 300
Score: 70/100Rankings
The Technics EAH-AZ80-K provides high-resolution audio, effective dual-hybrid ANC, and a rich feature set including multipoint pairing and wireless charging. Its battery life and touch-control sensitivity are the main drawbacks for power users.
The Amiron 300 delivers audiophile-grade sound and LDAC high-resolution support in a compact, IP54-rated true-wireless design. Battery life is solid, and the app offers deep EQ customization, but ANC falls short of market leaders and touch controls feel finicky.

Professional reviewers praised the AZ80 for its rich sound, effective hybrid ANC, and excellent call quality, earning high marks from CNET and HIFI Trends.
Everyday users highlight the superb audio fidelity, comfortable fit, and long case battery life, while repeatedly noting the reduced LDAC runtime, touch-control sensitivity, and limited tip selection on the newer model.
“The sound is rich and detailed, perfect for my daily commute.”
“Touch controls are too sensitive; I keep pausing my music unintentionally.”
“Battery lasts all day with ANC off, but drops fast with LDAC.”
Professional reviewers commend the Amiron 300 for its detailed sound and LDAC support, but note that its ANC lags behind top competitors and the touch controls lack refinement.
Everyday users love the sound detail, fit, and EQ app, yet many report ANC artifacts, case ejection issues, unstable multipoint pairing, and muffled microphone quality in noisy settings.
