ANC: Sony's Edge
Sony's QN2e noise-cancelling chip in the WF-1000XM6 sets the standard for in-ear ANC. It handles mid-frequency noise (conversations, office HVAC, keyboard clatter) better than any competing earbud. The Technics EAH-AZ100's ANC is genuinely excellent — comparable to what the WF-1000XM5 offered — but on standardised tests it measures 2–4 dB less effective than the XM6, particularly in the 500 Hz–2 kHz speech range that matters most in offices.
Sound Quality
The Technics EAH-AZ100 is the audiophile choice. Its 10 mm driver produces a flat, studio-reference tuning with exceptional midrange clarity and a spacious stereo image. Acoustic instruments, vocals, and orchestral recordings sound particularly alive. The WF-1000XM6 has a warmer, more V-shaped signature that adds a hint of extra bass and treble sparkle — enjoyable for pop and electronic music, though slightly less precise by audiophile standards. Both support LDAC for hi-res wireless when paired with compatible Android phones.

Frequently Asked Questions
Frequently Asked Questions
Which earbuds have better ANC — WF-1000XM6 or EAH-AZ100?
The Sony WF-1000XM6 has a small but measurable edge in ANC effectiveness, particularly in mid-range frequencies like voices and office noise. The Technics EAH-AZ100's ANC is excellent and competitive with the previous-generation XM5, but Sony's QN2e chip is currently the benchmark.
Do both earbuds support LDAC for hi-res audio?
Yes. Both the WF-1000XM6 and EAH-AZ100 support LDAC at up to 990 kbps. The Technics additionally supports aptX HD, giving it a slight edge if your audio source supports aptX HD over LDAC.
Which is better for calls — Sony WF-1000XM6 or Technics EAH-AZ100?
The Sony WF-1000XM6 is better for calls. Its beamforming microphone array and AI noise processing consistently deliver clearer voice pickup in noisy environments. The Technics performs well for calls but Sony's call quality is among the best in any earbud.
Can these earbuds connect to three devices at once?
The Technics EAH-AZ100 supports three-device multipoint — a notable advantage over the WF-1000XM6 which connects to two devices simultaneously. If you switch between a laptop, phone, and tablet daily, the Technics wins this category outright.
How does battery life compare?
The EAH-AZ100 delivers around 10 hours per charge with ANC on, while the WF-1000XM6 offers around 8 hours. Both have cases that extend total listening to roughly 24–25 hours. The Technics wins battery life, but 8 hours is sufficient for most daily commutes.
Which sounds better for music listening?
This depends entirely on preference. The Technics EAH-AZ100 has a more neutral, audiophile tuning that reveals recording detail faithfully. The WF-1000XM6 has a warmer, slightly V-shaped tuning that many listeners find more engaging. Neither is objectively better — they serve different tastes.
Are the fit and comfort comparable?
Both use silicone ear tips in multiple sizes and sit securely in most ear shapes. The WF-1000XM6's shell is slightly smaller and lighter. The EAH-AZ100 uses a proprietary tri-hold fit that grips the outer ear for added stability during movement.
Which brand has better long-term software support?
Sony has a longer track record of firmware updates for WF series earbuds and the Sony Headphones Connect app is mature and feature-rich. Technics' app has improved significantly but Sony's ecosystem depth is greater, especially for iPhone users.
