Technics EAH-AZ40M2 True Wireless Noise Cancelling Earbuds at Vinyl Sound Toronto Canada

The Technics EAH-AZ40M2 are ultra-compact true wireless noise cancelling earbuds from Technics (Osaka, Japan), available at Vinyl Sound in Toronto, Canada. Designed to fit even smaller ears, the AZ40M2 packs Technics' signature audio DNA into the most compact form in the lineup — a newly developed 6 mm driver with integrated acoustic control chamber and harmoniser, feedforward Active Noise Cancelling, multipoint connection to three devices simultaneously, Beamforming Technology with four MEMS microphones for call clarity, and up to 5.5 hours of ANC-on playback with 18 total hours including the case. With IPX4 water resistance and plastic-free packaging, the AZ40M2 is the entry point into Technics true wireless performance for listeners who prioritise a compact, lightweight fit above all else.

6 mm Driver with Acoustic Control Chamber and Harmoniser

Despite its ultra-compact dimensions, the AZ40M2 carries the same acoustic engineering philosophy as the larger AZ60M2 and AZ80. The newly developed 6 mm driver integrates an acoustic control chamber — a tuned air volume that shapes the bass and midrange response — and a harmoniser that reduces harmonic distortion and expands the perceived soundstage. These are the same two elements that give the larger Technics earbuds their characteristic natural, direct sound with powerful bass. Achieving them in a 6 mm driver compact enough for smaller ears required a purpose-built integrated chamber design rather than the separate chamber construction used in the larger models. Frequency response extends to 40 kHz via LDAC at 96 kHz / 990 kbps, confirming genuine high-resolution wireless capability.

Active Noise Cancellation and Ambient Sound Control

The AZ40M2 uses a feedforward ANC configuration, with an outward-facing microphone on each earbud that captures ambient sound and applies digital processing to cancel it before it reaches the ear. Natural Ambient Mode passes surrounding sound through comprehensively for a transparent, near-open-ear experience when awareness is needed. Attention Mode selectively reduces unwanted background noise while prioritising speech frequencies, making it easier to follow conversations, announcements, or instructions without removing the earbuds.

Frequently Asked Questions

What are the Technics EAH-AZ40M2 earbuds?

The Technics EAH-AZ40M2 are ultra-compact true wireless noise cancelling earbuds with a 6 mm driver featuring an integrated acoustic control chamber and harmoniser, feedforward ANC, three-device multipoint connection, Beamforming Technology with four MEMS microphones, 5.5 hours ANC-on playback with 18 total hours from the case, LDAC support, and IPX4 water resistance. They are Technics' most compact true wireless earbuds, designed to fit smaller ears.

What is the difference between the AZ40M2 and the AZ60M2?

The AZ60M2 uses a larger 8 mm driver and Dual Hybrid ANC combining feedforward and feedback microphones for stronger noise cancellation, compared to the AZ40M2's feedforward-only system. The AZ60M2 also adds Qi wireless charging, eight microphones with JustMyVoice technology for superior call performance, wear detection, and seven eartip sizes. The AZ40M2 is the better choice for listeners who prioritise a smaller, lighter form factor; the AZ60M2 steps up in every performance category.

Does the EAH-AZ40M2 support LDAC?

Yes. The AZ40M2 supports LDAC at 96 kHz / 990 kbps, delivering high-resolution wireless audio with a frequency response extending to 40 kHz. Note that LDAC availability depends on the connected device supporting the codec.

Can I connect the AZ40M2 to multiple devices at once?

Yes. The AZ40M2 supports simultaneous multipoint connection to three Bluetooth devices such as a laptop, tablet, and smartphone. It switches between them seamlessly without manual re-pairing when the active audio source changes.

Does the AZ40M2 support wireless charging?

No. The AZ40M2 charges via USB-A to USB-C cable only. Qi wireless charging is available on the AZ60M2 and AZ80 if wireless charging is a priority.

Are the AZ40M2 suitable for small ears?

Yes. The AZ40M2 is Technics' most compact true wireless earbud, specifically designed to fit smaller ears. The redesigned flatter earbud body expands contact with the ear canal for a more stable fit, and four eartip sizes (XS, S, M, L) allow a precise acoustic seal across a wide range of ear shapes and sizes.
