Introducing the Technics EAH-AZ40M2<\/strong>!<\/p>\n\n\n\n

This past summer, we reviewed the higher-end EAH-AZ80<\/a> and were impressed by its blend of technical features and refined soundstage. With the arrival of the EAH-AZ40M2<\/strong>, we were keen to investigate the compromises made to achieve a lower price point. Is the cost reduction justified, and does the EAH-AZ80 offer sufficient value to warrant the price difference?<\/p>\n\n\n\n

While distinctions exist between these two models, the EAH-AZ40M2 is more than a mere budget alternative. Initial impressions indicate that it shares many capabilities with its flagship counterpart, although some design choices by Technics are less than ideal.<\/p>\n\n\n\n

The size difference matters a lot<\/strong><\/h2>\n\n\n\n

The Technics EAH-AZ40M2 boasts a more compact design across the board. It features a lighter build, smaller drivers, reduced charging capacity, smaller batteries, and omits wireless charging. While these aspects may initially seem like drawbacks, a closer examination reveals certain advantages. Similar to our comparison between the Roborock S8<\/a><\/strong> and the Roborock S8 Pro Ultra<\/a><\/strong> robot vacuum cleaners, additional features often necessitate increased space, and sometimes a more streamlined design is preferable.<\/p>\n\n\n\n

The earbud itself presents a distinct shape and a lighter weight (five grams versus seven). For users with sensitive ears, this weight reduction may be more crucial than extended battery life. The lower profile of the earbud also makes it more suitable for activities like cycling or use in windy conditions. The absence of wireless charging and the reduced case capacity (18 hours compared to 24) contribute to a smaller and lighter case, improving portability.<\/p>\n\n\n\n

However, the smaller dimensions inevitably lead to smaller drivers (6 mm compared to 10 mm), which impacts the soundstage, dynamics, and overall listening experience. During our standard test playlist, the EAH-AZ40M2 exhibited a somewhat subdued and less immersive sound profile. Critical listeners may find themselves increasing the bass and volume levels compared to the EAH-AZ80, potentially impacting battery life.<\/p>\n\n\n\n

To be clear, the sound quality remains commendable, but it lacks the vibrancy of the EAH-AZ80. While the audio is precise and accurate, it doesn’t achieve the same level of acoustic depth as its higher-end counterpart.<\/p>\n\n\n\n

Features Retained Despite the Lower Price<\/strong><\/h2>\n\n\n\n

The Technics Audio Connect app received a significant upgrade with the launch of the EAH-AZ80 and the EAH-AZ60M2 this summer. The EAH-AZ40M2 utilizes the same application, granting access to a wide array of features. This includes three-point connectivity, allowing users to customize the names of their connected devices \u2013 a feature currently exclusive to Technics. Users also gain comprehensive control over button assignments (single, double, triple, and long presses), ambient sound modes, and a range of sound profiles.<\/p>\n\n\n\n

However, some features are partially implemented on the EAH-AZ40M2, which is regrettable. The noise cancellation is Feed-Forward rather than Dual-Hybrid. While still effective, the option to customize the noise cancellation level is absent. With the Sony WH-1000XM4<\/a><\/strong>, for example, users can find relief by reducing or disabling noise cancellation. On a positive note, like the EAH-AZ80, the EAH-AZ40M2 maintains its soundstage integrity even with noise cancellation enabled.<\/p>\n\n\n\n
