The sound – how good do the Technics EAH-AZ70W sound?

The premium headphones from Technics do a very good job in terms of sound. They represent the musical content very neutrally and true to the original. This was noticeable, for example, with our test song Hurt by Johnny Cash. The late-onset and very dominant piano is not overly emphasized by the Technics and fits nicely into the overall picture.

The Weeknd’s strong bass song Pray For Me sounds just as good with the Technics. The headphones only let the dominant bass come to the fore when it is supposed to be dominant. With some other headphones, a constant bass thump can be heard here. Technics confidently avoids such a thing.

The third test song is Don’t Stop Me Now by Queen. Again, this song wins, especially when the playback device can represent the dynamics of the individual instruments well. Here the Technics EAH-AZ70W convince across the board in the test. And the earbuds don’t tend to oversteer.

The same applies to podcasts and audiobooks, which sound consistently pleasant. In terms of sound, the True Wireless headphones from Technics, with their very neutral, natural-sounding reproduction, are among the best models on the market.

Practice – How good are the battery life and fit of the in-ears?

Since the headphones are True Wireless, i.e., completely wireless, they need their battery. This maintains the Technics EAH AZ70W when switched on Active Noise Canceling up to 6.5 hours. Compared to other true wireless headphones, this is a really good value! So you can easily get through half a day on one battery charge.

The charging case enables the headphones to be fully charged two more times so that the headphones offer up to 19.5 hours of listening pleasure on the go without using electricity. Most competitors offer three additional full battery charges with the charging case and a slightly longer listening time. The construction of the charging case is not overly large but a bit clunky, so it is not necessarily suitable for tight trouser pockets.

Anyone who organizes long music sessions or listens to audiobooks for hours at a time certainly values ​​a comfortable fit. Technics offer these. The headphones are classic in-ears and are built so that they do not press in the ear even after several hours.

The microphone technology of the Technics is also very good. The same technology that ANC headphones use to filter out continuous noises during phone calls. Of course, this does not work 100 percent but even surrounded by car noise. Nevertheless, you can still have understandable conversations with the Technics. If you use the phone continuously, the headphones’ battery life is reduced to about 4.5 hours. The headphones are protected against splash water under the IPX4 standard and can be used carefree during sports.

Operation – setting options and operation of the Technics EAH-AZ70W in the test

A corresponding app for the Technics EAH-AZ70W is available for Android and IOS. This offers a lot of setting options. For example, several adjusting screws can be individually adjusted to the sound using the equalizer. Furthermore, the strength of the noise suppression and the permeability for ambient noise in the transparency mode can be precisely adjusted.

In addition, the key commands can be changed, the devices managed, and the battery level checked. The app is very versatile, and the setting options make the headphones the right choice for anyone who would like to adjust the sound and Co. to their preferences.

Speaking of key commands: The Technics EAH-AZ70W are operated via a touch field on the side of the plug. This already reacts to light touch. This has the advantage of not having to press the headphones uncomfortably into your ear when stopping a song. However, when you insert and remove the headphones, the disadvantage is that you accidentally come to the fields and unintentionally move something around.

Unfortunately, you can hear vigorous typing on the touch-field quite loudly in your ear. It is, therefore, necessary to operate the buttons a little more carefully. But once you have found out, the operation on the ear works reliably and easily.

Bluetooth – How stable is the connection of the Technics EAH-AZ70W?

Like most of the current true wireless headphones, Technics uses the modern Bluetooth 5.0 standard. Thus, once established, the connection is very stable and hardly affected by connection problems. However, the first connection with a second or third device is a little more cumbersome than the first pairing: The pairing mode must then be activated in the first few seconds after removing the plug from the charging case. This is not necessarily intuitive, and it is, therefore, necessary to look at the instructions. After all, the AZ70W can save up to 10 Bluetooth devices as players!

Once done, however, everything works fine. However, suppose you always want to use different devices in connection with the in-ears. In that case, you will not get a solution as comfortable as, for example, the Airpods in connection with Apple or the Samsung Galaxy Buds Live in connection with Android devices.

ANC – The noise suppression of the Technics EAH-AZ70W in the test

The premium headphones from Technics in the true wireless area have excellent active noise canceling. Admittedly, these in-ears cannot hide the outside world to the same extent as circumaural over-ear models. But for the type of earbuds, the Technics offer a very good performance that is well above average.

The plugs filter out outside noise using a microphone. As a result, constant noises such as a vacuum cleaner can be dampened very well. As already mentioned, the level of noise suppression can be adjusted with the Technics.

If you set this to the highest level, you can hardly hear any outside noises when listening to music. However, if you listen to audiobooks or podcasts, the outside world cannot be completely banished from your perception during the speaking breaks. Above all, irregular noise sources such as an announcement on the train or the doorbell can still be heard.

In addition to the ANC mode, the Technics EAH-AZ70W offers a so-called transparency mode. This allows a lot of outside noise to pass through so that you can, for example, talk while wearing the headphones. This mode can also be adjusted to the intensity. In terms of ANC, the Technics are among the absolute top models on the market.

Design – how handsome are the in-ears?

One of the reasons for the great success of true wireless headphones, in general, is the style aspect. Unfortunately, the Technics EAH-AZ70W makes a mediocre impression. Although the quality is solid and stable, the charging case and plugs are a bit clunky. The latter is still very noticeable when they sit in the ear. Whether that bothers is, of course, very subjective. However, other models find more elegant solutions here.

Conclusion on the Technics EAH-AZ70W

Perhaps the most neutral sound on the true wireless market currently comes from the Technics EAH-AZ70W. In terms of sound, the headphones come close to HiFi quality and also convince in terms of ANC and battery life, even if the case could offer a little more power here. The connectivity is very good, and the setting options are versatile. The design of the headphones, on the other hand, is certainly a matter of taste.
