Up for sale is a very rare AR-3 mid-range driver. This is an earlier version of AR-3 mid-range driver. This AR-3 mid-range is made of huge alnico driver and it’s very heavy. Connected AAA with battery and produces sound. That’s all I can do for testing. Based on my test this driver appears in proper working condition; however, no guarantee. Please review photos closely as they are part of description. What you see is exactly what you get. No return is accepted.

Technics wireless earphones magnetic fluid driver Bluetooth silver EAH-AZ100-S. Technics’ proud acoustic technology concentrated in a completely wireless earphone In pursuit of even higher sound quality, the same technology as Technics’ flagship wired model EAH-TZ700, the “magnetic fluid driver, ” has been adjusted for completely wireless earphones. By fully combining high-quality sound technologies such as “spatial design” and “circuit design, ” we have achieved excellent spatial reproduction over a wide range from ultra-low to high frequencies. The EAH-AZ100 was completed with the aim of reproducing music that conveys the artist’s thoughts as they are. High sound quality with magnetic fluid + ultra-thin edge + special aluminum diaphragm Magnetic fluid is a magnetic liquid that is placed around the voice coil that drives the diaphragm and supports the diaphragm. In addition, the edge that supports the diaphragm has a soft ultra-thin edge structure, expanding the amplitude range of the diaphragm. On the other hand, the diaphragm material is made of highly rigid aluminum, which allows it to reproduce a wide range of frequencies from low to high without fine deformation even with intense movement. Newly developed adaptive noise canceling Adjusts to maximize noise canceling performance according to the surrounding environment and the shape of each individual’s ears. Compared to the previous model EAH-AZ80, the noise canceling performance achieves better noise reduction, especially in trains and airplanes, and more powerfully removes noise and people’s voices in the ears when noise canceling is enabled. “Voice Focus AI” for clear sound when receiving as well as when transmitting Equipped with a new function “Voice Focus AI”, the industry’s first function that removes noise when receiving as well as when transmitting, to remove noise. In addition, it also achieves power saving, allowing for 6 hours of continuous talk time, allowing for clear, stress-free conversations during long online meetings. The first fully wireless earphones to feature AI-based reception noise removal using a built-in IC chip. Product released on January 23, 2025. 10-hour battery life for peace of mind when you’re out and about You can enjoy music playback for up to 10 hours with the earphones alone, and up to 28 hours with the charging case. It also supports short-term charging, allowing for approximately 90 minutes of continuous playback with a 15-minute charge. In addition, with noise canceling OFF and AAC, it allows for approximately 12 hours of continuous playback, so you can rest assured even when you suddenly go out. Even smaller and slimmer concha fit shape The concha fit shape that fits into the concha (concha), the depression around the ear hole, to hold the earphones has been inherited from the previous model EAH-AZ80. While maintaining the unique shape derived from ergonomics, it has a more compact and slim shape. The weight of the main unit has been reduced from 7.0g of the EAH-AZ80 to 5.9g, resulting in a 16% reduction in the main unit weight and a 10% reduction in the main unit volume. No need to switch, multi-point connection for 3 devices If you receive a call from your smartphone while in an online meeting or watching a video on your computer, you can smoothly switch to the multi-point connection by answering the smartphone. Multi-point connection is possible for up to three devices, including not only PCs and smartphones, but also tablets. Compatible with wireless charging “Qi” Compatible with the wireless charging standard “Qi”. Simply place the charging case on a commercially available charging stand to automatically charge. Splash-proof specification equivalent to IPX4, so you can use it even in sudden rain The earphone body has a splash-proof performance equivalent to IPX4, so you can use it in sudden rain or sports scenes where you sweat. This unit earphone body only. Excluding the sound guide tube (sound outlet tube), ventilation hole, and microphone hole of this unit. About other area, please ask me.
