Aonic Free's Crimson Red
Sure Japan's complete wireless earphone "Aonic Free" is an orthodox, but is a very interesting product.In the announcement on November 4, one color of the graphite collar was announced, but today on November 18, the Crimson Red Colorable was prepared, and the two colors were released.

First, from the basic function.Surprisingly, Aonic Free is Sure's first completely wireless earphone.To be precise, there is a model called "AONIC 215 TWS", which combines SE215 with left and right independent wireless adapters, and a second -generation machine has appeared.However, this is the first product that integrates communication portions such as antennas on the main body, such as a general complete wireless earphone.

Sure's site does not disclose technical information about chips.However, because it supports APTX, it seems that the Bluetooth chip made by Quarcom, like the already released Aonic 215, Gen2, etc., is adopted.On the other hand, the generation does not seem to be the latest because it does not support the latest technology of Qualcom, such as AptX Adaptive.
In many cases, Sure is used for older generations with high stability and prices rather than actively adopting the latest chips, so this unit may be in accordance with that idea.
The body is quite large for a complete wireless earphone.The width is 3.About 5cm.Sony's previous generation model "WF-1000XM3" was about 3cm, so it's a good idea to imagine a slightly larger size.
Compare with SE215.The shape and size of the part that touches the ears are close.
Equipped with one dynamic driver.From the flat part containing antennas and substrates, the part to be put in the ear protrudes.The shape and size here are quite close to SE215.The housing structure is the same as the wired IEM, but in parts such as the feeling of wearing and sound insulation, you can expect the same performance as existing earphones.The attached earpiece is a low -resilience type.This also leads to good fit.
According to the included instructions, the frequency band (21Hz to 17).5kHz), sensitivity (107dB) and impedance (20Ω), equivalent to SE215.
