The electronic work kit "Earphone Aging Machine Kit" made only for aging earphones is on sale at Ken-chan, a home appliance. The price is 2,300 yen including tax.
The kit is manufactured by the circle "fixer" and is sold as a product without any support etc., and it is a model for people who have some knowledge of electronic work etc. (Soldering work etc. for assembly) Is necessary).
The store demo machine in the photo comes with an acrylic plate and spacers, but these are not included in the kit and must be prepared separately.
People who are particular about it will age when they buy high-end earphones and high-end headphones, but it will be a little inconvenient because DACs and amplifiers will be occupied.
This kit was created to eliminate such troubles, and it is a kit that can continue to output noise signals for aging as long as it is powered by USB.
The earphones / headphones that can be connected are those with a 3.5mm jack. The power output from the kit is about 1μW to 0.1mW, and it is said that "there is no worry of damaging the earphones due to excessive input".
Sold as a kit that requires assemblyIn addition, the kit does not guarantee the effect of aging, and there is a disclaimer that "I do not know if it really has an effect on aging", but the output noise signal has a power spectrum distribution close to the actual music signal. It is said that it is a random noise signal that it has, or that if you do not feel the effect, you can program an arbitrary signal generation pattern by preparing a development environment for the microcomputer, and you are familiar with this field. There is a feeling that it was made by a person.
When I purchased the SENNHEISER HD800 headphones, I used a CD called "Test & Burn in CD" to age the DAC and amplifier, but it was inconvenient because the equipment was occupied. By the way, I couldn't feel the effect at that time because I had a bad ear, but it makes sense to do it! I was satisfied with that (laughs). If you are aging only earphones and headphones, such a kit may be convenient.
