唔係同你拉去煲耳機 係想同你講universal都有可能唔同聲 要concern既因素多到數唔完
而且justear同fitear咪又係全cm咁做 唔係否定你講既野 但係覺得你諗太多
This is in response to our valued customer and member of the 64 audio family @crinacle, as well as @echineko and the rest of the Head-Fi community.
First and foremost, we are very sorry to hear about your experience with your custom N8. We want to help and will do everything in our power to rectify the situation.
We believe with all such situations there comes a silver lining. That silver lining is the opportunity to learn, to improve, and ultimately, to make our customers happy. After thoroughly investigating on our end, we believe we understand why this happened and will confirm when we get the unit in for investigation and repair.
To answer questions regarding the tuning as seen in @crinacle’s custom pair, and whether it is intended going forward, the answer is, no. This was not the intended tuning. The two sides matching could be the result of performing the same process to both sides during production. Our demo units provide the intended sound signature and we translate that signature to all custom units. The custom and demo should look very similar across the frequency spectrum.
The N8 is a special product in our lineup. It shares a tubeless low frequency dynamic driver similar to our Fourte and Trio products. After thorough investigation, we believe that the discrepancy in sound signature is most likely caused by a difference in air volume inside the shells. In the design stage the original tuning of N8 was achieved with a representative internal air volume of the shell based on an average ear size. This translates consistently to the demos because they use a universal shell that is properly sized for this average internal air volume. Early on, we suspected that there could be changes in the low frequency response of custom N8’s depending on the actual air volume of shells among different customers. However, we ran tests in the development stage that showed only slight variances among different shell volumes that fell within our established tolerances..
Although more investigation is needed, it is possible that
