【Product Description】 ■ Overview: This is a listing for the INAWAKEN "Twilight-DS," boasting an astounding specification of 12 drivers (4DD + 8BA) on one side. I purchased it new on AliExpress in November 2025, but I am selling it to streamline my equipment, considering its compatibility with my existing gear. ■ Background of the Listing (Sound Quality & Compatibility): I was listening to it with my FIIO M17. This unit has extremely high resolution and a cool-leaning tuning with a lot of information. Therefore, when combined with the M17, which also has high resolution and a monitor-like tendency, the sound became too sharp ("resolution x resolution"), and it differed slightly from the sound I was looking for. However, when I listened to it with a portable amplifier with a vacuum tube (such as the iBasso PB6) that I had previously, the abundant resolution was complemented by a gloss and warmth, producing a very musical sound. ■ Notable Point: Quality of the Original Cable: The included cable is of very high quality, and it can be said that there is no need for a replacement cable. High-grade wires using "high-purity OCC (single crystal copper) + alloy copper" are used, transmitting the powerful low frequencies of the 4DD and the delicate high frequencies of the 8BA without any loss. A 4.4mm balanced plug is also standard equipment. ■ Condition and Aging Usage Time: Approximately 5 hours in total (only used indoors for listening). Smoking: Non-smoker Condition: No scratches or stains are found, and it is in a very clean condition, close to new. About Aging: Because the usage time was extremely short, the full aging process has not yet been completed, and it is in a fresh state. Since the "tension" of the drivers still remains, it is ideal for those who want to break it in slowly. ■ Regarding Hygiene (Important) The included ear tips are "completely unused" in all sizes. (When listening, I used my own aftermarket ear tips from the beginning. The original ones have not even been taken out of the bag.) Those who are concerned about the hygiene aspects unique to used earphones can use them with peace of mind. ■ Accessories (Complete) Earphone body Original high-purity OCC cable (4.4mm balanced) Original ear tips set (all unused) Case Original box, instruction manual ■ Shipping is possible within 24 hours of purchase.
