DIY version up DIY 846 12BA ver. ▲ The photos are of the actual product. ● Unlike scalpers, we offer a thorough warranty. We can handle repairs, exchanges, fine-tuning, and custom configurations! The internal components are not Chinese-made BA drivers, but original KNOWLES units. Detailed Configuration: High Frequency: TWFK-30017 x 2 Mid Frequency: ED-29689 x 2 Low Frequency: CI-22955 x 2 While the SE846 has 4 drivers, this one has 6 BA drivers, so the low frequencies, which were a challenge, are reproduced cleanly across the entire range. The high frequencies are handled by the well-regarded TWFK, providing a clear and extended sound quality. You'll hear sounds you couldn't hear before, with a greater amount of audio information and a wider soundstage... The extended highs, brilliance, and tight bass are all highly praised. The price is also lower because there's no brand premium from the manufacturer. We recommend aging the product for about 50-100 hours. It can be sufficiently driven by regular Hi-Res smartphones, DAPs, and computers. You can get even better performance by using a portable amplifier. This product is not an SE846. In my subjective opinion, I definitely recommend this over the SE846 in terms of cost performance.
