DIY version up DIY 846 12BA ver. ▲ The photos are of the actual product. ● Unlike resellers, we offer a thorough warranty. We can handle repairs, replacements, 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, resulting in a clear and brilliant sound quality with excellent extension. You'll hear sounds you couldn't hear before, with a greater amount of audio information and a wider soundstage... The high-frequency extension, brilliance, and tight bass are all highly praised. The price is also lower because there's no brand premium from the manufacturer. Aging for 50-100 hours is recommended. It can be sufficiently driven by regular Hi-Res smartphones, DAPs, and computers. Even more performance can be achieved 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.
