LIN HiFiイヤホンアダプター

The sound is now clearer than the original Apple headphones! I think the sound quality has improved, but I think it's just a placebo effect! Since I bought the LIN headphones, I've been enjoying listening to music every day and have been wearing them all the time.

When comparing the sound from the headphone jack on my PC (Windows 11) (S1220A chip + OPA1688) and the MOTU M4 headphone jack, there's a slight thickness in the low to mid-low range. Compared to the Apple USB-C adapter, there's also a slight thickness in the low to mid-low range. Perhaps because of this thickness, the EarPods' shrill mid-range (2KHz-4KHz) sounds a little milder. When I connected 300�� headphones (Sennheiser HD600) to the PC's USB connection and turned the volume all the way up, the volume was loud enough to be annoying. I connected the Apple EarPods 3.5mm and tried using the remote control on my PC, and play/pause worked, but volume adjustment didn't. The Apple USB-C adapter allows play/pause and volume adjustment. I was able to record at 96KHz/24-bit using the free software Audacity. I was also able to test record Skype. While the price difference with the Apple USB-C adapter is ?1000, if you only want to play music, I recommend this product. 1. It can play high-quality PCM recordings. 2. This product's cable is more durable than the Apple USB-C cable, reducing the chance of having to replace it due to cable damage. It was shipped from China, but it arrived in 8 days. You'll also receive a shipping number, so please be patient. In China, the "Singles Day" sales period begins around November 11th, so delivery times may be delayed. Delivery times may also be delayed during the Lunar New Year (February). Regarding compatibility with iTunes on Windows, this is not a product issue (I think). When using this product with Windows 11, it uses Microsoft's standard Windows drivers. This product can play audio up to 384KHz/32bit, but the maximum sample rate in iTunes playback is 192Khz/24bit. Therefore, if you set the Windows driver to 384Khz/32bit and launch iTunes, no sound will be heard. To hear sound, you must change the iTunes output device from the default to USB-C Audio in the volume mixer. If you find it inconvenient to change the app's audio output destination in the volume mixer every time, you can simply set the driver to 192Khz/24bit and audio will play from iTunes without changing the settings.

I was planning to use it with the Sennheiser IE100 Pro and QDC Superior, but the output from this DAC was too loud, and honestly, the sound just sounded rough. However, when I switched to Sony headphones (MDR-100A) with a slightly higher impedance, the volume was just right and the sound was very delicate. Personally, I thought it might not be suitable for low-impedance products.

Although it's pseudo-balanced, it has a sense of depth and the sound quality is good. The small size of the device means it doesn't get in the way. I think this size is sufficient for listening to wired earphones with a smartphone.

I bought these because the ones I was using broke. The sound isn't as good as the Fiio KA11 I was using, but considering the price, I think they're doing a good job. If you care about sound quality, I recommend spending a few thousand yen more and buying the KA11. On the other hand, if you don't care that much, I think the quality is satisfactory.
