earphone 3.5mm+6.3mm jitter

      This release also introduces a premium QSA series headphone adapter, delivering enhanced performance. while also offering a ‘remote noise reduction’ effect. The QSA adapter functions similarly to a grounding noise suppressor. When connected to playback devices with headphone outputs—such as headphone amplifiers or digital players—it effectively absorbs faint noise and suppresses EMI/RFI interference on any device with a 3.5mm or 6.35mm jack. This achieves dual enhancements: noise reduction and improved sound quality. Once connected, the background becomes as dark as midnight, with a markedly improved signal-to-noise ratio. Subtle sound effects and spatial reverberations become distinctly discernible. Consequently, even when not paired with headphones, the QSA adapter delivers commendable results, rendering vocals with compelling expressiveness and a remarkably sweet timbre.

     For the average consumer, QSA products may seem prohibitively expensive. Yet they offer audiophiles a fresh upgrade philosophy: sound quality improvements don't necessarily require blind pursuit of high-end main components. Optimizing power handling, interconnects, and other critical details can yield disproportionately effective results. For audiophiles pursuing ultimate sound quality, QSA's flagship products stand as an indispensable, ultimate choice. With their unique technological advantages and significant sonic enhancements, they have become benchmark products in the high-end audiophile community.

      本次推出还一款顶级ultra cgr系列的耳机转接头，效果更佳，同时还有“隔山打牛”的功效，就是QSA的转接头还有类似于接地降噪器的效果，将QSA转接头接入带耳机输出的播放设备例如耳放、数播等，只要是带有3.5mm或者6.35mm接口的设备都能有效吸附微弱噪声、抑制EMI/RFI干扰，实现降噪与提音质的双重提升。插上之后背景黑如深夜，信噪比显著提升，细微音效与空间残响清晰可辨。所以即便不连接耳机使用，QSA转接头依旧有不错的效果,人声很有感染力,而且非常甜美.

      对于普通消费者而言，QSA 的产品或许价格昂贵，但它为发烧圈提供了一种新的升级思路 —— 音质提升不一定需要盲目追求高端主设备，通过优化电源处理、连接配件等细节环节，同样能获得事半功倍的效果。而对于追求极致音质的发烧友来说，QSA 的旗舰产品则成为了无法绕开的终极选择，其凭借独特的技术优势和显著的音质提升，成为高端发烧圈的标杆性产品。
