1.希望使用质量好的TRS端口,使耳机插入有段落感。2.还有切换歌曲是独立按键还是长按?3.是否考虑使用ess9218p芯片基础上加入opa1622运放改善听感呢?就像中国产hifi手机xplay6那样的效果?

1. we use the best parts, including a reliable 3.5mm connector.
2. Yes, 5K has four multi-functional button for vol+/- and playback control.
3. ES9218p provides the best enough output power and sound quality. Unfortunately, assuming the current battery time and price budget, we don't think additional OPA1622 would fit for the current version of HW design. We'll check it out and keep it in mind for the next product anyway.
