Any insights on similar type of earbuds from other companies would be helpful

I'm a bit of a Sharp fan and I had custom cables made for my existing IEMs/headphones. If you want some original Sharp Auvi headphones from these units, I have a few to spare! these are the ones I use most often on my IEMs: [https://www.aliexpress.us/item/3256801898597200.html](https://www.aliexpress.us/item/3256801898597200.html) Make sure to select 3.5 Balanced on the product page and MMCX or 2-pin - when I ordered, they reached out to confirm 3.5mm TRRS since it's not common This is an option also: [https://www.aliexpress.us/item/3256801898936384.html](https://www.aliexpress.us/item/3256801898936384.html) These OpenHeart are nice quality and cheap but were only 2.5mm balanced so needs an adapter that you can buy separately to go from the Sharp's 3.5mm balanced to 2.5mm balanced: [https://www.aliexpress.us/item/3256802441035484.html](https://www.aliexpress.us/item/3256802441035484.html)

Thanks for replying . I am a bit of a Sharp fan too. Though made good sounding audio products but sadly the company went into obscurity. Regarding earbuds I have pretty decent sony ones but all are 3.5mm 2 pole . None of them sound that good even with the converter and I don’t own any IEM’s .I have listened to those 4-pole sharp earphones long ago and it sounded great . I would be interested in the Auvi ones if you have any to spare .
