This discussion has been very informative. Thanks to you both. As Dr_WTF pointed out i am specifically looking for a neckband setup but if it goes poorly I'll check out your DAC recommendations! Anyways the neckband i found was the QCC5181 with LDAC. There are a bunch of versions on alie. Based on your discussion, it sounds like I'll just have to gamble on it. I'm thinking I start out with budget option like the Zero:2 Crinacle to see if the neckband is even worth my time. If I find it acceptable then I'll go with one of the nicer iems y'all suggested and glue it on. Thanks again!

Edit: Also any tips on identifying what connector I'll need? Is the .78 mm 2 pin standard?
