I’ve got both (Cardas and Nighthawks), and sound is similar - rich, dark, great bass detail. These bathe you in sound rather than shower you with detail - I feel like i’m listening to speakers rather than reference iems, so Cardas marketing this as an EarSpeaker is not innacurate. Particularly enjoyable for live jazz and darker orchestral recordings. A little eq can resolve the treble followed and lightens these up a bit when needed. Comfortable for long listening so long as you aren’t moving around, due to relatively thick and heavy cables (definitely not for mobile use for this reason, but I’ve experienced no problems with microphonics, and I also wear cable “over ear” which resolves cable weight issues.) The fixed cable would sell for well more than this $99 alone. I’m not going to weigh into the “cable” debate here, but if Cable’s are important to you check Cardas website for info on factory mods to convert this cable and iems to MMCX or your preferred termination, and you will have a serious audiophile cable for home listening with this and your other iem gear, and you can make these earphones mobile with a lighter cable. If you think this is your thing, call Cardas before you buy, as this fix is likely to double price of this product and could take a while, but for some it may be more than worth it. When these first came out a number of audiophile reviewers didn’t blink at the $500 list, and even with the cable mod you still get home for about what I happily paid for my set ($250).
