First Pair of IEMs
My recommendations: SennheiserIe600 - v similar to your hdb630Ie900 - More refined but ie600’s tuning to me feels more exciting for all genres For both models, the cable to iem connectors can be a little loose (based on the ones I have) so be careful. What appeals to me most is how small they are si

Just bought a couple of gifts for myself

Over ear headphone recommendations.
As a follow-up, the mid-range Sennheiser's get a lot of love: 660S2 (https://www.crutchfield.com/p_143HD660S2/Sennheiser-HD-660S2.html?tp=60835)560S (https://www.crutchfield.com/p_143HD560S/Sennheiser-HD-560S.html?tp=60835) If I were to get another set, I'd probably look at these. I like open-back hea
