I personally love them. I’m not familiar with connection issues but battery certainly drains inconsistently between buds. I haven’t had issues with draining in case, although I think others have mentioned it. When using them, start at 100/100, but by time left side is at 50 right is 40. Last I heard from Devialet they’re working on a fw release for this quarter.
Driver flex is an issue. I only use low transparency and low ANC to mitigate the popping sounds that come with movements. Doing that really controls it for me. That said, when walking around I do have to adjust them every once in a while.
Sound wise I think they’re fantastic. I don’t get fatigued either. ANC is stellar even on low, much to my pleasant surprise; both indoors and out.
No surprise, I feel case is too big.
Edit: what do I mean by fantastic sound? The high hats and snares are so detailed. Bass is strong and punchy but doesn’t hide other frequencies. I can hear the bass guitar, not just the boom it creates. Mids/vocals are strong for me. I listen to the likes of Amy Winehouse, Phish, Bob Marley, Lettuce, Soulive, Grateful Dead, Pink Floyd, Miles Davis, Charlie Parker. Use Apple Music and SiriusXM
