Drop x Sennheiser HD 58X Jubilee through a Qudelix 5K. Both are great pieces of kit, the Qudelix especially. The onboard parametric EQ combined with AutoEQ is fantastic. However, after running a hearing test and enabling Hearing Assist, the EQ on the Airpods is incredible and everything sounds very natural. I have no idea how they managed to get this much soundstage and bass out of these things. I also have a pair of Grado SR 80, and have a soft spot for Koss KSC 75.
FWIW I got mine at Costco and their return policy is top notch, and I believe they include AppleCare+ with the purchase. I had bought my APP2 fairly recently before the APP3 were released, experienced buyers remorse, but had kept them in like new condition with the box and accessories, and had no problem exchanging them.
