I purchased these six months ago for $449 but they went from 18hrs battery life to 14hrs battery life in four months so I sent them back, my guess is that they had been sitting on a shelf for a long time and the battery had degraded. I'm not sure what Shure did but I sent them away to be looked at, now they are running for 18.5+ hrs after coming back from Shure but the faux leather has come away from the headband a few days after getting them back so they are sending me a new pair but I have already replaced these with a set of Gen 2 Aonic 50s as it took a long time to get them seen to by Shure so these are surplus. Charging is also taking a lot longer than advertised. They sound good and are really comfortable. There is no warranty implied or given.

The Shure AONIC 50 are wireless noise-canceling headphones designed to provide studio-quality sound with a sleek and comfortable design. They feature a closed-back construction with dynamic drivers measuring 1.97 inches (50 mm) and neodymium magnets, offering a frequency response of 20 Hz to 22 kHz. The headphones support multiple audio codecs including AAC, LDAC, SBC, aptX, aptX HD, and aptX LL, and they come with a 3.5mm audio cable for wired operation as well as a USB-C cable for charging and high-resolution audio streaming. The AONIC 50 also includes an Environment Mode that allows users to hear external sounds while still enjoying noise cancellation. They have a runtime of up to 20 hours and are made of anodized aluminum and premium materials, ensuring durability and comfort.
