soundcore Space One Pro by Anker, Adaptive Active Noise Cancelling Headphones, Super Foldable Design, 60H Lossless Audio, Ultra-Fast Charging, Hi-Res Wireless Audio with LDAC (Jet Black)

I already have two Anker Soundcore products and wanted something with a bit more oomph. What I got was something with a lot more urgh.Firstly. Disappointingly for the price, the pouch that comes with these headphones is woefully inadequate.The first time I used them was while running on a treadmill at the gym. The sound was great for a time, then after a while I started to hear something like feedback behind the music. I turned them off and on again, which initially seemed to sort it, but the feedback sound returned suddenly and with disorienting ferocity. It was like a bird screech mixed with nails on a chalk board in one ear. I turned them off and on again, the noise was gone, but the volume in the right ear was noticeably lower. Then after a while, during a particularly quiet song, despite having the ANC turned on, I came to realise that I could actually hear the gym’s music playing behind behind my own.I took the decision to return them. I’m extremely disappointed in these as they are quite a costly product and has somewhat damaged my trust in these products.
