Again, I am very thankful to have the 840 set. Wi-Fi connectivity is very fast. The sound is amazing for such small earbuds. Two, the in-line remote control has broken off a bit at one end and seems quite flimsy. I will also say that they get scuffed quite easily but because it is a matte color, I don’t think it’s too noticeable. I was pleasantly surprised to find 2 cables in the package. It is suprisingly sturdier than I expected. The flywheel supplies enough momentum that you transition smoothly into the climbs, as you would on the road. It’s a great piece of decor. If you want this for a galaxy S8 with a slim case, Id recommend getting a case for a larger phone.
