:-) I tried the K371s 1st, in that I also have the K553 Pros. At first I believed the earphones defective until I realized that they have an on and off switch and a pause button. I tend to have good luck with Steve Madden shoes, Ive had several of his brand in the past and they really hold up very well, so they were worth every penny spent. I did buy a second pair about 5 months after Christmas so I could rotate them like you should with all footware and when the day comes that these wear out, unless they have a better version at that time, Ill be buying another pair of three. These were unavailable in white in size 2, so I ordered 1s and was very pleased that they fit with room to grow. The 7 fits me exactly like the 6. I think the sets are incomplete or the description is wrong. The size 9 Juxt is fine. But, when I put them up on my car I had to widen the front crossbar. Sound quality is good, but I do wish there were equalizer control available through the Mobvoi app.
