I bought these to replace the ear tips on the 10hr battery life - Arbily Bluetooth 5. I am a Yellow Box junkie - I dont want to admit how many pairs I own, but its more than how many toes I have :-) I love that Yellow Box is usually so consistent as to size, I wear a 6. A 67 year old 160 lb male is using this ball and it burst. For the price you pay, this is a great pull up and dip stand. I had to use the smallest in ear attachments and I still dont feel it fits that well but that could just be me. Love the color, and they are way more comfy than I thought. I always get complimented on these shoes because they are truly unique. I know they think I?m crazy at work for the past 2 weeks I have been switching between the two throughout the day. The configuration is a time-consuming and mostly manual, but is extremely powerful and not difficult to figure out. Here is a snip from my chat with the first Samsung rep:Me: I just got my new Active 2.
