Hahah very true. I did my testing in a quiet office environment.
That said, I just inadvertently gave my BTR1 away. Fiance just came up to me and asked if I have a spare iPod Shuffle so she can use for working out. I said, yes but I left it at work. She's like oh, can you get it for me. I'm like sigh... how about you use this bluetooth adapter for now and we can pick it up monday? I hand her a cheap $10 bluetooth adapter which is still 4.2 and has Apt-X (she uses iPhone 7+ so doesnt really matter anyway). She's basically says, "meh." Then, because I dont really want to go into work even though I''m probably going to have to anyway for real work, I said, well you could try this: pulling out my BTR1 from my bag. She''s like oooh whats that? So I explain to her it's also a bluetooth adapter and it's got some fancy gizmos inside of it that makes it sound pretty good and then demonstrated to her how it works. She reaally like the size, shape and the clip for working out. So she's like, "well, I'll take that, thanks! Can you get me one too?"
Sigh, so there goes my BTR1. The good news, she found out I bought something without her knowing and didn't care. The bad news, she really liked the phantom purchase and hijacked it from me.
