Since I don’t have the black ones to compare with, my expectations concerning the blue color resulted from exactly those pictures you provided. So, I knew, they wouldn’t be royal blue and also preferred it this way. But compared to my other black headphones there simply is no difference at all. BUT: I took them out today. And now it’s obvious, they need uv-light to show their blue color. They look blue outside, but totally black with indoor-lighting. So I guess, that’s just how they are manufactured which is a bit disappointing for me bc I am an indoor-user. I wouldn’t wear them much outdoors. For that I do have the JBL Tune 500BT which btw. totally influence my judgement concerning headphones. I have tested lots of headphones and none of them provided such a good ‘out of the box’ sound. I know, this is totally subjective and they could be crap. But they totally satisfy my listening expectations as someone who’s not audiophil, but likes to have headphones that sound decent with any genre and also language. If you look for cheap headphones for ‘rough’ outdoor activities, etc. those are the ones that will probably not disappoint you. They are 29,- € at Amazon Germany right now. They have mulitpoint-connection which works excellent, and - although only 4.2 bluetooth - great BT-range (haven’t tested better ones, except for the Q30 which is on par) and really good microphone call quality (better than Q30). Oh, and they get way louder than all the others, including the Q30. The only reason I had to look for another pair of headphones was bc they’re ‘on-ear’. They’re getting too uncomfortable after a short time.
Ok, that was a bit off-topic now. But maybe it helps those who look for a second pair of cheaper headphones to have in stock.
Btw, I bought the soundcore Q30 for 63,- €. Maybe price will drop even further, but I didn’t want to wait any longer, especially since it might also go up again for a long time.
