The difference was BIG. My only disappointment was 2 days after I ordered these shoes, they went on sale for a few dollars less. If I could get the particular navy ones I wanted in my size, I would have 3 pairs now??! Thank you to this wonderful seller. I have used them on my phone and laptop for about a week now, both connect easily and with very decent sound quality for both video and calls. Then I put it in the PC and now Im getting stereo when the jack is pushed in fully. Build quality:Awful, cheap thin plastic casing. Ordered size 5, true to size. Whatever it is, only Vol - works, Vol + calls up a prompt on screen asking which assistant youd like to use. Less than 6 months of use!
