These are garbage. I am on my second pair in two weeks, and they didn't even want to exchange them when I contacted them about issues until I threatened to file a chargeback.
The second pair arrived today, same issues; constant signal drops, and nearly every few minutes one or the other loses all sound. The range is 4-5 feet max if you are in the line of site, any obstacles forget about it (so much for being Bluetooth 4.x rated), and don't dare put your phone in your front pocket, it won't reach the earbuds. It's pretty common complaint on large sites like Amazon, just google it, and you'll see past the paid for reviews and fake news-style hype.
Oh and here's the kicker, they made me pay for return shipping for their defective product! Avoid and wait for a solid option from a reputable company.
Bottom Line: No, I would not recommend this to a friend
