For context, I have the 2nd gen AirPods and have been a bit paranoid after I lost a pod while exercising and had to get a replacement. I was looking for a cheaper alternative to use regularly and I gotta say I am thoroughly impressed by these. Truly a bang for your buck. Here are some of the top features;
1) This is a good fit for working out. The earpiece really stays in even with sweat and a lot of movement. I'm glad to say that these are my next pair of workout earphones.
2) This is pretty hard to beat at its price tag. It's not the greatest quality, but keep in mind you are paying $30 and I think its value is more than that.
Some critique I have is that it doesn't have some of the more advance features of other wireless earphones, like auto-pausing when one bud comes off. But that is fully expected given its price. Also the charging case is a bit flimsy but definitely does the job.
