I’ve learned with Bluetooth stereo wireless headsets, it takes some actual used before it’s worth forming a solid opinion. I say this because I’ve now been through approximately five different sets of headphones in the last 14 months or so.I’m going to give these five stars after many months of use, and many months of my wife’s direct use, particularly in light of the current price on Amazon which is shockingly low for what you’re getting.Here’s what I like, or why I think they are an incredible value. Sound quality is perfectly acceptable, even quite good, overall balance from my perspective is good. It is not heavy on the base, overly tinny on the highs, and also not muddy in the center. Just good balanced sound but of course this is not going to rival anything over $75 for example from a reputable manufacturer. Wireless charging, speaking of the actual case on a wireless charging pad, has been awesomely reliable. That is how we charge these 99% of the time. Use of either ear has been excellent and consistent. What I’m trying to say here is that we use one ear and one ear only all the time. Right or left it doesn’t matter these Bluedio’s seem to figure it out and work just fine either way. They also do a good job of pairing for Stereophonic sound as well when we want to use both of them at the same time. Battery life is decent, I would say about on par for these kinds of products which equates in my personal experience to about 4 to 6 hours of continuous use. Everything seems to charge pretty quickly in the charging case although this is a smaller case so I don’t think you could probably go through multiple cycles of charging these headsets without actually charging the case itself. That said, I haven’t spent a lot of time checking that, because we’re always pretty good about charging them basically every night. Oh and I hope that last statement is clear, we charge them every night because they get used essentially every single day during my wife’s workouts. This equates to both in house working out, as well as long walks and jogs outside. And I guess that’s also a good segue into the last point, these have been very reliable to pair easily with different phones and I’ve given us no trouble on the Bluetooth side of the equation. And that’s not saying something without experience, between my wife and I we have cycled through four or five different phones over the last few months and these have paired easily with all those phones. Finally, although we’ve not actually used these for a lot of phone conversations (because they’re mostly used in the morning before work hours begin ) the ones we have had have worked fine, with people indicating they can hear us acceptably well.The only negative I really have to report is the light on the case. It is blindingly bright if you’re going to have it on your bedside at night. It stays lit green while it’s charging and it’s just annoyingly bright.Overall, and incredible product at an incredible price or value.
