Summary: Has a good sound & battery life but noise cancelling mode only muffles, transparency mode has issues, and they have a poor user design experience across the board. They’re not bad for the price point, but I probably wouldn’t repurchase.Pros:- Comfortable- Good sound- Excellent battery life- No connectivity issues- Switches between multiple devices easily- Easy to adjust to your headCons:- Noise cancelling mode is certainly not noise cancelling, but it does muffle a lot. Not bad for the price point, but not accurately advertised- Transparency mode has a weird whooshing sound- L/R symbols poorly placed. The L/R symbols are inside of the ear pieces, so you don’t really see them unless you go out of your way to check. Putting them on the right way matters a lot since each side has different controls. I wish there was a tactile or at least more obvious externally visible way to distinguish between the left and right side. I want to be able to put them on without having to thinking about it. I also want to be able to put them on the right way in the dark.- Their tap to switch to transparency feature isn’t well designed. The feature is supposed to make it quick and convenient to hear someone talking to you, but I don’t think they fully followed through on that logic since switching to transparency mode via tap does not also pause what you’re listening. That kind of defeats the point of the feature in my opinion. Might as well take your headphones all the way off at that point.- The tap to switch to transparency feature is SO easy to accidentally activate when you’re just adjusting your headphones/taking them on or off. The placement wasn’t well thought through.- They have 5 rectangle buttons that all feel essentially the same, so it can be hard to keep straight which button does what. I would have loved to see some of the buttons be different shapes to help further distinguish them from each other.- I wish there was some kind of visible cue when they power on/off. Something like a brief light flash that is common in so many devices like these. The only way to confirm that you held the button long enough for it to actually turn off is by putting them back on to listen.
