First of all, I really like this design. Unlike most options in the market that comes with a somewhat thick case, the xS2 is petite enough to fit inside my pocket without causing a huge bulge.
The metal case feels really solid too, and it gives easy access to the earbuds. They’re just held together using magnets, so you do have be a little bit more careful while handling them. The earbuds have a rubbery skin over it which gives it more grip, and they do fit quite nicely in my ears. Not too tight, and not too loose. Your mileage may vary of course, but I’ve been using it daily while jogging, and I’ve never felt like they were going to fall out of my ears.
Even for longer sessions, they’ve never gotten uncomfortable at all. My only minor complaint here is the playback controls. Each earbud has a button on the surface. A single click for play/pause, double click to change tracks, and a few other options. The button is actually quite stiff, which means that everytime I press it, I’m essentially shoving the earbuds into my ears, which is not a comfortable thing to do. It’s not a deal breaker to me since I hold my phone in my hand while jogging, so I control everything through my phone. But I can imagine it being a little cumbersome for anyone using an armband for their phone. The other thing I want to talk about is the connection stability. For the most part, the xS2 works really well. But once in a while, I do notice a split second stutter in the audio if I accidentally cover parts of my phone.
But this could be down to the bluetooth performance on my phone as well, and I have noticed the same while using other bluetooth earbuds. I do want to mention a strange issue that I noticed with the xS2. Every now and then, the left earbud would just disconnect. This normally happens shortly after connecting to my phone, and if doesn’t happen, the connection between the 2 earbuds are normally pretty solid. So I’m guessing that it might just be a bug or what. It’s not a huge deal since I just need to pop the earbuds back into the case and then reconnect again. So, if you’re planning on using the earbuds without bringing the case out with you, just make sure they’re properly connected first. So I’ve been keeping track of my usage since I got the earbuds, and I’m really loving the battery life that I’m getting. After 2 weeks of use with around 24hr of total playback time, there is still battery remaining in the case. It’s way better than what I was getting from my older pair of earbuds, which I had to charge every couple of days.
For continuous playback on a single charge, I was able to get around 4 hours of playback, which is pretty decent too. The case itself can even double up as a power bank as well which is a pretty handy feature. That said, I’m not a huge fan of the use of microUSB. It would be nice to be able to charge my phone and earbuds with the same cable. I’m also not too sure how durable these flaps will be. Last but not least, would be sound quality. This is probably quite subjective since everyone has different preferences here, and I’m really not an audio expert.
So all I can say is that it sounds decent. For casual listeners or for sports, it’s more than good enough. The earbuds are able to get really loud as well which some folks will probably like. Compared to the other wireless earbuds that I’ve used, it’s around 30% louder. I also didn’t notice any significant audio delay while watching videos, which is nice.
You know, I’ve not tested nearly enough wireless earbuds to be able to tell you if the xS2 is worth buying or not. But what I can tell you, is that I’ve really enjoyed using these earbuds. It’s easy to carry around with me in my pocket, it sounds good enough, it has good battery life, and oh yeah, it’s actually IP67 rated. So I don’t even have to worry about getting these wet in the rain.
