I have posted this review on Amazon.ca, and will link it to my twitter account.
I am a runner. I run on my treadmill for 6 miles a day. Trying out this pair of earbuds has given me the chance to be wireless while running. There were three things that I wanted to test in the Spirit X. 1. Are they Sweat proof? 2. Are they comfortable? 3. How do they sound? Here is my review.
These are sweat proof. No doubt. While I wouldn't recommend it, you could shower with these on. I sweat more than most people, and simply wiping them off with a towel, they were ready for my next run. Don't believe me? You can simply immerse these in water, and if for some reason they don't work anymore, Anker will send you a new pair.
These are comfortable... for a time. Trying to wear these for a long period of time, I find them to be a little uncomfortable. They are big and bulky, and the buttons are initially hard to navigate. There are three control buttons that I find difficult to use while running. They have not fallen off while using them, which is a huge plus when running. Other earbuds I have used have fallen off multiple times.
Sound quality is good enough for me. I find this to be all about preference. Some people want more bass, and more whatever... but really, this pair of earbuds is meant for sport enthusiasts, not for music buffs. I am sure there are better sounding units available, but for a rugged, sweat proof pair of earbuds, the sound is sufficient.
There is my review. Feel free to ask me any questions about my experience with the Anker Soundcore Spirit X
Thanks for the opportunity to try these out! - Jay
