Of note, I've been using this product for only about 1 week and I received this product for an unbiased review. In order to post an unbiased review, I am reviewing this product as if I had paid the full cost of the product (Currently listed on Bestbuy at $49.95).
Overall, I love the concept and sound of the headphones. The speakers of these headphone sit in front of your ears and not in your ears. If you're looking for noise-canceling or sound isolating headphones, this is not the right product. But if you don't mind being aware of your surroundings, these work great. If the volume is high, you may not be able to truly hear what people are saying, but if you set it right, you can definitely alternate your attention between music and outside speech, which is awesome. This would make it perfect for driving or biking, when you don't want to be completely isolated from the environment. In regards to the quality, I'm not an audiophile, but these sound really good. The sound is clear and it has nice bass. An interesting thing about the bass is that it vibrates on your head a little, which is kind of cool but also kind of feels weird. The battery life is pretty good and you can listen to quite a lot of music on one charge. Overall the feel over the ears is comfortable and it's pretty light weight.
Now the down sides. First, the cover for the charging port is annoyingly difficult to remove. If your nails are clipped and you don't have something really small to stick under the cover, it will be very hard to take off the charge port cover. Another down side is the cord length on the "distal" side of the battery (the side connected to the 3mm jack) -- it's only about 2" long, and I wish it were longer. But the overall cord length is fine. A third con is the LED that indicator. When turning the device on, it turns blue for a second, and then turns off. I have frequently forgotten to turn the device off since the LED doesn't stay on when the device is on. I would like to see the LED stay on when the device is on.
Bottom line, a very cool concept and good sound, but if I'm paying $50 for headphones, they should have these annoying quirks about them. I think if those quirks don't bother you, it's definitely worth the purchase.
Again, I am reviewing this as if I paid $50 so that the I can post an unbiased review. This is a review for the AfterShokz Sportz Titanium Bone Conduction Headphones that I received free of charge to do a beta test and review.
