Great Sound

After just seeing the cases I knew I wanted these. After getting them and listening to them I was in love with the sound. Then used them to listen to a hockey game I was amazed at the battery life. Over all great alternatives to my other headphones.

Visually stunning, aesthetically perfect

As with all gravastar products, the thoughtful engineering and sci-fi aesthetics not only make it a joy to own and use, they are light years ahead of their competition.
Crisp, refined treble. Warm spacial mid tones and tight, deep bass work together for excellent reproduction of most music genre's. Overall an impressive ensemble with the interchangeable cases being a wonderful distraction. However there is one caveat, the the shape of the earbuds don't fit aswell as the pros therefore lacking a little in full, all encompassing bass and passive noise reduction. All in all a fantastic product and would recommend to anyone.

Good but a problem

The sound quality is great, just like the Sirius pros, however mine have an issue with the bluetooth connectivity. Still good overall
