I really expected more when I purchased these, I purchased them the moment they dropped and I was quite excited. The only real gripe I have is slight microphonics in the cable - if the cable touches your shirt or face you can hear the vibration. The weight limit is way more than enough for two bikes, unless youre riding with some serious components or accessories. It served me well for the 18th months I lived in the Silver State. 5" that is a huge difference. 5 hours later, I am actually energized and have 3 more hours to go. Monoprice refunded the price in full. Pairing with my Blue tooth phone and tablet is automatic and quick. And the second time I put them on I knew that I would be just fine stepping into them. One thing I want to note is the size.
