Sleek-Audio is a new company that makes some very unique earphones – TechPowerUp
The build quality of the Sleek-Audio SA6 is really good. The only part that is prone to breaking is in my opinion the treble tube assembly because the darn things are so hard to pull out. Each time I swapped tubes it took me an awful lot of time and a lot of frustration. It is generally a good thing that the construction is durable and fits together nicely, but with no removal tool it is just a painstaking procedure trying to remove the treble tubes. Every other aspect of the SA6 is well thought out and the construction quality is right up there with the very best.
Sleek-Audio is aware of the problem and are working on a device that allows users to remove the treble tubes in a more safe and easy manner.
