Sleek-Audio seems to have struck gold with their exchangeable tubes and ports. The fact that you can customize their audio performance is just an incredible feature. What never ceases to amaze me is that these earphones offer such a degree of customizability while preserving an excellent build quality and an extraordinary level of performance. I initially thought that these earphones were more of a gimmick than true performers, just like the array of customizable gaming mice we have seen recently. Fortunately that did not turn out to be the case. These absolutely stellar performing earphones can be had for $249.99 which is a pretty good price for such a pair of in-ears.

The performance of these earphones is truly amazing. Even with only a single balanced armature these earphones definitely exceed the performance level of other earphones in the same price tier. That combined with the customizable sound signature and the exchangeable cable makes them a hard to beat.

These earphones exceeded my expectations in every way and provide a stunningly detailed sound that rivals the very best earphones on the market today. There is just no downside to these headphones expect maybe the price, but even that seems fair in comparison to what you get for your hard earned bucks.

Compared to a lot of high-end earphones that can deliver the same kind of performance these are actually a bargain and will be yours for a lot less money. Sleek-Audio's SA6 Earphones are way up there in the upper stratosphere of in-ear-monitors both in terms of shear performance and features.
