I've seen a lot of fancy earbuds but the new ones from Sleek Audio are the first I have seen that can be customized to this extent. The new earphones from Sleek Audio can be personalized with interchangeable bass and treble ports, interchangeable multi-sized dual flange tips and interchangeable cables. The headphones can create your custom "audio fingerprint." The earphones can be work with the cord up or down. The headphones are available for pre-order for $229.99 and will be out in October.
