... An exceptionally high robustness of the cable; even with very strong bending, rolling, pressing, drawing, etc. It came with me to any interruption or disruption of playback quality; the para-aramid reinforced cable provides excellent strength and reliability
... An unconditional resistance to water; even in heavy sweat flow and / or exposure to rain, the headphones were fully operational and unaffected even in the reproduction quality
... A very easy cleaning and maintenance; the antibacterial ear adapters (SteriTouch) glued little, can easily be rinsed off with cold water when needed and is not porous even after frequent use
... A reasonable sound quality at low or middle tones and a rather low bass strength; I would in any case not hear electric music at the highest volume since the headset filters only moderately
Unfortunately, the Sennheiser MX 686G sport earphones also has a few quirks. Particularly ...
... Keep the peg despite the adjustable mount to my ears not fixed; the outdoor use with strong head movements the plugs slips when me regularly from the ears; then use usually alternatives with bracket
... The sound quality is really clouded with improper maintenance; it sounds then partly tinny and overexcited in the depths
For me, above all, from the design a good companion for easy indoor exercises such as rowing machine.
