Sport: fit - Sound: moderate

I have a pair of Sennheiser MX375 that really make the right bass and sound very nice voluminous, the high tones are only minimally accented (far more than bathtubs Loudness characteristic). And, although there are ear-buds, no in-ears.
For jogging, they are only partly suitable: unsecured they fall out, they must always cumbersome fixed-taping.

Therefore, the attempt with Sennheiser MX685. Well, they hold up well, although my ears are rather small and seemingly somewhat atypically shaped (in-ears do not go, not even with neckband).
Sonically they are very mediocre. I have on my Lumia 1520 rev bass neat and runterschrauben the heights strong, otherwise it is rattling metal. But with EQ goes.

Conclusion: with EQ on phone or player of the Sport for mechanical reasons probably the smartest alternative currently. Sonically for not so spoiled listeners or damaged inner ears no problem. For me as a hi-fi enthusiast just for organizations.
