Happy user of a Motorola S9 (but lost) for 7 years (2-3 week), I opted for this model despite the very mixed reviews. Compared S9, it is far behind + Wireless for 2 reasons: - The audio is objectively bad: "powerful bass" is written on the packaging, but that does nothing to apply these headphones. It's a huge disappointment! - The ergonomics of buttons is not very wise: when you press a button within firmly hold the earpiece, it heavily relies on its ear. Skip one track is inconvenient (no dedicated button). The S9 is better designed in that direction. - A battery life of 3 hours: it is what is advertised on the data sheet, and it's true. Tested on a marathon, unfortunately I run more than 3 hours. I think that a product of this type must take a minimum 4h for utiiisation for road race.
Positive points: Quick pairing nickel and held in the correct ear (consistent with the wearer of glasses that I am), small cable Comfortable final.
