I had a pair of the wireless buds without the neck wire but lost them, so I purchased this version hoping I could hang around my neck when not in use. Fazit: Wer draußen angeben möchte mit Markennamen, wem Qualitätsunterschiede zu anderen Hörern nicht so wichtig sind, wer nur im stillen Kämmerlein Musik hören möchte, und für den Geld keine Rolle spielt (kurz: Wer die neuen feinen Kleider des Kaisers unbedingt sehen und bewundern möchte), der sollte hier zugreifen. This is exceeding expectations so far! In my experience the wide sketchers run slightly longer as well as wider and for her the 9. The 2nd one had issues where the middle mouse/wheel key has spotty registration. They have the comfort of high end but cost of mid grade brand names. 5mm cables lying around and would like to keep those in different places for convenient use with my headphones. I can also get the headphones in quite comfortably without having to retract the headband so its great for real world ease of use. I can hear the person clearly and so can they, it also filters out the background noise around me very well for whoever I am talking to. VERDICT: If sound quality is the most important factor, then the Bose are not in the running as far as Bluetooth performance is concerned: the other two are a significant notch above.
