Am highly satisfied with the wearing comfort and sound quality. Listening to music with the iPad is a delight, a very balanced sound. The bass get along well with the middle or even better with the great Earbuds. Since the ambient field is Allerding sounds moderately totally excluded, one hears nothing more from the environment. On the road, but I would prefer to give up rich bass and in favor of road safety (as a pedestrian, of course) "raise" the small earbuds. The voice quality is very good in both directions.
The farther advantages with the mobile app are speed dial memory of phone numbers on the right Jog switch available, I use from the first minute. Reads out text messages with the APP Tone & Talk also works well and is helpful.
Am completely satisfied with the LG-HBD-900, the part does what it should and to my complete satisfaction, I would the device to others.
