As I like the comfort of lightweight in-ear headphones, I purchased the LG Tone Pro 750 to test. These headphones have a heavier part you wear around your neck, with the earbuds attached by short wires, so there is almost no weight at your ears. There are a number of different ear tips to get a comfortable and sound isolating fit.
Like the PowerBeats headphones reviewed earlier, These, too, easily connected to my phone by bluetooth. The headphones charge quickly, and have a 20+ day standby time. Although it takes a few seconds to properly insert the earbuds - they are comfortable once in use, and quickly removed if needed. The earbuds are kept in place on the neck strap by small magnets, so they are not dangling loosely,and susceptible to damage. I find these headphones very comfortable to wear, and easy to use when incoming calls occur, simply pressing a button to accept the call.
When first turned on, there is an announcement of the battery condition, and the connectivity status. Sound is clear, and the earbuds block a considerable amount of outside noise - almost as well as does my Etymotic hf2 headset. The neck surround portion is comfortable, though it might bounce around somewhat in certain activities such as running, and the sound isolation might be somewhat of a safety hazard if cycling.
These have become my first choice when heading out of the house, as they work as well in 'storage mode' when not in use as when they are. The compact holding of the earbuds being a major factor.
