I have bought NGEarsage 1.0 and support team has upgraded to NGearsafe 2.0 for trial.
Listening - Excellent clarity to listen other persons voice with crisp and laud.
nearby person could not hear speaker sound so privacy is maintained.
Mic- great clarity for vocals to person hearing on other side. Noice cancellation work perfect.
Battery - last for long time... do not understood continuous talk time because i charge it after 5-6 Hrs. i have frequent meeting for at least around 6hrs a day.
Comfort - Open rear design is highly recommended for people having frequent meetings. Do not found any issue with design. it has highly confirmable to listen.
Connectivity - i can use this 50 feet's without noise without walls barriers.
Issues - small software bugs like - (1)voice breakage in first call so we have to turn of laptop Bluetooth and turn on once so issue gets resolved. (2) Voice goes to max for first call automatically. (3) carrying headphone without any solid box may damage so good compact case from Ngear should be given instead of bag.
Overall - highly recommended to buy due to comfort & convenience.
