Please some advise me to choose bluetooth headset

Focusing on battery life, i have the exact right choices for interviews and for using with only 1 ear.

1. Plantronics  M55 : this one can be considered a budget bluetooth ear piece. But what lacks in price, boosts up in battery life. At top volume, the battery lasts for about 8 hours and 28 minutes (top volume is really loud, and is not recommended for long use). At a moderate usage, this handset can reach about 11 hours of talk time. Also, to prevent the battery from discharging continuously, this earpiece features a DeepSleep mode which puts the headset to sleep when you are out of range from your paired device.

2. Plantronics Marque 2 M165 : this model has a smaller design, and it includes a secondary microphone for noise suppression with two additional eartip sizes. The battery life lasts for an average time of 8 hours on full usage. The good part about this model is that the charging time is very fast : 2 hours to be more exact.  

Today's bluetooth earpieces are designed with only 2 ideas in mind: battery life, and conversation quality. There is no need to opt for an expensive model. If you have a low budget, i would recommend these two above mentioned models.
