With the soundcore collection, it seems for the vast majority, you can use just one earbud or earphone.
So whether the spirit (cheapest most basic) with neck band, or the expensive new earbuds (or cheaper life P2) you cannot to use just one.
The life P2, even registers both buds separately, so using Justine is ok… I donitnoften if late at night and want to listen to videos but not wake my fiancee, I’ll use just one bud.
With life P2 lasting 7hrs at a time, it should be.enough for a shift at work. I hrs is based on loud volume, so you MAY (no.otomises from me) find they lastn8 hrs on a quiet setting.
Plus being touch control, so easy to use subtley at work
