speaker.BH258Acan’tbepairedwithsmartphoneorothersimilardevices.
4.Forabettermusicquality,it’srecommendedtoselectheadphonesofasamemodelwhen
pairingBH258Atotwoheadphones.
5.TocompletetheBluetoothpairing,it’srecommendedtouseBH258Aintheplacewherethere
arefewobstructionsorotherBluetoothdevicesusing.
6.Ifthepairingfails,pleaseclearthepairinglistonBH258Aandsmartphonesetc.andtrypairing
again.Meanwhile,checkwhetherBH258AisinBluetoothpairingmode.Also,you’dbetterturn
offotherBluetoothdevices.
7.InRXmode,BH258Acannotsupporthands‐freecallingbecauseithasnomicfunction.
