In fact, the static noise reduction effect of freebuds3 is really quite good for semi-in-ear headphones, which can basically shield the sound of air conditioning operation in the air-conditioned room. In the case of wearing headphones most of the time for noise reduction, the charging box can be used for one day, the comfort is good, the cost performance is very high, and the noise reduction comparison with boseqc20 will have a little gap. But it's not noticeable in the air-conditioned room.
It's just that the noise reduction will be turned off once freebuds3 is up and running, which will hopefully be fixed later with an update
