These days, I'm mostly riding solo and not doing group rides.
Last year, I won the DOSSA test and when I used it for a long-distance two-day group ride, the battery ran out, so I didn't have high expectations when I bought it.
I purchased it at the end of June this year and tested it once or twice before charging it fully.
In July, it hardly rained, so I rode about 40-50 minutes each way.
Listening to the radio on my phone while using it, I haven't charged it even once, and the battery still says "medium." If it says "battery low," I'm going to charge it.
I've been using it for a month without charging, and it lasts incredibly long.
By the way, I rode over 700km in July.
The mode I used is
not message mode but Bluetooth mode with the microphone off except when answering calls.
I didn't expect much from the sound quality for solo riding, but it's usable.
