・I bought these last summer for outings and used them for about 4 months (about 3 times a month), so they are almost as good as new, and the battery condition is also good. ・Even with strong bass, the high frequencies are not compromised, and the sound is very clear. ・The battery lasts up to 15 hours. ・They are waterproof, so they are perfect for workouts. ・You can easily connect and adjust the sound quality using the "Bose" app. ・Normally, when walking, the vibrations from your steps are transmitted to the earphones, making it difficult to hear the sound, but thanks to Bose's unique design, you can hear the sound very clearly even while walking or running. #bose #ボーズ (Bose) #ブルートゥース (Bluetooth) #Bluetooth #ブルートゥースイヤホン (Bluetooth Earphones) #Bluetoothイヤホン (Bluetooth Earphones) #ワイヤレスイヤホン (Wireless Earphones) #BoseSportEarbuds #SportEarbuds #Earbuds
