Hello there, KevinLongtime,
Thank you for reaching out to the community, and sorry to hear about how you were woken up! That does sound like an unusual occurrence. We appreciate that you've shared this with us. As far as the volume lowering over time, it should not.
Let's make sure the Sleepbuds, app, and charging case are up-to-date. Please visit btu.bose.com to check the case for firmware updates.
If you notice the static again, we encourage you to contact our Sleepbuds Support team for further assistance. Here is their contact information: (800) 905-1273.
Let us know if there is anything you need!
Thank you again,
Mohsin - Community Support
I've had this happen three times.
The first time, after about 4 hours of sleeping with the Cascade sound, I woke up to the sound of loud static in my left ear. It was quite startling, and it sounded much louder than the safe 70 dBA max volume level that the Sleepbuds are supposed to be limited to. I opened the Bose Sleep app, clicked Pause, then clicked Play, and the problem went away. It definitely seemed to be a bug since the sound was suddenly different in the left bud, and the volume of the static seemed too high.
The second and third times, it happened in the same left Sleepbud, after about 7 hours of operation. Those times, the static noise did not persist - both times it just made 2 quick loud static noises, then the Cascade sound resumed.
I get this every night but I believe it is in both buds. I use Cascade. Stopping the sound in the app and restarting ALWAYS fixes it. I've also experienced volume decreases.
Soke to support, they are sending replacements and a return label and will give my buds to engineering to see if they can determine the cause.
Replacement arrived 2nd day air yesterday. Charged it up, updated the charging base, connected to app, did the firmware upgrade. What a difference. The sound was constant all last night. Did not go to a static like sound in the middle of the night, did not lower in volume. Did not seem to have a muddiness to sound that the original ones I purchased had. Hoping they stay this way. Just dropped off the defective ones at a UPS access point using the prepaid label Bose provided. I have to say Bose customer service is among the best I've experienced.
