Logitech UE MegaBoom: UE Megaboom will not charge (light still flashing)

Sat, 14 Mar 2026 23:31:36 -0700

I haven't used the Megaboom for 6 months, took it out of storage and used it for the last couple of days while I was working outside (still had battery that lasted two days). Once it went flat, I plugged it in to charge overnight, the white light was flashing as normal. In the morning, I tried to turn it on and it said "Critical battery, please charge". While charging, if I try to turn it on, it just says "Charging, please wait". It still won't work no matter how long I leave it charging, though the white light is still flashing as normal. Is the battery toast? I did use it outside on a day with a lot of fog

UE BOOM 2: Speaker says it's connected but sound won't play through the speaker

Sat, 31 Aug 2024 00:46:00 -0700

My speaker is fully charged, the name shows up in my iPhone, and it says it's connected. But when I go to play music or videos, the sound comes out of my iPhone. I checked 'devices available' on my Spotify app and the UE boom doesn't show up. I'm not sure what to do??

Logitech UE Boom: No sound from the device at all.

Mon, 19 Aug 2024 03:31:48 -0700

When I turn it on or off, it doesn’t make any sound. The speaker worked just fine about a week ago and I haven’t used it since then. I have factory reset it and updated it. It does connect to my phone but there still isn’t any sound.

Is there any way to turn down or turn off the start up sound on the UE Wonder boom. It is really annoying when everyone around you always comments ‘What was that?” everytime you turn on the device in the office.

Logitech UE Boom: Battery is dying very quickly!

Sat, 21 Sep 2024 20:11:49 -0700

I got the UE Boom 2 for Christmas and it’s supposed to last a decent amount of time...like 12 hours or so. I understand at high volunes this time goes down but mine is lasting maybe 2 hours or so and I already sent one back because of this but I’m having the same problem with the 2nd one!!!! I usually charge it at night while I am sleeping, is that the problem? Am I over-charging it??

UE Boom 2: Sound Delay after firmware upgrade to 2.0.97

Sat, 18 Jul 2020 22:28:01 -0700

This seems to be a very common problem, looking into the logitech forum thread here and is seemingly also affecting the original UE Boom:

https://community.logitech.com/s/questio...

After updating the speaker to the current firmware version of 2.0.97 the speaker has a delay of about half a second in sound playback. This is not an issue while playing music, but in the case of videos it is quite upsetting. The issue persists on all available devices to me, testing different video players, games, etc. The delay is present no matter what.

I honestly hope that UE / Logitech will fix the problem soon, but I am not sure when this is going to happen. Because of this, I am posting my problem here in the hope to find someone with a solution or temporary workaround.

Note that it is seemingly not possible to revert the firmware, what would be the easiest fix. Also a reset of the speaker has no effect on the problem.

I thank you in advance and would be delighted to get a suitable solution!

Hey,

I never received an answer from Logitech / UE regarding the issue...

Haven't installed the update yet, but if it fixes something for me I'll let you know.

In the official thread of the Logitech forum, reseting the UE Boom by holding the minus button and power on for approx. 10 seconds, fixed the issue for some people. This was no fix for me, but maybe after the update... Hope still remains.

Cheers Muppel

UE Wonderboom: Speaker turning itself off

I just got a new UE wonderboom speaker off of Amazon, fully charged it, and now when I try to play music through it it will turn itself off after playing for a few seconds. I’ve tried a default reset and removing the device from my phone, any ideas on what to do?

UE Wonderboom: Why are none of the buttons working on my wonderboom?

Wed, 25 Jun 2025 15:28:39 -0700

I’ve tried pressing every button on my spreaker and none of them are doing anything, I can’t even turn it off. I tried to reset it five times but it doesn’t seem to fix the problem. It only turns on after a long charge and then immediately after, all the buttons are useless still.

Buttons that don’t work (all of them):

UE button
Power button
Pairing button
Volume + button
Volume — button

UE BOOM 2: UE Boom 2 remote power not working

Mon, 09 Dec 2019 11:25:44 -0700

Hi,

I am using the boom 2 via my iPhone 6s so I have Bluetooth 4.0 support. Yet somehow the remote power on function does not seem to work. I can switch my boom 2 off but when I want to turn it back on again via the app it just gives a standard instruction on how to connect your phone to boom 2.

The remote power function in the setting is turned on by the way.

Any thoughts?

UE BOOM 2: Factory Reset won't work...

Sat, 08 Nov 2025 22:44:21 -0700

This is quoted from another post:

Factory rest [for UE Boom 2]

Note that doing this many times in a row may harm your speaker, so refrain from doing this more than once or twice.

What does this mean exactly? I have tried resetting my UE Boom 2 and now the Bluetooth Sync light won't stop flashing when I try to turn it on. And it won't display on any devices either. Is this speaker toast? Thanks.

Logitech UE MegaBoom: Stuck in Demo Mode

Fri, 19 Sep 2025 08:47:12 -0700

I have a UE megaboom.

It is a “demo” model and hence has bluetooth disabled.

I have tried factory reset (Minus, and power button for 15 secs)

I have tried hard reset (Minus,Plus, pairing button for 15 secs)

When I try to update software with the UE speaker update assistant on windows, Windows cannot detect my device - “USB device not recognized”, and then the update assistant cannot proceed.

Logitech UE MegaBoom: No flashing Light when charging

Sat, 04 Jan 2025 16:07:45 -0700

Hi there! I have the UE Megaboom and it doesn't charge at all. Currently, it only turns on when it is connected via charger. Whenever i turn it on when its connected, and press the + and - buttons simultaneously to check the charge, it keeps saying its 40%. Also the charger LED does not turn on at all when connected. I know the LED itself is not blown as it was charging after some fluke but now its back to being turned off. I have tried the following:

1. pressing all combinations of the buttons (i.e. bluetooth, power, + and - in pairs, triples or all 4), (power&- for 10s resets after sound but still cant turn on without charger)

2. Trying a new battery. (When there was no battery connected in the speaker and it was also connected by a charger, the LED light was flashing but when the battery was connected it stopped working once again) This is the battery replacement i used:

https://www.ebay.com.au/itm/3400mAh-25-1...

3. Repeatedly plug and unplug charger for short cycles ~5s(charger connected)/~2s (charged disconnected) for 5-10mins and then leaving to charge for many minutes.

I have access to 2 chargers on which is quick charger QC 3.0 with 5V & 3A and laptop charger with 5.1V * 1A. I had brief progress today when i did step 3. with the QC 3.0 charger and then connecting the megaboom to the laptop charger after all those cycles. It then momentarily lit up the white charger light for 2-5s but then turned off.

Im running firmware version 2.2.9.

Any help will be appreciated.

P.S: I can’t avail my warranty as it’s past it. I already contacted Logitech recently and they said since i replaced the battery they wouldn’t give me any support.
