Uboom L Bluetooth Speaker, Wireless Speaker, JumboBass | 28W stereo sound, rich bass with 2 drivers, IP67 waterproof and dustproof, dual pairing, 16H, outdoor music box for party

Latency when watching video is too high, even with the video mode enabled.Sound is ok but not great. Low on bass and general crispness of the sound.Volume controls directly control your devices audio, which i dont like because i cant control the sound volume as finely as id like.Ok build quality, ok price.Got this one because reviews where good.I do not agree and will not get a second unit as planned to try the stereo function.

Great sound@great price!

Excellent speaker and for the price, you won't be disappointed in the slightest. The equaliser takes a little playing around with, to get the best solution for your own ear preferences and the specific situation/room/ambience you are using the speaker in. I have had it for about 1 week. It seems to hold all frequencies of sound and clarity of music/vocals extremely well over any volume from low to max. I have a few other speakers and I feel this trumps the other ones for all-round quality of sound and is much more attractively priced. Good bang for your buck. I like it that much, that I am going to buy a second one so that I can pair them. It doesn't have a powerbank (no biggy), but it has a built in mic which is amazingly helpful for taking calls handsfree and the other person can hear you very clearly. Can't comment on durability yet as I haven't dropped it, or had it playing outside in the heat for any length of time. However, it looks and feels like it is solidly and professionally constructed. You can hold it in your hand easily, it's not too heavy. However, it could do with a wriststrap just for added convenience. I prefer it in all respects (price, quality of sound, loudness, features) over my comparable market bracket JBL Flip 2 and JBL Charge 6 speakers.

El audio es muy bueno, se escucha mejor que otras bocinas del mismo precio. Lo mejor es que tiene aun entrada 3.5, la configuración de interior y exterior de Oluv's es una maravilla.

This is an excellent Bluetooth speaker if you are looking for a Bose-type replacement at a great price. I had the original generation Bose SoundLink, but it became a paperweight due to the battery no longer holding charge (and not working off a cable either). This Earfun UBoom L has a similar sound profile at lower volumes, offers great Bluetooth connectivity, and has clear, believable sound listening in small spaces or at low or moderate volumes.I'm not a sound engineer or audio expert, but from my interest in stereo and guitar equipment, I became aware of something called the Fletcher-Munson Effect. Basically, the human ear is more sensitive to mid-range frequencies (roughly between 2kHz and 5kHz). This means that lower volumes, the sound you are perceive will seem to have less bass than if the same EQ were applied at a louder volume. As a result, manufacturers of small-format speakers figured out that you need to boost certain frequencies at low volumes and generally reshape the EQ for your ears to perceive what would be a "flat" setting at a louder volume. Bose was a pioneer in popularizing this concept, but it's widely used in all types of affordable Bluetooth speakers, and the UBoom L is a great example of that.It sounds great out of the box, but with a phone app, you can apply special indoor and outdoor EQ settings from a sound engineer named "Oluv". If you're like me and frequently use Bluetooth speakers to play background music at very low volumes (while working, studying, or just for general ambience), then you'll appreciate this. There was a whole "Beats vs. Bose" thing about 15 years ago where people became obsessed with having as much bass as possible. Similar to a Bose unit, the UBoom L has plenty of low end, but with the Oluv EQ, it retains clarity and does not overwhelm the other frequencies. I will say that there is plenty of low end in this speaker, and there are presets and custom EQ's you can play with if you prefer a bassier sound.The internal battery charges with a USB-C cable, and I appreciated that they included an AUX jack. Some of these speakers are great to use with other audio equipment and instruments that either do not have Bluetooth, or would suffer from latency. There are plenty of great budget and premium Bluetooth speaker options nowadays, but this is a great all-around product.UPDATE (08/20/25): Need to make a slight correction to my review above - the UBoom L has a significant latency (audio delay between input and sound playing through speaker) when using the AUX 3.5mm jack. Apparently, this is a common issue not just with the Earfun units, specifically, but with most Bluetooth speakers that use any type of digital processing or EQ to produce sound. The latency is significant - around 250 milliseconds, I believe - which is far too large to use it effectively to play sound from any instrument. However, since this is a very "niche" use of this otherwise excellent Bluetooth speaker, I am not downgrading my review score.
