EarFun UBOOM Review

Choosing the best portable Bluetooth speaker to spend your money on can be a daunting task with so many brands and options available. It’s very simple to be seduced by well-known brands like JBL or Bose and spend far more money than is necessary. Being a relatively new company, EarFun’s most recent product, the EarFun UBOOM 360 speaker, is proof that sometimes less well-known brands can offer excellent value.

The portable Bluetooth speaker provides a rich, clear audio experience with lots of bass. The UBOOM, which costs around $50, has a wide range of features that are typically unheard of in this price range and boast qualities typically found in much larger systems. You might be in the market for the wireless and waterproof EarFun UBOOM 360 speaker.

The EarFun UBOOM has a height of 6.5 inches, a width of 3.5 inches, and a weight of about 20 ounces. Beats on the go are made possible by their small size and ease of storage in your backpack, car cup holder, or drink holder on a bicycle. Additionally, the speaker has an IPX7 protection rating, which means that should it accidentally fall into the pool, it can withstand rain, spills, and submersion. This entails that you can take the speaker with you wherever you go, including the beach, the shower, and other public spaces.


The speaker has a mesh-like Kevlar texture that feels sturdy in your hand and a cone-like shape that fits comfortably in your hand. A circular grip pad at the base ensures that the UBOOM stays put when placed on any surface. High-volume bass vibrations are mellowed by the textured rubber base, which also offers good surface contact. The controls are located on the top of the speaker, which has a matte finish that is also fingerprint-friendly.


Each button has a squishy texture that ends in a click, and they don’t seem to be going out of style anytime soon. The UBOOM has a multi-function button underneath, volume controls, a sound-mode button for Bluetooth pairing, and a power button in the center. You will be able to do things like pause and play music, tap twice to move forward and tap three times to go back. Siri, Google, or Alexa can all be accessed by holding down the multi-function button for one second.

The port covers on the majority of Bluetooth speakers with high IPX water resistance levels are typically so tight that attempting to remove them could result in breaking a nail. The EarFun UBOOM has a great covert feature for women because it offers an airtight, secure close but opens with ease.

When the port cover is opened, a Type-C USB charging port and a 3.5mm AUX input for wired connections are visible. The portability of a Bluetooth speaker is one of its main benefits, but there are times when having a wired connection option via the auxiliary connector is preferable. In many cases, a wired connection is advantageous for preserving battery life and, in some cases, for producing better audio quality.

EarFun UBOOM Buttons


  • Excellent bass with no distortion that thumps and flows smoothly.
  • Two settings for indoor and outdoor use let you adjust the sound to the environment.
  • You can take your device from the shower to the beach with the IPX 7 rating and prevent it from accidentally submerging in water.
  • Parties benefit greatly from the 360-degree design because the sound fills the entire space.
  • Exceptional battery life—up to 16 hours, depending on volume—and quick charging—4 hours.
  • Bass-absorbing textured rubber bass and high-quality build with fingerprint-friendly buttons and easily accessible ports.
  • a multi-purpose button that can connect to Alexa, Siri, and Google.
  • For an even more immersive experience, pair the product with another EarFun UBOOM since it is True Wireless Stereo.
  • voice microphone built-in for hands-free calls.


  • When using an aux cable to listen, waterproofing is ineffective.
  • If your paired device is in a different room, the Bluetooth connection may slack slightly through several walls.


Stereo pairing

The inclusion of True Wireless Stereo, which enables the use of a single device that can be connected to two UBOOM speakers configured as left and right channels, is one of the more pricey features found in the EarFun UBOOM. For those on a tight budget, this feature is optional and probably not necessary, but after hearing the sound quality from just one speaker, you might be persuaded to start saving and buy another UBOOM in the future.

USB-C and Bluetooth 5.0

Numerous speakers are still produced with Bluetooth 4.0 and antiquated micro USB ports. The UBOOM has Type-C USB and Bluetooth version 5.0, which is significantly better than its forerunners. EarFun is the new kid on the block looking to make some waves in the industry. A portable speaker’s battery life is a crucial component, and this one has a rechargeable 4400 mAH battery built right in. While Bluetooth 5.0 offers better audio without delays and supports connectivity over distances of up to 100 feet, Type-C USB ensures optimum charging speeds in under 4 hours for a startling 16 hours of playtime.

Sound and Performance

The EarFun UBOOM offers two different play modes, making it a great value. The “mountain peak” button lets you choose between indoor and outdoor modes. This makes the UBOOM ideal for anywhere because it improves bass indoors or raises volume outside. Don’t give up, bass lovers; the dual-passive bass radiator design ensures that the bass still thumps loudly in both modes. Considering that drivers are the core of any audio device, choosing one with a suitable size is crucial.

The number of drivers and their placement will affect the speaker’s ability to be placed and how it sounds. The UBOOM has a twin-driver setup, which will be noticeably louder and comparable to larger speakers. Most small speakers have a single, full-range driver that angles either upwards or downwards to better displace sound. Two 45mm transducers and two 12W drivers are actually included in the 360-degree speaker, which provides window-rattling bass for EDM and clear audio for rock and classical music.

Because of the speaker’s 360-degree design, you can put it in the middle of the room and everyone will hear the same thing. With one exception, the mid and high ranges are well-represented. DSP technology has also been used to improve sound, giving the impression that it is incredibly clear, crisp, and distortion-free.

As was already mentioned, the UBOOM has Bluetooth version 5, so you should be able to move up to 100 feet away from your speaker and still hear it clearly and continuously. The UBOOM can actually produce a deep and immersive stereo sound in every direction for its 6.5-inch height and 3.5-inch width size, which is unheard of in most devices in this dimension and price range.

What You Will Recieve

EarFun UBOOM Conclusion

A skilled team of acoustic engineers, industrial engineers, and music lovers founded EarFun in 2018 with the goal of developing the next generation of wireless audio devices. With products like the EarFun UBOOM 360, it is evident that they are not far off. It would be absurdly difficult to find a better Bluetooth speaker for under $100 with features like deep bass audio quality, an incredibly sturdy build, Bluetooth 5.0, Type-C USB, 16 hours of battery life, and an IPX7 full waterproof rating. The EarFun UBOOM might be the perfect speaker for those on a tight budget who want a device that can do it all.
