Unboxing and First Impressions
The EarFun UBoom L arrived in a compact box. Inside, I found the speaker itself, a USB-C charging cable, and the usual documentation. Notably absent was a wall adapter, but EarFun states that the speaker is compatible with most standard 5V/3A phone chargers.
The UBoom L's design is understated, featuring a sleek black chassis with a speaker grill covering most surfaces. The Irvan logo sits prominently on the front. Its compact size and lightweight build make it exceptionally portable.
The top panel houses the intuitive control buttons: power, Bluetooth pairing, volume controls, play/pause, and sound mode selection. Indicator lights provide clear feedback on power, Bluetooth status, battery level, and active sound mode.
Sound Quality and Features
The UBoom L boasts impressive audio capabilities for its size and price point. Dual 55mm full-range drivers deliver a surprisingly rich sound profile with solid bass, clear mids, and crisp highs. The bass is deep and well-defined, adding punch to the overall listening experience.
One notable feature is the customizable sound mode. Switching between indoor and outdoor presets allows you to tailor the audio to different environments, compensating for various acoustics. The sound quality is consistently excellent, with only slight alterations in the sound profile at the maximum volume setting.
Beyond its core audio performance, the UBoom L offers Bluetooth 5.0 connectivity, a TWS (True Wireless Stereo) pairing feature for broader sound staging, and a 3.5mm aux input for wired connections. It also boasts IP67 water and dust resistance, making it ideal for outdoor use.
Battery Life and Additional Features
In my testing, the UBoom L's 5200mAh battery lasted approximately 9 hours and 20 minutes at 50% volume with AAC codec, falling slightly short of the advertised 16 hours. Charging time using a 5V/3A charger was 3 hours and 12 minutes, quicker than expected.
The EarFun UBoom L also has a video mode to reduce latency (from 250ms to 150ms), making it ideal for watching videos. This mode can be activated via the Bluetooth button. However, remember the Bluetooth range is reduced in video mode.
The accompanying EarFun Audio app offers a plethora of customization features. This includes a graphical equalizer with multiple presets, a custom equalizer function, and a variety of helpful controls.
Other EarFun UBoom Models and Conclusion
The EarFun UBoom line also includes other models, such as the UBoom 360 (360-degree sound, IPX7 rating), UBoom Raver (karaoke functionality, RGB lighting), and UBoom X (four drivers, louder output). Each offers a unique feature set to cater to diverse needs and budgets.
The EarFun UBoom L is a compelling portable Bluetooth speaker, particularly at its price point. While the battery life didn't fully meet expectations, its sound quality, versatile features (including the TWS and aux input), and robust build make it a worthwhile investment. It excels as a compact everyday speaker, particularly when used for media playback.
For those seeking a compact yet powerful speaker with excellent sound quality, a wide range of features, and rugged durability, the EarFun UBoom L is a highly recommended choice. Its versatile design and adaptability make it a versatile solution for many audio needs.
