EU is a world-famous brand of high-end moving iron technology earphones, and is known as the four major manufacturers of moving iron earbuds along with Intermei, Weston and Shure, and is well-known in the field of professional-grade monitor headphones. After EU was acquired by Logitech, the product line was fully expanded, and in 2011, it officially entered the Chinese market, and the world's first EU headset custom retail store was opened in Shanghai Grand Gateway Plaza, and the wireless portable speaker product line was released at the same time.
 
For now,EUThe focus of products is still in the headphone business,There are only three Bluetooth speakers,But it is highly recognizable in the market,The cross-shaped logo erected on the front contrasts with the fuselage,It is both low-key and full of youthful atmosphere。 Because EU focuses on the outdoors, although the body is made of plastic, the workmanship is quite exquisite. All models support IPX7 waterproof rating and can be immersed in 1 meter of water for 30 minutes. Both the MEGABOOM and BOOM 2 feature dual windproof microphones for hands-free calls, while the WONDERBOOM can only be used for music playback.
 
Voted the best pool party speaker by PCMAG, the MEGABOOM features two 2-inch drivers and two 2x4-inch radiators for a very loud volume. The 1299 yuan BOOM 2 can be described as a smaller version of the MEGABOOM, but the performance is slightly weaker, in comparison, the MEGABOOM that costs 100 yuan more is worth buying.
 
Sound quality deficiencies are the biggest factor that EU can't compete with other brands, and in Consumer Reports, EU has the WONDERBOOM and BOOM 2 at the lower ranking. They are generally reflected that the three tones have weak points, and the stereo sound cannot be heard at a distance from the speaker, as if it is a mono speaker.
 
But the sound quality of portable Bluetooth speakers has never been comparable with home speakers,If you only consider the characteristics of outdoor portable sports,EU's speaker performance is acceptable,But the sound quality is only at an adequate level,Comprehensive strength is average。
 
值得一提的是，EU ROLL 2曾是the wirecutter推荐的“最佳蓝牙Speakers”，但由于产品推出年限已久，目前中国市场中并无此型号出售，需通过海淘购买，其整体表现已不如同体积的B&O A1，而且依然具有音质缺陷，因此不在该品牌中作为推荐型号。
