What Do People Say About the Bose 251 Environmental Speakers?



The 251 environmental outdoor speakers received an excellent rating on Amazon.

A buyer from the United States, said “The sound is terrific!… Once installed, playing the speakers via a Bluetooth connection is a breeze.”

The same Amazon user, however, cautions potential buyers not to be misled by the term “wireless” as there are wires that you still have to connect. “You have to connect the speakers to an amplifier via speaker wire and plug in the amp to an electrical outlet,” the Amazon user added.

Another customer shares that at first, he did not know how many outdoor speakers he would order because he had a relatively large outdoor entertainment area plus they have a pool area.

So, he ordered 4 Bose outdoor speakers. “When I cranked the 4 speakers, the sound was too loud, I have 3 acres of property. The 2 speakers deliver top-notch sound,” he added.


ShoopkoTube conducted a sound test on Bose 251 and said that he did not even put on the max volume yet. 

When a Youtube user commented on the video saying, “In my simple opinion, they work fine and sound great ” ShoopkoTube replied, “totally agree! and they all look great, talkin’ about the design.

Bottomline: Should You Buy It?


As audio enthusiasts, we definitely recommend these speakers. The speaker set has a durable polypropylene cabinet that can withstand extreme weather conditions for long-lasting outdoor sound performance.

It also has a decent stereo sound and you can even combine these speakers with SoundTouch system or Lifestyle SoundTouch entertainment or home theater system outdoors or second room.

The two full-range drivers positioned in the speaker design further offer lifelike sound even in a wide listening area, compared to conventional outside speakers that only deliver sound in certain “sweet spots” and not around the patio, yard, or pool area.
