appearance design
BeoPlay A 1 Bluetooth speaker adopts disc design, and B&; O also gave this product a nickname "Little Flying saucer", which is the most intuitive impression I saw this product. The size of BeoPlay A 1 is 133mm (diameter) x 48mm (thickness), while the weight is 600g. The light and compact body design also highlights the portable characteristics of this speaker, which can be easily used in your hand or put in your pocket or backpack for outdoor use. In terms of color, BeoPlay A 1 speakers currently have two color schemes: moss green and natural silver.
BeoPlay A 1 speakers look very smooth. It is designed with a circular anodized aluminum shell, and the B-amplifier part is made of polymer material. Metal and plastic are well integrated in one product, which can well protect the components inside the speaker, and also reflect the B&; O avant-garde design concept. BeoPlay A 1 does not have any prominent key and bracket design, and all keys are covered with rubber material on the base, which has anti-slip function and strong waterproof performance.
Key design
All buttons of BeoPlay A 1 are designed on the side of the speaker, including power button, volume adjustment button, connect button, Bluetooth switch and talk button. These buttons are designed by pressing, and the surfaces of the buttons are covered with rubber. But the experience in actual operation is not very good. If you put them flat on the table, it will be difficult to operate them with one hand. Maybe BeoPlay A 1 think more about outdoor use scenarios, and it will be easier to operate by hand. At the same time, the requirements of dust prevention and splash prevention are considered, which can adapt to more complicated use environment.
Battery design
BeoPlay A 1 has a built-in rechargeable lithium battery of 2200mAh, and its working life is related to its volume when used. In addition, this speaker also has adaptive power matching function to extend battery life. According to the estimation of actual use, it can play continuously for 6 to 7 hours under the normal speaker state. BeoPlay A 1 adopts Type-C USB charging interface, supports 2.5-hour 3A fast charging and hands-free call, and may be the mainstream interface of charging equipment in the future. There is also a 3.5mm audio interface near the power interface, which can connect a CD player and a DAP player. It has no Bluetooth transmission function and is suitable for more devices.
Product parameter
BeoPlay A 1 adopts standard bluetooth 4.2 and ADK4.0, which ensures good audio transmission effect. Using 2× 30W (D Class D) power amplifier module, the peak power can reach 2× 140W. At the same time, it is equipped with a 3.5-inch full-frequency unit and a 3/4-inch high-frequency unit, and the effective frequency range is 60-24000. BeoPlay A 1 speakers also support self-selection of EQ through BeoPlay application to adjust sound effects. In addition, BeoPlay A 1 also adopts a unique DSP algorithm and advanced high-slope filtering technology, which can form a 360-degree-wide sound scene, and can also collect sounds from all directions during voice calls, which can be used for small conference calls.
About sound quality
For music playback equipment, everyone is naturally most concerned about its performance in terms of sound quality. Although this BeoPlay A 1 is very small, it still performs very well in sound quality, and the volume is very full and rich, which is not weaker than some stereo speakers with high volume. At present, there are many Bluetooth speakers on the market, each with its own characteristics in sound quality. This BeoPlay A 1 pays more attention to sound balance, and does not particularly improve performance within a certain range. Listening to music as a whole is more natural and gives people a pleasant feeling. BeoPlay A 1 adopts the dual-unit structure of full range and treble, which also makes the sound of this speaker more penetrating, especially in the vocal part of the intermediate frequency, and the hearing of the high frequency and low frequency parts is very natural, similar to other B&; O speakers are very similar, and the sound is more natural and real.
The problem of insufficient low-frequency measurement that Bluetooth speakers have been criticized is not obvious in this speaker. The measurement of BeoPlay A 1 can meet the listening needs in indoor or outdoor small environments. It should be noted that the sound of BeoPlay A 1 placed on the desktop is different from that when it is lifted to face you. The former will be slightly thicker and the latter will be more transparent, so when a person listens, he can point the front of the speaker at himself, which will be better.
