Here I would like to say, why does this audio power supply standard not use the standard Micro USB interface, why not use the standard 5V input voltage, so even if manufacturers do not prepare the power adapter and charging cable, the audio can still be charged.
In addition, with Beckham HiFi Bluetooth audio attached warranty card, manual, contact card, AUX audio cable, things are quite complete, the only regret is that the audio cable length is 60cm, personal feeling is still a bit short, suitable for a limited range of application scenarios For example, a wall-mounted TV is almost impossible to connect this Bluetooth audio with this AUX audio cable.
Product charging
Beckham HiFi Bluetooth audio built-in 2 2200mAh lithium battery, maximum volume playback life time of 3.5 hours, 50% volume playback life time of 8 hours. The power supply standard is 9V/2A, and the built-in battery for Bluetooth audio can only use a dedicated power adapter. Therefore, I recommend that the power supply standard for this product be designed as an ordinary, standard USB Micro USB 5V that can be sourced locally. 2A charging standard, so that even if the original power adapter is broken, you can use other power adapters to power it.
The Bluetooth audio is charged, the next power indicator is on, and the blue light shows, if the built-in 2 2200mAh lithium battery is full, the indicator light is white, the whole operation process is very simple, and the power supply is not at the same time Affect our normal use Beckham HiFi Bluetooth stereo.

Audio audition
The brand new unopened audio system requires a chance to listen to the feelings of a few days, the sound quality is pure and no noise, high-pitched sound, bass shock, mute noise is still there, with my family's hundred-dollar Edifier audio noise floor In contrast, the noise of the walker's sound is smaller than that of the Beckham HiFi Bluetooth, but it can also be heard. This is a common problem of all sounds and cannot be eliminated. It can only be reduced.
Listen to a "Go to the End of the World" of Dyangyang Dolma, the melody is high, the voice is bright, and the high-pitched sound is clear without breaking the sound. The high resolution of the chip will make the sound a true reduction.
Listen to "Little Apple". This classic old song has a unique tone, a smooth midrange, strong bass, a strong sense of rhythm, and a strong appeal and call-to-action.
After listening to the legendary free flight of the Phoenix, the song incorporates the elements of some folk music. Coupled with deep emotions and voices with ethnic emphasis, it will be full of the romantic feelings of the vast grasslands, the treble will be bright, and the bass will have a strong sense of rhythm. Do not drag and drop.
At the same time, the author uses the wireless Bluetooth connection of the mobile phone to perform the audition. The effect is as above. Beckham HiFi Bluetooth audio Bluetooth effective connection distance is 10 meters, the specific connection effect varies according to the actual scene, so use wireless Bluetooth connection, in order to ensure high-quality playback, try to avoid long-distance, obstacles or the same frequency Connect in the case of a working device. I use the Bluetooth connection to play the same effect as the AUX audio cable connection. The only difference is that the Bluetooth connection is affected by the environment, which is likely to cause Caton's phenomenon and reduce the user's listening performance.
