Archeer A210 Bluetooth Speaker Review: DESIGN and FEATURES

IMG_7508
The Archeer speaker is mainly designed for outdoor use as it has IP44 rating meaning that it can survive water sprays from all directions and some minor drops.

It is made of rubberised plastic and it has multi-directional speakers meaning that the sound is coming out from all directions. Also, the device is really compact and portable, so you can simply drop it the bag.

On one side you have a flap and underneath it you can find your micro USB charging port, AUX input for non-Bluetooth devices and microSD card slot as this speaker supports playback directly from the memory cards. All you have to do is to insert the card and the music starts playing automatically.

On the other side you can find a really interesting volume rocker. You have to spin it a lot to adjust the volume and while it may be annoying for some, it is pretty fun to me. Also, the volume rocker doubles as play/pause button if you press it.

On the front there are skip tracks buttons, battery capacity indicator, which is actually a really neat feature, power on/off switch or mode button and a few notification LEDs. 

Archeer A210 Bluetooth Speaker Review: SOUND QUALITY

IMG_7491
You can listen to music either via Bluetooth from your phone or directly from the microSD card. The sound quality… it’s really good. To be honest, not all manufacturers succeed when trying to make a good sounding multi-directional speaker but Archeer did a pretty good job.

The sound is deep and clear, and I could hear a pretty good balance between lows, mids and highs. 
Finally, this thing is loud for its size as it has 10w of total volume output and the bass is really punchy.

As for battery, the speaker sports a 1500mAh unit and I could get over 10 hours of continuous playback, which is a great result. As far as Bluetooth, I didn’t have any connection or range issues.

Archeer A210 Bluetooth Speaker Review: CONCLUSIONS

IMG_7479
The Archeer A210 Bluetooth speaker costs $39 and I believe it is a pretty good offering considering the feature set it has. 
The speaker sports a great build quality, it is splash-proof, shockproof and dust-proof, it has a lot of controls and indication LED lights, it supports the playback from the microSD cards, the battery life is great and the sound quality is really good.

However, a few shortcomings would be that the call quality is bad and it even has connection issues. Also, the flap that is covering the ports could stay more firmly as I always have to double check it before using it in the rain or shower.

Although it may not not be the only option available on the market, it can be definitely recommended.
