The Good The tiny AmazonBasics Ultra-Portable Micro Bluetooth Speaker BTV4 bundles a discount price tag with adequate sound quality and an impressive 10-hour battery life.

The Bad The sound distorts at high volumes and the plastic exterior feels a little flimsy.

The Bottom Line Amazon offers an attractive deal with the budget-friendly BTV4 Bluetooth speaker, as long as you're comfortable sacrificing a bit of fidelity for price and portability.

Although it won't exactly shake your windows, the AmazonBasics Ultra-Portable Micro Bluetooth Speaker is a hot seller online thanks its budget price tag. For the uninitiated, AmazonBasics is the company's generic in-house brand that bypasses the middleman and pushes cost savings to the customer. This BTV4 "Micro" model is the smallest of the speaker line, followed by the BTV2 and the larger BTV1 .

The BTV4 is regularly $25 but discounted to $20 right now on Amazon (£18.49 in the UK), which is about the cheapest we've seen for a wireless speaker, even less than the Cambridge SoundWorks Oontz Curve and the Philips BT2500B that both sell for $10 more.

The size and shape of the BTV4 bears resemblance to a hockey puck, but it's significantly lighter at 0.25 pounds so you can easily travel with it in your pocket or purse. While in transit, you can use the supplied felt carrying case to protect the plastic exterior (available in black, blue, red, white and grey) from scratches.

The build quality is what I expect for $20 -- the plastic has a notable flex to it and although I can't officially speak to its long-term durability, it's safe to assume that this won't survive a ton of abuse.

The speaker is designed to sit facing up and a black plastic grille on top protects the single 3-watt speaker inside. The bottom of the BTV4 has a ring of sticky rubber that prevents it from scooting around on a table while eliminating sonic vibrations.
