Does the Boostaroo improve sound quality?

It mainly raises volume. It is an analog amplifier without a DAC, so it will not clean up a noisy or low-quality source.

Can several people listen at once?

Yes. It has one 3.5mm input and three 3.5mm stereo outputs, so up to three pairs of headphones can share one device.

Will it drive high-impedance headphones?

Not well. Its 40 mW output suits typical earbuds and low-impedance headphones, but demanding models need a stronger amp.

It runs on AA batteries, so there is no charging cable or built-in battery to manage.

Does it work with a phone or tablet?

Yes, through the 3.5mm headphone jack. Devices without a headphone jack need an adapter.

The amplifier unit itself; check the listing for whether batteries are included.

Our take on the Boostaroo T613-BNC - Headphone amplifier

The Boostaroo T613-BNC is a battery-powered portable headphone amplifier that takes a 3.5mm input and splits it to three 3.5mm stereo outputs. It boosts volume up to about twice the source level, which helps quiet phones, tablets and in-flight audio reach a comfortable listening level. The three outputs let two or three people share one device, and the AA battery power keeps it free of a charging cable. It is a simple analog booster, not a DAC, so it does not improve a weak or noisy source; dedicated headphone amps with their own DACs offer cleaner sound and more headroom.
