Maybe it’s out of spec, but my little cassette boombox with Bluetooth outperforms every other device I’ve used. Instant pairing. Multiple devices. Unwavering signal. Only the speakers and driver circuit let me down. It’s tinny and quiet, even at full volume with tone knob adjustments. Still, it’s a sure thing as far as connection goes.
