Parents need such a portable speaker: JBL SD-12 portable card speaker measurement

Many people who buy gifts for their parents have this problem:

Parents always say that there is no shortage of anything, plus they are usually not by their side, they don’t know what to buy, they are worried that they don’t use it if they buy it, and they are idle and wasteful.

At this time, as long as you live with them for a few days, you can find that they are not as rich as they say.

A colleague said that when he went home, he saw his father listening to the loud and harsh stereo, coupled with his old age and poor sleep, he woke up at 4-5 o’clock in the morning. When I wake up, I like to turn on the stereo to listen to the opera, over and over again, boring and harsh, listening to it is uncomfortable, the key is that he himself still feels that the sound is quite loud, very durable, and quickly went to buy a JBL brand speaker, multi-functional and ultra-portable. Specifically to suit his preferences, he downloaded hundreds of opera programs and inserted the card to listen to them as he pleased.

Another colleague said that when she was a child, her grandmother liked to listen to the radio to do housework, listening to some life programs, news, using more than ten years ago, grandpa bought a Sanyo large radio, like a shoe box as big, the sound is very low, plugged in the power is not portable, now can only receive 2 ~ 3 programs, but the signal is not bad, occasionally failure grandma will shoot a few times, looking at the mottled appearance, but also for grandma to go out to listen conveniently, she bought a JBL very practical portable multi-function card speaker on the Internet. It is small, but the signal is stable and the program is rich.

These are small details that the elders won’t say or ask you to do, but as long as we are willing to take the time and dedicate ourselves to buying practical gifts for our families.
