I personally have a 10×50 model pocket sized but some unknown company years ago. Did some research for a new one recently. I’d suggest not to spend too much time on reading into all the details, its never ending 😅 So here’s a summary…
The main criteria to consider for your specific needs are:
Important thing to note is to understand the numbers
Model numbers on binoculars essentially tell you their
– strength (magnification power)
– size (objective lens diameter).
In 8×42 binoculars, for example, “8” is the magnification power and “42” is the diameter (in millimeters) of the objective lenses (the lenses closest to the object you’re viewing)~ Rei Learn – Expert Advice on Binoculars
Which is better 10X50 binoculars vs 10X42 binoculars?
The 10X50 has bigger objective lenses, and does a little better for brightness and focus around the edges. The 10X42 may have better focus at the center, Advantage: 10X50 – albeit you’ll only see that advantage in low light conditions, like early morning or early evening.
One good friend Deepa Mohan, an avid birder among a long list like naturalist, writer, musician etc… posted this recommendation:

Apart from that, maybe one of the following can also be considered, depending on one’s budget. You can check out a few reviews, though with some budget on the time!
The next level zoom will need a tripod, or even if younger kids are trying to use this. The advantage of the 15×70 is one may try star gazing as well.
