I've learned to come to terms with this mentality, mainly due to time constraints. Before, I would always do an insane amount of research and benchmarking to find the absolute best in its category, even for mundane things like a coffee grinder. I would aggregate thousands of reviews and turn them into sentiment analysis, cross-referencing reviews, and so on.

Now, I take a more 80/20 approach: I clearly define my needs and shut down any thoughts about features and capabilities that I don't need right now. Frankly, after years of thinking that I might use a feature later, I realise that I never do and never recover my investment in these kinds of gadgets.

Finding a trustworthy review source is key — by trustworthy, I mean mostly in line with your own standards. However, if you can try it yourself, that's always better.

For sound on small devices with clear voice and a good dynamic range, Samsung is quite good with its high-end Galaxy Tab line.
