Thanks for using my B&H links or Amazon links to buy (B&H Photo preferred, and the B&H Payboo card can save you a good bit of money by paying the sales tax).
The end of the year is nearly here—see my post on Section 179 business tax deductions. Equipment must be *put into service* by year end in order to qualify, not just ordered.
BIG WIN / HUGE VALUE: Sony WH-1000XM4 noise canceling headphones
Noise cancellation is something I make use of every day as a core health requirement*, and rarely have I gotten so much value for my money, in terms of usage time and performance—top of my list for useful brain-saving stuff are the *on sale* Sony WH-1000XM4 noise-canceling headphones (Sony WH-1000XMM4) @AMAZON, which also make excellent headphones for music and podcasts.
Why pay double the price for the unproven and way-too-heavy Apple Airpods Max or the inferior earbud options when the Sony headphones are widely acknowledged to be the best on the market?
I also own the Sony WF-1000XM3 True Wireless Noise-Canceling In-Ear Earphones, but they were a waste of money for me: they never fit my ear canals well, falling out constantly, making them useless for most anything but sitting in a chair. So I rarely use use them. No earbud can ever compete with a good over-ear headphone, just by the fact of sealing off the ear by a good amount, even if not turned on.
* Having always been noise-sensitive, post-concussion it is more acute, though I have improved greatly over the initial year.
