Honestly, the XM6 isnt even out yet and rumors are just guesses at this point. I wouldnt hold my breath for a Prime Day deal on a product that doesnt exist. Since you are on a $300 budget for that Chicago commute, you should focus on what actually works right now. I have been through plenty of these and you gotta be careful with the newer designs.

• Sony WH-1000XM5 Wireless Noise Canceling Over-the-Ear Headphones
• These have the best noise cancelling for trains, but they dont fold up small which is a pain for commuting.
• Sony WH-1000XM4 Wireless Industry Leading Noise Canceling Headphones
• My personal recommendation. They fold flat, the ANC is almost as good as the M5, and they will definitely be under $250 next week. Make sure to check the hinges on the M5 before buying tho... they feel a bit flimsier than the older M4 model. I would suggest going with the M4 and saving the extra cash.

Unfortunately, the Sony WH-1000XM6 is not a real product yet, which is disappointing for anyone needing an immediate upgrade. Sony generally follows a two-year release cycle, and we are currently in a gap. You wont find deals on a model that hasn't been manufactured. Since your budget is strictly 300 dollars and you need to block out Chicago train noise, you should look at the <a href=" https://www.bhphotovideo.com/c/search?Ntt= Sennheiser+Momentum+4+Wireless&BI=8941&KBID=10361&SID=12345&DFF=d50" target="_blank" rel="nofollow sponsored">Sennheiser Momentum 4 Wireless. The technical specs are superior in terms of battery life, offering 60 hours compared to most competitors. Another reliable choice is the Bose QuietComfort Headphones. They frequently drop to around 249 dollars on Prime Day. The Bose ANC is technically more consistent with low-frequency engine hums, even if the software features are a bit basic. It is a shame the M6 isn't out, but these are better value right now.
