Should I buy a used Sony WH-1000XM5 or a new Soundcore Space One Pro?

If the price gap isn’t huge, I’d lean new Soundcore Space One Pro for most people. If the used Sony WH-1000XM5 is in excellent shape and priced well below the Soundcore, it can still be the better pick for stronger ANC and more premium sound.

Pick the used Sony WH-1000XM5 if:

• You want the more premium listening experience and stronger noise cancellation.
• You’re comfortable checking the condition carefully before buying.
• The savings are big enough to offset the risk of used wear.

Pick the new Soundcore Space One Pro if:

• You want a fresh battery and no mystery about prior wear.
• You’d rather have the safer buy with no used-condition surprises.
• You want a very capable headphone without paying flagship prices.

Simple verdict:

• Best sound/ANC: used Sony WH-1000XM5, if it’s genuinely well kept.
• Best low-risk value: new Soundcore Space One Pro.

A used wireless headphone will usually have some battery wear, so with the Sony you should expect less battery life than when it was new, depending on how much it was used.
