Buy the TRAUSI Wireless Bluetooth 5.4 Headphones.

It's the only one of the three you can actually check out, and it's also the cheapest and best reviewed.

What was compared

Fhumsh Wireless Earbuds/Running/Work（Black） : Electronics — $250.00
TRAUSI Running : Electronics — $169.99
TRAUSI Wireless Bluetooth 5.4 Headphones, Fast Charging Stereo Earphones with Noise Cancel... — $18.99

1. The one you can actually buy today
Fhumsh and the TRAUSI Running model both show as 'Currently unavailable' on their product pages. Whatever they promise on paper, you cannot order them, while this TRAUSI ships now with Prime.
2. Backed by hundreds of buyers, not a few
This model carries 662 ratings against Fhumsh's 75 and the TRAUSI Running's just 19. A rating built on 19 reviews can swing wildly with a few bad orders, this one cannot.
3. Better rating, from way more people
At 4.2 stars it beats Fhumsh's 3.6 and the TRAUSI Running's 3.2, and it earns that score across a much bigger crowd of reviewers. That is a real gap, not rounding noise.
4. Same kind of earbud, a tenth of the price
All three are budget Bluetooth workout earbuds with IPX7 waterproofing and a noise cancelling mic, but this one lists at $18.99 against $250 and $169.99 for the others. You are paying for a bigger number on the tag, not a different product.
5. Yes, Fhumsh claims 50 hours. Can't buy it.
Fhumsh's page brags 50 hours of playtime and an LED display, a genuine spec edge on paper. But it is currently unavailable, so that battery life is theoretical, while this TRAUSI is in stock and comes with fast charging you can actually use.
