Rulefiss BX27 Wireless Earbuds Sport: Bluetooth 5.4 Technology
Ever been in the middle of a workout when your earbuds decide to take a dive? Not with our Wireless Earbuds Sport. Thanks to Bluetooth 5.4, they stay connected like your favorite gym buddy, and with 75 hours of total playtime, they might just outlast your motivation. Plus, they’re IP7 waterproof and come with secure earhooks because nobody has time for earbuds that bail during a sprint.
But wait, there’s more (and it’s good):
- Feel the bass drop with 14.2mm triple-layer diaphragm drivers—your ears will thank you.
- Chatting on the go? 4 ENC microphones make sure you sound crystal clear, not like you’re calling from a wind tunnel.
- Running low on juice? The quick charge feature and dual LED display have got your back, showing you exactly how much power you’ve got left.
- They come with multiple ear tip sizes because one size fits all is a myth, especially when it comes to comfort.
- And with sensitive touch control, skipping tracks or adjusting volume is as easy as a tap—no fumbling required.
