Rulefiss BX27 Wireless Earbuds Sport: Bluetooth 5.4 Technology
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.
