SMS Audio might not have made 50 Cent a billionaire like Beats did with Dr. Dre, but believe it or not the company actually makes some pretty good products. In fact, since entry-level products from Beats are more about image than they are about quality, some SMS Audio headphones are even better than options from Beats. And then there are some SMS products that do things no Beats headphones can pull off.

Here’s a perfect example: the SMS Audio BioSport Earbuds cost just $51.40 on Amazon with free shipping, and they can monitor your heart rate in addition to delivering good sound quality, a comfortable fit and much-needed noise isolation.

Some key details from the Amazon product page:

  • Biometric Earbud with heart rate monitor
  • Professionally tuned 12mm drivers deliver tight bass and dynamic mid-tones.
  • No need for uncomfortable straps or multiple devices.
  • IPX4 rated for resistance to sweat and water.
  • 3.5 mm gold-plated audio jack delivers all the power you’ll ever need for biometric monitoring. Nothing to replace or recharge.
  • Intel Inside
