Just before Xmas I was excited to hear that SMS Audio had a set of headphones that could measure your heart rate . I could then compare this product to the Jabra Pulse product that I had reviewed on this site.  I bought them at the incredible price of £12.99 and then I realised what was wrong after I contacted the company directly. They stated that the company has gone into administration and that the products were being sold at discount through channels. This is a real shame. The product I tested did not work with the App recommended. The headphones did fit very well and the sound which was described as “Music studio mixed by rapper 50 Cent ” was OK but not top end.  So if you are tempted like me to get the product at a discount price please bear in mind the heart rate monitoring won’t work. You are getting a pair of nice fitting headphones that’s it and at £12.99 at TKMAX that’s a bargain. It’s a shame that the co-operation with Intel (Intel Inside) didn’t work out. I returned mine to TKMAX and said that they didn’t work with the App. Not 50 Cents then more like £12.99.
