BioSport Earbud (Blue)

Good Quality sound, niece carrying case with a few spare ear pieces. Stays in my ear when i'm running which was very important to me. I haven't tried heat rate feature however so far I love ear buds.

The SMS BioSport Earbuds could have and should have been a boon to runners using the Sony SmartWatch 3 to track their runs on their smartwatches, except:1. SMS Audio did not implement the BTLE standard which would have allowed their HRM to work with almost any Heart Rate Monitoring Android Wear app (e.g., Ghostracer).2. SMS Audio did not work with Ghostracer (which displays heart rate with other running stats on the SmartWatch's display) to make sure it supported their HRM (it does not).3. RunKeeper does not bother to display HR on the SmartWatch's display.So if you want to monitor your heart rate while you are running you must use RunKeeper AND either:1. run with your phone in your hand, continually looking at RunKeeper on the display, and trying to read it in the bright sunlight as you runOR:2. enable current HR in the RunKeeper audio cues and wait for the audio cue to hear your current heart rate. However you have to wait for the audio cue (every 5 minutes? every mile?) and if you miss it when it comes up, you'll just have to wait for the next audio cue! This is not very useful and may be even more annoying than trying to read it from your phone as you're running.The opportunity to make this a great tool for runners has been squandered by SMS Audio and RunKeeper. Although I have become accustomed to using it with Runkeeper and the audio cues, it would be so much more useful if either:1. Runkeeper displayed average and current HR on their SmartWatch 3 app display, or2. SMS worked with Ghostracer or other SmartWatch 3 running apps that display HR infoIn spite of these shortcomings, I like the SMS Audio BioSport Earbuds because I don't have to charge them. I listen to Pandora while I run so I have to have my phone with me anyway, so plugging the earbuds into my phone and not having to charge them is a major advantage. They also have a very good sound. If they would fix the problem of displaying HR on my Sony SmartWatch 3, they would get 5 stars.ADDED 12/06/2015:I just got a new phone, the Nexus 6P. Runkeeper will not connect to the heart rate monitor at all on this phone. Occasionally the headphone jack does not even register the Biosport as being plugged in at all and the music comes out of the speakers. This does not happen with other earphones. But even when the music does come through the earbuds, Runkeeper does not display the Heart icon on its Start page at all, indicating that it is not connected to the BioSport's HRM. For this reason I am changing my rating from 4 stars to 1 star.Check the SMS Audio FAQ page at http://smsaudio.com/pages/faq for compatible devices. It is currently a very short list: Apple iPhone 4S, Apple iPhone 5, Apple iPhone 5S, Apple iPhone 5C, Apple iPhone 6, Apple iPhone 6 Plus, Samsung Galaxy Note II, Samsung Galaxy Grand II Duos, Samsung Galaxy S4, Samsung Galaxy S5, LG Nexus 5, and Motorola Moto X (2013)

After loosing the ear bud on the side with the sensor and using one of the replacements that came with it. The ear bud falls out all the time. I cannot complete a workout with it in my ear and the others all too small. They got me for 150, dam sure you will not get me again. Zero product testing is what this small thing means.

heart rate monitor doesnt work at all, app says connected, bluetooth says connected...but no heart rate. Contacted by email the company as they requested if there is any problem, but they just emailed back wanting a phone call. no time for that. Husband is the one that wanted them, and doesnt feel the heart rate monitor is as big a deal and waterproof sound (its only been a week) but he's happy so far there, and I didnt pay the original 100+ tag on them, so 3 stars for he got what he wanted at what I would normally pay for sports water resistant buds, but bad advertising.

These are decent headphones and do seem to do a reasonable job of measuring the heart rate. They now (6-15-16) only work with iSmoothRun if you are using an ipod or iphone (costs $5), but since they are available for $35 it is by far the cheapest way to get your heart rate - particularly if you needed a pair of headphones anyway... Probably wouldn't make as much sense at the original list price of $150, though!

Thoroughly enjoyed these Earbuds - they stay put - don't wriggle out of place when running and are wonderful at cutting out surrounding noise - specially in a gym.

Do not waste your time with these earbuds. The sound is average at best and the primary feature I purchased them for (heartbeat tracking) does not work. It only integrated with the RunKeeper App and they no longer support the integration because of all the issues they had getting it to work.

It's either these are fake or the quality is just not great. I bought these as replacement for my Klispch audio earbuds that broke. The sound is not even close .
