Why Hearables Should be Your Number One Choice for the Gym

Here’s why hearables, and not wearables, are the best option for most gym activities and fitness enthusiasts.

The familiarity of wearing devices on the wrist and arm is one reason why most biometric devices are sold as watches or wrist bands. However, there are some significant disadvantages of wrist wearables that can affect the accuracy of the device when compared to other locations on the body.

Even though this might seem contrary to popular belief since the wrist and neck are the two locations where people are taught to take their pulse, there several factors contribute to the overall accuracy in wrist wearables. Just because the pulse can easily be taken by simply feeling for your heartbeat on the thumb side of the wrist doesn’t mean accurate data from a wearable can be obtained in this area of the body during activity.

In actuality, the wrist is one of the most difficult areas of the body to measure biometrics accurately. Since most wearables use optical sensors to shine light into the body to measure the amount of scattered light due to blood flow, accuracy can often be comprised in locations where there are more bone, muscles, and tendons. For more detail on how these devices work, see Optical Heart Rate Monitoring: Everything you Need to Know. Because the wrist has a high number of bones and tendons, the basic physiology of the wrist can often skew the accuracy of the measurement. Accuracy can be further decreased if your primary activity puts physical stress on the wrists like you might find with cross-fit workouts or weight lifting.

While wrist, arm, and leg wearables are usually in motion during a workout, the ear is a more stable part of the body where optical noise from movement is limited. Bones, tendons, and muscles that can also disrupt the accuracy of optical sensors are minimal in this location as well, enabling a much cleaner optical signal to process.

Another reason why the ear is an ideal location for gym-based workouts are the number of arterioles located in the ear. Since arteriole banks found in the ear are connected directly to the carotid artery system, it is easier to obtain accurate data from blood flow characteristics and provide accurate feedback of what exactly is going on in the heart during exercise.

Last but not least, earbuds are a popular workout companion for many gym users, so it makes sense to include heart rate sensors in this form. Audio electronics like an iPod or smartphone can still be used without affecting accuracy of the device, and unlike a wrist wearable you can get real-time audio feedback without having to stop and look down at your device. This makes earbud-based wearables an all-in-one device that should be just as familiar as watch or band-type devices that many consumers have grown accustomed to.
