For this weeks blog we have an in-depth article on the Shokz OpenRun review: bone conduction sports headphones. These innovative headphones are designed for sports use. Perfect for triathletes in training. It is amazing to hear how these headphones have developed. Compared with our previous review of the AfterShokz Trekz Titanium they have come on a long way. Read what Jason has to say about his experience testing these following a 6 week trial.

The Shokz OpenRun headphones were previously marketed as AfterShokz Aeropex.  These are the same headphones aside from the charging has been improved for fast charging.

Summary of Shokz OpenRun Headphones Review

The sound quality of the headphones is very good considering how they transmit the music into your ears. In my opinion if you want a pure high end musical experience you wouldn’t look towards the sports headphones range. So if you are looking for a pair to use with sports then you need to be aware that you will have to compromise slightly in terms of sound quality to have the other benefits of a sports headphones. Waterproof, robustness and in the case of the OpenRun safety.  For sports headphones the Shokz OpenRun are an ideal choice.

First Impressions

When these arrived from the guys at Shokz I was really quite excited to try them out mainly because I had never tried the ‘bone conduction’ type of headphone. These are marketed on the concept that you can do your training (whatever that may be) whilst listening to music and at the same time have awareness of your surroundings. Surely a winner for those who run or cycle with music and who want to hear the potential dangers around you. Without further ado, let’s jump straight into the un-boxing and find out!

Unpacking the Shokz OpenRun

Unboxing the Shokz OpenRun

The box of the Shokz OpenRun headphones is approximately A4 in size, so its massive, just for some headphones. However, it sets the scene for what is coming up once opened.

Upon opening I was greeted with a reviewer’s guide booklet, a pen, black envelope, bag with the words ‘multifunctional headwear’ on and another box with the Shokz branding on. Which can only be the headphones themselves. A pen? Why a pen? Maybe it was in case I wanted to hand-write a review! It is actually quite a nice pen, wonder how long it will last at work before it goes ‘missing in action’.

First Impression of the AfterShokz Aeropex

The multifunctional headwear bag is actually a neck/head ‘buff’. I love a good buff and it is a good buff. Something I use in the winter for my running and cycling. The black envelope is a ‘Welcome to the world of Shokz’ note from the team at ShokzUK. Nice touch.

What is in the box?

On to the headphone box, opening that up you get the following items:

  • Rubber protective case
  • Instruction manuals, quick start card and warranty card
  • Two magnetic USB charging cables
  • Foam ear plugs
  • Headphones

A fair bit of stuff inside the big black box, hence the size. An excellent unboxing experience and it really oozes quality and attention to detail. Great start!

Charging the headphones

Hooking the Shokz OpenRun headphones to charge is quick and simple. The charging cable is USB so can be attached to any plug, computer or device with a USB socket. The end that actually attaches to the headphones is magnetic and simply ‘snaps’ into place on the underside of the right-hand side control unit. Shokz supply you with two charging cables. Which is handy as I have one at work and one at home. Meaning I shouldn’t ever be caught short with a flat battery. Easy peasy.

A full charge takes only 2 hours.

Battery Life of the Shokz OpenRun

A red light shows they are charging which turns blue when fully charged. Shokz say you should get around 8 hours of playback from a full charge. More on that later! They also have an in-built moisture detection safety mechanism. If you try and charge them when they are wet, you get an audible warning and they wont charge. A quick wipe and charging begins. I think this is great idea as I have destroyed many a pair of headphones with water ingress at the charging point. The charging point isn’t covered in any way though. Only time will tell if this creates an issue with charging or not later in life. Although being fully waterproof and magnetic should mean they will be super reliable in the charging department.

Battery life

While reviewing the Shokz OpenRun I have carried out 12 full charges over the 6 weeks of ownership. I have had a couple of weeks where I haven’t used them much but other weeks where I have used them for 4-5 hours a day.

First Charge results. 8 periods ranging from 30 – 90mins of usage. This lead to 9 hours on the dot until I had the voice assistant tell me I needed to charge them. She repeated these a further two times. Three warnings in total over a period of 10 minutes before they performed an auto shut down.

Second to Twelfth charge results. Each time the battery life has been consistent between 8:45-9 hours between charges. I have used them over long periods 4 to 5 hours in a single go. Also several shorter periods of 10 mins to 1 hour at a time and there doesn’t seem to be any difference in battery life from the different types of use. You can also check the battery status by pressing the volume down button when the headphones aren’t kicking out any sound. The voice assistant lets you know:

  • Fully charged
  • Half way
  • Low charge
  • 3 x recharge required (Final 10 minutes before auto shutdown)

9 hours is a good level battery life for Bluetooth headphones in my opinion. Yes, we would all love tons of battery life but in reality, we are kind of limited. A 9-hour battery life will be fine for all but any long ultra-marathons.

Comfort of the Bone Conduction Headphones

The OpenRun headphones sit comfortably over the ears and have a solid band that passes around the back of your head as you can see on the photos. They are super light with claimed weight of 26g.

Aside from a small amount of pressure at the headphone pods they are barely noticeable. They feel secure and they don’t budge when jumping around and shaking my head in a vigorous manner. One thing I have found with other types of headphones with a band around the rear is that the band makes the headphones ‘bounce’ up and down whilst running. No such issue with the Shokz OpenRun. They stay put and again you barely notice them when running or cycling.

Comfort of the AfterShokz Aeropex Headphones

Depending on what kind of helmet you wear when riding your bike, depends on how they sit. Helmets with low rear ends or TT pointy reared helmets push the band down slightly. This in turn could adjust where the pods sit on your temple. No great shakes but worth noting. These are not adjustable. So those with either larger or smaller heads than me may have a different fit experience.

Functional controls

The OpenRun headphones have three buttons:

  • Volume up/power on/off/Enter pairing mode
  • Volume down/Battery check
  • Play/Skip/pause

The volume up & down buttons are on the right-hand side and sit behind the ear. The play/skip/pause button is on the left-hand side on the pod itself. My initial thoughts on these buttons were that I was trying to press the play/pause button too hard. It took me a few days to find the balance of how hard to press it in quick succession to skip tracks. Turns out that you really don’t need a great deal of pressure at all. It is almost just a light tap. The power on/off/volume buttons were initially tricky to locate but the more I use the headphones the easier it gets to find the buttons whilst exercising.

Innovative Bone Conduction Headphones

After a period of familiarisation the buttons have a solid feel to them. They should certainly last as long as the rest of the product. Which is often the first failing point of headphones. They are easy to use once you are used to the commands and how to go about pressing them.

Sound Quality of the headphones

Shokz claim they have created a more bassy sound with less vibration with the OpenRun headphones. From what I have read that was a negative of previous incarnations that as soon as you turned the volume up, they vibrated against your head and it wasn’t a pleasurable experience. Whilst the vibration is there when you wind them up, I don’t find it bothers me at all. For me its more of a slight tingle on the temple area. Again, I don’t have experience of the previous models so I can not do a direct comparison here.

Cycling with the Shokz OpenRun

Overall the listening experience is a positive one in my opinion. I listen to a lot of music. I almost always run with music. However, I am not a fan of listening to music whilst cycling as I treat every other person on the road like they could kill me. So even though it is an excellent experience using these whilst cycling, my preference is not to use them whilst cycling. Mainly due to all my rides being on the open roads. If I had cycle paths or trails to ride, then I would probably use them more whilst cycling.

Cycling with the AfterShokz Aeropex Headphones

Generally, I have stuck to using these on the turbo trainer while reviewing the Shokz OpenRun headphones. With the noise of my turbo (Elite Drivo or a Tacx Flow), tv on and a fan, the sound through the OpenRun is still crisp and clear. This is with the volume set to between 50-75% and I can also hold a conversation with someone all whilst listening to music. If you wear ear plugs, the sound quality improves and I would say on par with regular in-ear headphones. Bass increases and all the harmonies are clear and crisp.

Running with the Shokz OpenRun Headphones 

I listen to a wide variety of genres, but tend to stick to dance/hard house / trance / hardcore / Rap whilst training. The sound quality is good.  Punchy bass (when using the ear plugs), bass is more of a crisp less punchy quality when ear plugs are not used. Vocals are crisp and clear and the high frequencies aren’t too high i.e. not sharp, but perfectly balanced with the rest of the sound.

Once you go outside and have the influence of traffic/road works/grass cutters/leaf blowers etc.  The sound dynamics are changed, I feel I had to run with the volume at a minimum of 75% to get the same sound experience as I did indoors. This doesn’t distract from the point of using bone conduction headphones from a safety view. I was still more than aware of my surroundings and could hear bicycle bells ringing, and other potential dangers on the roads/paths.

The only time I couldn’t hear the music was when I was running over a very busy A-road dual carriageway/motorway bridge. Equally running on the paths that run parallel (less than 20 metres) to these busy kinds of roads where the traffic noise was too loud. With this increase in volume required (more towards the 90%+) there is a slight vibration sensation present. However, for me it doesn’t ruin any of the enjoyment of using these headphones.

As the battery life runs down, it seems that the volume reduces slightly too. I am not sure if this a feature to try and save battery or not, but I had to keep increasing the volume slightly when I was close to the low battery notice. No biggie but something I will keep track of the more I use the OpenRun headphones.

All-Weather Headphones

These are fully waterproof with a rating of IP67 which is perfect for training in a high sweaty/moisture environment. After using these they have been soaked in sweat and rain repeatedly. The OpenRun haven’t missed a beat and giving them a quick wipe down after every use to return them looking as good as the day they were unboxed.

Using the Shokz OpenRun for phonecalls

From my review of the Shokz OpenRun headphones this is where the headphones drop in quality. The positive button press method of answering calls or making a call was fine with no issues when re-dialling the last number or answering a call. However, I found that I had to be in an almost silent environment to be able to have a conversation on my mobile phone (I-phone 10XR). In this environment, the open ear headphones were good enough to converse but occasionally cut out for a few seconds. Meaning I had to ask the caller to repeat what they had just said. Now this could well be down to phone signal, but it was a frequent occurrence unfortunately. I also found I had to really concentrate on what the caller was saying.

Review of the AfterShokz Aeropex Bone Conduction Headphones

Outdoors, this wasn’t a great experience. It was far too difficult to hear what was being said with the hustle and bustle of the outdoors. On maximum volume, which I had to have it on to hear the caller, the vibration was too much. It made me want to end the conversation and return to the old-skool holding the handset for a call. Therefore, I can’t recommend using these as a hands-free calling option unfortunately. One final note on taking calls. When the call ended and I returned to listening to music, the volume seemed to be less than when it was prior to taking the call, weird.

Shokz OpenRun Multi-pairing Bluetooth mode

Having two devices that I like to connect to, my phone and MacBook air. There is a multi-pairing mode where I connected to both sources for seamless transition between the two without needing to re-pair each time. Easy to use. Just enter pairing mode and pair with the first device. Then when I wanted to connect to the second device, enter pairing mode again
and select the headphones on the second device. This enabled me to switch around as I pleased just by selecting the headphones in my Bluetooth list on each device.

Sound Equaliser facilities

When using ear plugs (supplied or your own) to provide noise isolation. Let’s say when I was in a noisy gym or on the train, I adjusted the EQ affects to increase or decrease the Bass frequencies. There is a noticeable difference between ‘bassy’ and ‘non bassy’. However, it is
only noticeable with the ear plugs in though. Having tried it without them and there is very little difference except for a (very) slight change in ‘tininess’ between the two. I prefer the ‘bassy’ EQ in both instances of using and not using the ear plugs. To do this all I had to do was press and hold both volume up and volume down together when the music was playing, and Audrey told me the EQ had changed.

Summary of review of the Shokz OpenRun

“After using these for around 6 weeks I have, overall, had a great experience using them. “

Jason – Trivelo Expert Test Associate

The sound lows were crisp and punchy. Vocals crisp and clear and the highs not too sharp that results in a great balanced sound stage to any type of genre played through them. They do sound far better when wearing ear plugs. However, this defeats the object of being aware of your surroundings so this way should be saved for when they are used when chilling out at home, in the gym, on the turbo or on a train/aeroplane.

They held secure and I would say impossible to shift whilst running and cycling unless something extreme happened. Zero bounce and I hardly noticed that I was wearing them. The wet charging point warning is a great idea to stop you damaging the internals too, something that I have done with several pairs of headphones in the past. My last two pairs
(Jaybird X4) only lasting 4 months before they stopped working due to moisture ingress. The build quality of the Shokz open ear headphones is outstanding. A true quality feel about them and I believe they are more than up to the job of living with me as a user.

“The Shokz OpenRun are now my go to headphones for training”

Jason – from his YouTube video review of the headphones

Negatives from the review

The only negative aspect I found was using these in a noisy environment for calls. However, this would not stop me recommending using the OpenRun headphones for all but the purists out there who probably wouldn’t want to use them for sports.

Thanks & Disclaimer

I would like to thank the team at Trivelo for teeing up this review with Shokz and the team at Shokz for sending me a pair of OpenRun headphones to use and review. Shokz provided me with a single pair of headphones to review and at the end of the 6-week review period culminating in me supplying this review for their own use.  Shokz have kindly let me keep them free of charge. This has in no way swayed my review and everything in this review has been my own thoughts and experiences.
