Happy Thursday Everyone.  This week’s review is on Air TWS ear buds.  In the last few months, I have been on a quest to find a true wireless pair of Bluetooth ear buds that is a balance of good  quality, good value ($39.95 Cdn on Amazon.ca) with decent sound.

Build and Looks

Air TWS Case 

The Air TWS comes in its own charging case.  They come in all colours as long as it’s black.  Sorry, but they only come in black. The charging case is compact and sleek looking with a built-in loop on one end so you can attach it to your back pack or bag.  I wouldn’t suggest the ear bud outside of your bag or backpack however.  There is a button in the front which opens the case. At the back of the case is the input for the charging cable that comes with the package. Beside it are 4 LED lights which shows the charging status when the case is plugged in. Inside, are two magnetic slots to make it easier to align the ear buds to the IMG_0288charging contacts.  There are two LED lights.  One for the left and one for the right ear bud.  They glow red when your ear buds are charging and they will turn blue when the earbuds are fully charged.


The earbuds themselves look very sleek and solidly built.  They come with a little flexible rubberized hook for inside your ear to be more secure.  The control buttons are well designed and easy to find when you answering a call or to turn the units on an off while they are in your ear. The little rubber tips fit well in the ear and can be changed for a smaller one that comes with the set.

SZX-EP-101 (22)As far as the comfort of the ear buds, they are quite comfortable.  They sure beat having wires.  One thing that I like about this ear buds is when using them while in bed, you can actually turn your head on either side without worrying about crushing them against the pillow unlike the bulky wired ear buds or headphones.  The caution is it is easy enough to fall asleep while listening to your favourite music,  and having to look for them in your bed when you wake up. If you are like me, we have cats, and they love playing with these little things.  So you have to make sure to get in the habit of putting them back in the case after you use them. Otherwise, you will spend some time on an ear bud hunt every other day.

Set up

Setting up the Air TWS earbud is probably the part that is a little bit challenging.   Following the manual that comes with it is even more challenging since it is very hard to understand. The first time setting up the Air TWS was an exercise in trial and error.  Here are the steps in setting up the earbuds for first time use.

  1. Hold the power button down on both ear buds at the same time. A voice that says, “Sufficient quantity of electricity detected” will come on. Keep holding both buttons down until you see a red and blue light flashing on both buds.
  2. Click both ear buds twice together so they link to each other.
  3. Click on the right ear bud to pair it with your tablet or phone. Go to your smart device and look for Air TWS in the Bluetooth settings. Select it and you should be able to pair now.

After the initial set up, you should be able to just turn on both ear buds, and it will automatically pair with your smart device.

Bluetooth Connectivity

The connectivity between the left and right ear buds are consistent. I never experienced and drop off.  As well, the connectivity of the ear buds to the smart devices is pretty consistent and have a very good range.  I was able to walk around the house while leaving my tablet or phone in one place and the connection didn’t drop.

Sound Quality

20171202_141848The sound is quite good on the Air TWS.  It is quite pleasant to listen to.  The sound quality is well balanced between the high, middle and the low notes. The separation of the stereo sound between the right and left units are distinct and decent.  I would say the bass is better than average compared to other true wireless ear buds that I have tried. However, I would prefer a little more base personally.

Battery Life

The battery life when listening to music or podcasts is about 2.5 hours.  When the battery is low, you will hear a voice that says “Battery Low”. You can simply put the ear buds back in the charging case and they will be good to go again after 45 minutes, .  The case will charge the ear buds up to three times.  So this is a great gadget to have on long haul flights when you want to drown out the sound of a crying baby beside you or generally while on the go.


Phone Calls

The Air TWS can be used independently as a Bluetooth hands free ear bud.  I don’t use it much for that but if you need to, use it as a hand free device, it is good enough on a pinch.  The only down side is, the person you are talking to can hear the background noise, if you are using it in the car or in a generally noisy environment.


  • Great Value
  • Solid build
  • Great Sound
  • Compact
  • Good Battery Life
  • Charging Case charges the ear buds up to 3 times


  • Set up is a bit tricky but once done, it connects to your smart device as soon as the ear buds are turned on.
  • Sound could use a little more base.
