Benefits of a Bluetooth Headphone

Bluetooth headphones are now gaining popularity over wired ones for various reasons.
The most obvious reason is that it allows the user to be hands-free.
While we always want to be focused on our game or work, there are times that we have to step away for a tiny moment, but we do not want to lose our conversation with our fellow colleagues and that is when a Bluetooth headphone comes in.
Other benefits include:

  • Inexpensive Headphones: With gaming gears flooding the market now, the prices are pretty much affordable while also maintaining their quality.
  • Automatic and User Friendly: We know that newer headphones are designed to be user-friendly for the comfort of those using them.
  • Low Interference: Despite the many other devices connecting to Bluetooth, headphones are relatively interference-free, allowing for a smoother gaming experience.
  • Energy Efficient: Due to advances in battery technology and microchip power usage, headphones today do not require as much juice as before.

So now, let us dig deeper and look at how BlitzWolf AIRAUX AA-ER2 could benefit you and what our experience with it was.

Overall Feel and Experience

  • The headphone uses the latest V5.0 Bluetooth technology, so we did not really feel any lag. Sure, a technical analysis might reveal a few milliseconds of delay, but the ear would not really perceive it while using the BlitzWolf AIRAUX AA-ER2.
  • Also, one major benefit we liked about this headphone is that it has less ambient noise due to it being over-ear.
    That means that even if there is too much noise coming from the background, such as the honking of horns or construction equipment drilling the whole day, you probably would be unaware of it because the headphone covers your ears in whole, and the padding surrounding it absorbs the surrounding noise.
    The BlitzWolf AIRAUX AA-ER2’s fine design allows it to be gentle to the ears.
    It also has good breathability as it uses only the best elastic protein leather material.

What We Liked About the BlitzWolf AIRAUX AA-ER2

There are two modes that can be switched freely, Bluetooth mode and wired mode.
So yes! Do you feel like using a wired connection for today? You can always do that.
But at any time that you need to be hands-free or perhaps you need to do a chore at the other side of the room, you can always go to Bluetooth mode.
Users have described this feature as very useful.

Another great benefit that users have said about the BlitzWolf AIRAUX AA-ER2 is that you can use it almost endlessly from just 2 to 3 hours of charging.
Its playback time is rated for 20 hours, hence, you only need to charge it once a day and you are pretty much set.
For those living a busy lifestyle, this is very critical.
When the battery is about to run out, its LED indicator would flash quickly to alert you.

Lastly, with the headphone’s 9D stereo surround sound dynamic diaphragm, listening to the sound made is like listening to it in real life, even better given the enhancements and effects due to the BlitzWolf AIRAUX AA-ER2’s dynamic graphene diagram.
Of course, the ideal is for you to keep the volume level at just 85dB to keep your ears safe.
While there might be apprehensions about 9D being too dangerous to the ear as it could possibly cause tinnitus, so long as you stay within the safe limits, you should be good.
