I witnessed the true wireless headphones developments since the day of Bragi Dash back to 2014, the downfall of Doppler Labs with Hear One earbuds in 2017 and Kanoa’s scam.
True wireless earbud is a tough business except big names such as Apple, Samsung.
In the next couple of years with 5G and IoT we are expected to see more interesting things with TWS.
For now my predictions for 2020. This post was originally published in 2019 and I frequently update it.
To extract the most out of a track, earbuds can enhance the sound that you would be heard. This can be done by figuring out user’s hearing profile – how you hear the sound at different frequencies. The earbuds then auto-calibrate to match that hearing profile.
Bose recently announces it will close all retail in some regions, because most products such as speakers, headphones are increasingly purchased online. When you look for a pair of earbuds, sound quality is what you can get to know by reviews, but for the fitting it’s quite tricky. The fitting test will give the information how the earbuds will fit into your ears. Just by taking a photo of your ears, uploading to the fitting test app, it will give a percentage that indicate how well the earbuds fit such as if they are too large for your ears.
Battery tech is steady moving forward – it is smaller and holds charge longer.
True wireless earbuds (TWS) get benefit from it.
The current longest battery life for true wireless earbuds is 6.5 hours.
Quick charging is a great feature – 5 minutes of charging gives a lot more than you expected 2 or 3 hours of listening music.
It is not just the battery, the ultra-Low power consumption chip will consume less battery, making earbuds last even longer.
Qualcomm QCC5100 chip for example can manage the power more efficiently and saving 65% power for earbuds’ battery compared to their current chips made for small Bluetooth audio devices.
Balanced Armature drivers also requires less power to operate than dynamic drivers (aka moving coil unit).
BA drivers are also smaller, leaving more room for other hardwards or battery.
Bluetooth 5.0 seems to be the fit for IoT. It’s uncertain it will improve the sound quality but the Bluetooth connectivity is easier to set up. If your phone supports Bluetooth 5.0 – it can simultaneously connect to 2 separate earbuds, no more the need for syncing between 2 earbuds.
The latency means the delay users encounter when watching movies. The audio lags behind the video. Similarly you play game or wear VR headsets – it’s quite irritating.
New technology with ultra-low latency will erase the gap by increasing either transmission bandwidth or Bluetooth transmission efficiency.
Active Noise Cancellation
Active Noise Cancelling (ANC) isn’t necessary, though this term is often highlighted in marketing campaign.
If it works consistantly like Bose QC series – it could be a good thing but most of them don’t.
Just in some situations such that noisy subway – other than that it won’t matter. And if you switch ANC on it will consume a lot of battery, but it’s not true for Airpods Pro, with ANC switched on the Airpods Pro are still able to play less than Airpods 30 minutes.
If you think Apple Airpods sound great – Nope it’s not a standard for sound. You can easily find a pair that offers a better sound – because it provides better noise-isolation therefore better bass and richer sound.
Longer lasting battery and better sound aren’t trade off – earbuds will look bigger and may cause discomfort. And they also need a larger charging that may not fit into your pan pocket.
Better sound also means more drivers, BA will be used with DA to cover the wider frequency range.
Other than plastic, wood or carbon fiber will be used as housings for earbuds.
Earbuds will couple with smart wristband. When not in use earbuds can be stored and charged in wristband, you no longer have to take a carrying case with you on the go. Wearbuds have already run their campaign on Kickstarter. Aipower becomes the first wristband that host true wireless earbuds. Browsing on Aliexpress you can find several wristbands.
Call quality is better
Not just for listening music, Bluetooth earbuds should delivers the call performance as good as Bluetooth headsets. So you can call back your friend or your business partners with a double touch/press without removing your earbuds.
More microphones will be built into earbuds to detect and filter out the background noise. This counts on the Bluetooth processors, the Qualcomm QCC3020 supports 2 mics for noise reduction. The microphone sensitivity will improve until the call performance of earbuds reach the professional Bluetooth headsets.
Portless charging case
Iphone probably will go portless.
The wireless charging technology recently reaches a new milestone, it charges faster and more phone makers ultilizes this tech. Eventually the Micro USB type C or not won’t matter. The charging case for TWS gets benefit from this trend.
How much do you pay for a good pair of TWS?
From $80 to $100 you get a quality TWS such as 1More Stylish True Wireless with solid connection, great build quality, 6.5 hours of battery and wise sound.
