Bluetooth Audio - the Codec Confusion

Screenshot of the aptX logo being displayed on an Android phone.There are many Bluetooth profiles and the one dealing with streaming music is called A2DP (Advanced Audio Distribution Profile). Handsfree headsets intended for phone calls might use the Headset (HSP) or Hands-Free (HFP) profiles but headphones intended for listening to music uses A2DP.

The A2DP profiles requires that all devices support the SBC codec (low-complexity subband codec) as a simple, fall-back codec to be used if nothing better is available.

Jabra Elite 65t vs QCY Q29 truly wireless earbuds

The brand new Jabra Elite 65t are supposedly among the best truly wireless headphones/earbuds you can buy today and I paid €195 for them.

The Chinese QCY Q29 wireless earbuds are about as cheap as they get - I paid exactly €20 at Aliexpress.

Apart from the price, the difference between the two are surprisingly small. Let's compare.

Just looking at the retail boxes and opening them up might make you think the QCY headphones are the expensive ones.

Truly wireless headphones - why so difficult?

For years now, I'we carried a small case with a pair of Ultimate Ears in-ear earbuds in my pocket. Every now and then when I commute or walk, I take them out, plug them into my phone and listen to music.

When Apple said they would remove the headphone jack on the iPhone I was not impressed. Apple has been a forerunner when it comes to rid tech of legacy - such as the disk drive - and in hindsight they have been right so I accepted the death of the headphone jack.

Switching from iPhone to Android

After about 10 years in the iPhone camp i did the switch - I replaced my iPhone 6S Plus with a OnePlus 5.

It was a simple and painless process and my only regret is not having done it sooner.

For years, I have been following how Android phones have been catching up with the iPhone but chose to stick with the iPhone because I had put quite a lot of money into iPhone applications and considered myself stuck in the Apple ecosystem.

I recently realized two things:

Using Google Drive to sync content on one or more RetroPie/Raspberry Pi

If you are running RetroPie on Raspberry Pi to play retro games you have probably spent more time setting it up and configuring it than actually playing. And if you have two or more...

Wouldn't it be nice to manage the roms folder on a Google Drive folder and let it sync to one or more RetroPies? And if you spent time scraping metadata and box art on one RetroPie that would sync to the others without additional work.

It's kind of possible. But it is slow and you will have to initialize the syncing and choose sync direction manually.
