Bluetooth is a incredible characteristic on cell phones, however for those who use it to take heed to your favourite tunes frequently, you would possibly discover it typically sounds useless, tinny, or simply plain unhealthy. The offender would possibly truly be the default codec your cellphone is utilizing for Bluetooth.
Luckily, there are a couple of methods to enhance it, sometimes out there proper in your gadget.
Bluetooth high quality enhancements start with the codecs
Not all Bluetooth audio is identical
The media recordsdata you utilize daily require a codec to play again correctly. That is normally software program (however can often be {hardware}). It mainly takes knowledge, compresses it, and encodes it. The codec decodes the file right into a playable format on the finish level of the transmission.
Consider it like a translator that takes one language (music or video on this case) and converts it to a different (music being performed again through streaming or Bluetooth). It is an important operate for media recordsdata, no matter gadget or format.
Bluetooth audio can differ relying on the bit fee the codec makes use of for transmission. Bluetooth makes use of the SBC (Subband Coding) codec as its default and fallback, which simply occurs to have the bottom bit fee. It is lossy, like an MP3 file, which simply means it loses some knowledge when it compresses the audio.

LDAC is a codec value understanding about
Developed by Sony, adopted by Android
Your Bluetooth settings are most likely already set to SBC by default, though some units would possibly default to AAC.
AAC (superior audio coding) is an effective middle-of-the-road possibility, however LDAC (a format developed by Sony) is the setting to make use of for higher audio. LHDC is one other high-resolution format that sits alongside LDAC as a high-quality different to SBC.
LDAC helps 990 Kbps at 32 bits/96 kHz. If which means nothing to you, it simply means it is nonetheless high-resolution, sounds good, and would not lose as a lot knowledge throughout compression. It’s positively higher than SBC detail-wise.
In fact, utilizing LDAC with low-cost, low-end earbuds or a awful speaker most likely will not make a lot of a distinction.
In case your gadget helps LDAC or LHDC, it is value utilizing
Enabling LDAC and LHDC is less complicated than you suppose
Loads of units can be utilized as audio receivers, from audio system to headphones, to your laptop computer. Bettering audio high quality and tweaking settings is half the enjoyable of utilizing trendy tech. Relying in your consolation degree (and whether or not your gadget is supported), you’ll be able to entry and alter codec settings your self by your gadget’s developer choices. I’m working with two Android telephones, particularly a Motorola Moto G 2025 and a Samsung Galaxy Z Fold 5.
That stated, this is find out how to see in case your gadget helps LDAC and allow it if it does:
- Search for an LDAC or LHDC brand or spec sheet in your gadget’s directions.
- Examine cellphone settings by developer choices/settings
- Each cellphone has a special approach of accessing the developer choices. For the Motorola Moto G, you simply go to Settings – About – Gadget Identifiers after which faucet “Construct Quantity” eight instances.
- “Developer Choices” might be listed below “System”
- Discover “Bluetooth Audio Codec” and make the adjustment. On this case, I’ve enabled “LHDC”
The Samsung Galaxy Z Fold 5 has a barely totally different solution to entry the developer choices:
- Go to “Settings”
- Choose “About Cellphone” and go to “Software program Info”
- Faucet the “construct quantity” about seven instances
- Examine the codec below “developer choices”
- Repeat the identical steps as above
- The audio sounds fairly good by a pair of On a regular basis Earbuds, however your mileage might differ
Your particular gadget will differ, clearly, so ensure you lookup (ideally through the handbook or by asking assist) find out how to modify these choices on your gadget. LDAC ought to be supported on all Android Oreo telephones and above, which is fairly cool.
However what in case your gadget would not assist LDAC? Don’t fret, there are many different codec choices out there, like AAC, aptX, and aptX HD. Apple prefers the AAC codec, as an example, and it really works nice for his or her iOS units. AptX and aptX HD are Qualcomm’s options to SBC (they’re sometimes higher high quality, and most Android units assist them). No matter your case could also be, all of them just about beat SBC, however I like LDAC the most effective.
In the event you’re eager about studying extra about LDAC in a way more technical sense, the supply code is out there at The Android Open-Supply Mission.

Though everybody’s mileage with Bluetooth will differ, there are positively benefits to altering your codec settings. Outcomes will differ based mostly on headphone high quality and supply materials, in fact.
For me, LDAC might be my go-to on any new Android gadget, and I’ll be seeking to allow it any time I arrange my Bluetooth settings on future telephones and units.
