Does blutooth connection make audio sound a nocticeble difference with chromcast via wifi or airplay?

I use a android phone to stream Spotify music to ever solo a8 via blutooth and a Spotify direct access within ever solo a8 (This method can let ever solo access the sever of Spotify directly by World Wide Web ).
and noticed the blutooth connection make audio lack of energy and power

Do I miss any setting to make blutooth connection sounds worse?
 
Bluetooth is lossy compression. Its mandatory codec SBC runs at 320 kbs at its best. There are codecs with a higher bitrate but Bluetooth audio is capped at 1000 kbs.

The best Bluetooth codec is LDAC (up to 990kbps). With LDAC ( provided good full transmitter and receiver transmitter power so it works as it should) I have a hard time believing that there would be any audible sound bottleneck LDAC vs. lossless.
The bottleneck is by the way, as usual, speakers and/or headphones.

If your android phone has, supports LDAC Bluetooth codec, your Eversolo needs to support LDAC and it doesn't seem to have it:
Bluetooth BT5.0, support SBC/AAC


Here's a tip, a receiver for around $60 that has LDAC and also PEQ functionality:


LDAC test:

But first check if your android phone supports LDAC codec otherwise it is no idea to buy a FiiO BR13.

I think you've mixed up bit rates for mp3 and SBC where the recommendation for high quality is 328kbit/s for 44.1kHz sample rate and 345kbit/s for 48kHz. It can go higher, and a lot of receiving devices support that, but Google limit Android to that recommendation. If you've got linux, LineageOS or some of the other Android-based operating systems you can enable the higher rates.

No.
What I understand is the size of the bitpool defines the bitrate. Most OS limit it to 53 resulting in a 328 kbs stream.
 
Indeed - 328 kbit/s for SBC, not 320 as you stated which is the upper limit for mp3, hence me thinking they were conflated.
Edit: It was the author of that article that initiated the change in LineageOS as mentioned at the end of that article, and it changed in various other linux bits soon after.

I don't use bluetooth on my android phone for streaming, I use my network/wifi/dlna.....but the android device may make a difference with Spotify Connect (assuming that's what you're referring to in the Ever Solo that connect directly to Spotify). If I use my older Lenovo pad, I don't get lossless audio, but I do with my newish Android phone (Pixel 7a) when I use the Spotify Connect feature in my Denon avr.

Bluetooth is not to blame for that.

...And the lossy compression is usually very good, although it's "nice" to have lossless. Sound quality is more-related to the particular headphone or in-ear design.

I don't know that much about Bluetooth devices but with regular headphones/in-ears there is almost no correlation between price and sound quality. There are moderately priced headphones with very good sound quality and expensive headphones with poor sound quality.
 
I have tested different signal qualities with my active XTZ Tune 4 speakers.
They have analog input, digital input (internal DAC of unknown quality) and Bluthooth aptX codec.

For the analog input I have tested Spotify lossless (WiiM Mini digital out to DAC, analog in speakers) and via my DAC's Bluethooth LDAC.
I don't know if I hear any differences. What I do hear, however, is WiiM Mini's RoomFit on or off together with those speakers. Then in the bass area where the room messes with the bass response, higher up in frequency the speakers are surprisingly even. :)

Here if you want to listen to the same piece of music SBC vs aptX codecs:

Edit:
Maybe, if I listen to some obscure internet radio channel with terrible sound quality via XTZ's built-in Bluetooth, I would hear a difference between it and the same recording lossless. Or I can hope for that, because what would be the point of being interested in HiFi if you couldn't hear any differences at the rudimentary level. :oops:

I think - even at relatively low bit rate codecs (eg 300kb/s) it is very difficult to hear any difference in real world listening between that and lossless. There are online tests you can take if you want to check if you can really hear the difference - such as the one above for comparing SBC with aptX.

Far more likely that if what you are hearing is real (and not perceptive bias - for example caused by an unconscious belief that bluetooth will sound worse) is that there is a level difference between the output of the bluetooth decoding, and the lossless decode electronics in your A8. If you turn up the volume a little when listening to bluetooth, do you get the energy and power back?
 
It's also not unknown for manufacturers to apply different EQ to different bluetooth codecs - maybe marketing wanted to be sure you could hear a difference between them? Really we need measurements to know whether there's a real difference, and what the cause may be.

As you are probably listening knowing if it is wifi or bluetooth, the difference you are hearing has a 99% probability to be perceptive bias.
Until you compare without knowing what is what, making sure the output level is identical, you will never know.
Even, if half this forum tells you that there is no perceptible difference, your perceptive bias will tell you other wise.
