Hey there nsa046,
Thanks for reaching out to the Apple Support Communities.
To get started, how are you listening to music on your iPhone? For example, are you listening to music though Apple Music, or are you using another app. If using the Music app, check out the steps in the following resource that can adjust how your music sounds: Change the way music sounds on iPhone - Apple Support
* Choose an equalization (EQ) setting: Go to Settings 
> Music > EQ.
* Normalize the volume level of your audio: Go to Settings > Music, then turn on Sound Check.
If you're also subscribed to Apple Music, do you by chance have Dolby Atmos enabled in Settings > Music > Dolby Atmos? If you do, are the devices you're connecting your iPhone to Dolby Atmos compatible. If they are not Dolby Atmos compatible, try turning this setting off and test the issue again.
If your devices are Dolby Atmos compatible and this setting is disabled, trying turning Dolby Atmos on and test the issue once again. For more details, check out this link here: Listen to Dolby Atmos music on iPhone - Apple Support
In the Music app 
, Apple Music subscribers can listen to available tracks in Dolby Atmos. Dolby Atmos creates an immersive, three-dimensional audio experience on stereo headphones and speakers or receivers compatible with Dolby Atmos.
Note: Dolby Atmos music isn’t available in the Apple Music Voice Plan. For more information, see the Apple Support article How to use Apple Music Voice.
Albums available in Dolby Atmos have the Dolby Atmos badge 
. If a track is playing in Dolby Atmos, the badge also appears on the Now Playing screen.
Note: Apple Music and Dolby Atmos aren’t available in all countries or regions. See the Apple Support article Availability of Apple Media Services.
Turn on Dolby Atmos
1. Go to Settings > Music > Dolby Atmos.
2. Choose Automatic or Always On.
* Automatic: Plays Dolby Atmos whenever iPhone is connected to compatible headphones such as AirPods (3rd generation), AirPods Pro, or AirPods Max, or to speakers or receivers compatible with Dolby Atmos.
* Always On: Plays Dolby Atmos on any headphones or speakers. The Music app will attempt to play Dolby Atmos tracks on any headphones or speakers connected to iPhone.
Dolby Atmos will play on any headphones, but not all speakers will play Dolby Atmos as intended.
Keep us updated on the results.
Take care!
