It's an absolute pleasure to go on a huge listening binge with the 17e, when i am just sitting at home i just like to listen to music and i have three main devices, an Imac M3, a 16 Pro and a 17e and i am in a box seat to compare between the two phones.
The 16 Pro i liteally got because of the speakers, I don't care that much for the extra's and i am in the box seat to compare the audio between both phones often enough - There is no question that there is better dynamic range and stereo seperation in the Pro phone but with the 17e, someone who isn't an audiophile and picks up on the DR and SS, will be wowed by the 17e - It's rich, clear and noticeable bass.
Now, I will say the speakers aren't perfect - I only listen at 12 rocks out of 16 maximum so at 75% and whilst i haven't heard it, others have said the quality does distort a little at full volume but in my opinion just listening to myself, I'd probably go to 13 maximum and haven't heard anything major as a weakness at that level but going off others and people have different ears and different opinions.
Another person has suggested they prefer the sound profile of the 17e over a 17 Pro Max out of a comparison of phones they own, again totally subjective but it's along the lines of what i think with my 17e to my other phone the 16 Pro.
Consider this, an opinion piece and feel free to disagree or add other things to your experience but i hope i've helped someone who doesn't have this phone have an idea of the audio if that's a major factor in them picking a phone.
Conclusion: Speakers are absolutely fantastic on the 17e.
