Tethered or not tethered is not too concerning.
I want louder.
BT sounds a good way to try as well.
I don't fancy going to a store and trying plenty of sets as they are generally in tight packets and it is not possible to say how they will sound.
I am hoping someone will say: XYZ model are louder than the standard set!
Anyway I see in the section below several entries about earphones I will now chech them.
Hi again
Peter.... - well, please provide some more information: 1) Are you referring to the Apple Earbuds shown below, and if so, is the volume adjustment working properly; 2) Have you tried the earbuds w/ another audio system (e.g. stereo, iPod, or other); and 3) Have you upped the volume on the Mini or tried another set of earbuds or headphones? Sorry, if you have already gone through this routine.
Personally, I've never liked earbuds - don't seem to fit my ears, keep falling out, and sound levels always seem low (w/ much ambient noise) - but, I've not tried that many nor was willing to pay for the more expensive ones - so, you might want to consider an over the ear headphone, whether wired or wireless. Do you have (or could you borrow) some different earbuds and/or headphones and give them a try?
Now, as to
loudness, what is loud for you? Ear damage is always a possibility when listening to music at high volumes over prolonged periods - second pic below from
HERE showing that at 90 dB or above, ear damage becomes a consideration - this is just a general comment for all reading this thread and who may be concerned about volume levels on their earbuds or headphones - P.S. keep in mind that this is a log scale, thus an increment of 10 is really not a doubling but 10X the loudness.
Hope others will 'chime in' w/ their experiences - but my BT headphones (about $60 at Best Buy) provide plenty of sound from my iPad Air 2 - good luck in your selection. Dave
