You hear deep bass, clear mid range as well as brilliant high frequencies

The sound is quite clear and crisp, however bass is lacking and the trebles are too higher, piercingly high at times

some of the highs are a little too tinny for my taste on some songs, but the bass is nice and deep and sound is clear.

If one thing could be better it is a deeper bass, but this is if I am nitpicking

The bass is also really impressive

The audio is not harsh but more rounded, the bass is excellent, the voices clear and I can hear the drums perfectly

The earbuds have a strong bass, which is ideal for to to practice at the gym

I rated only 4 stars because the headphones feel a bit heavier than I'm used to, the bass isn't as strong as I'd hoped, and while the magnetic clips are a great feature I do find them unclasping on their own occasionally.

The bass is not overwhelming (and often muddled) as with some of the others, but provides it at a level that I find pleasing.

Amazing earbuds for the price, nice bass and good highs

Really great bass and good pairing

The sound is really nice , Bass is good and

These ear buds are the greatest pair I have ever bought the sound is awesome and the bass is phenomenal

The bass is awesome, they are very lightweight, and low profile.

I'm amazed at the clear crisp sound, Great bass and treble

The fit is more comfortable than other earbuds and the sound is balanced from highs to rich bass similar to what I would expect to hear from the studio monitors

Absolutely awesome Bass and battery life

Great high’s and awesome bass

After testing these out I do think that the acil A1's are the best value, great sound quality, very good bass and nice battery life

Sound quality is amazing includes perfect bass effect and sharp sounds.2 things I would say would make this much more awesome are1

I'm not a hardcore audiophile but most of the in ear headphones that I've used either have decent bass response but sound dull on the higher frequencies or have clear highs but wind up sounding tinny because of poor low end performance

Good bass.

(Although the bass is good with these!

The bass is not overwhelming (and often muddled) as with some of the others, but provides it at a level that I find pleasing.

These produced sound that was at least as good as, and in some cases much better than, the more expensive options.

Great high’s and awesome bass
