Audio Quality as headphonesThe sound quality of the audio is amazing. I love listening to music. I listen to a lot of music. I listen to classical music. I listen to 80s rock. I listen to modern music. I used to you work in audio hardware design at ABC radio in Sydney. I was trained as an electrical engineer in digital audio. I have been involved with sound mixing and acoustics for over 20 years. So it is with all that experience and expectations of a quality product from Apple that I say that the Apple Airpods sound beautiful.The sound is clear but not harsh. The bass is powerful and tight, but not muddy and not overpowering. I have read several reviews that say the sound quality of the Apple Airpods is comparable to the Apple earbuds – the wired headphones supplied with the iPhone. This is certainly not the case. The quality of the sound in the Airpods is significantly better than Apple’s wired earbuds. Compared to the Airpods, the earbuds sound thin and harsh. There are certain high-frequency sounds on the wired earbuds that start to irritate your ears after long periods of listening. There are no such frequencies on the Airpods. The bass on the Airpods is much clearer. They may not sound more ‘bassy’ but if you compare the two headphones and listen for a bass guitar riff or a kick drum you will notice that the clarity of the air pads is much better. They are in a different league to the old Apple earbuds. I would be comparing them more to my Bose quiet comfort headphones and they stack up pretty well. I would happily use the Apple Airpods as an In-ear Monitor for a band. They sound great.Overall I am very impressed with the sound quality of the Airpods.
