Sound quality is a subjective opinion tho (i mean sure, technically you can measure it, but most people are just going to go off of how it sounds to them, personally). If i wanted something that was more robust id probably spend more and get bigger head phones and not in ear joints. I wouldnt be in the 150-200 range.
But I feel they sound fine for what i want them for (working out, talking on the phone, casual music listening), I am not an audiophile tho
.
I don't feel "convenience" is gay because of the bolded. They work as advertised with apple products. I have an Iphone and an apple tv and they all work seemlessly so the 150 is worth it to me. Not saying i wouldnt enjoy other headphones just saying I enjoy what apple brought to the table and dont think 150 was too much for it. Other ppl would probably want higher sound quality and thats fine, im no audio phile so the sound is decent IMO.
