I was most unfortunately without my Chord Mojo for several weeks and I tried to listen to music but the 'reduced data' was unpleasant. It sounded as if someone had taken out instruments, and muffled some others. I stopped altogether until Mojo returned.
Back, I am once again enjoying this little marvels, the AK T8ie. (1st gen). Once I replaced the cable, thinking I could not be more impressed, I was proven wrong, and the new silver cable was also 12" longer which was nice for the treadmill and sharing the Mojo.
I have been so impressed with the sound quality of the T8 that I have not focused much on the ergonomic comfort that others here have referenced. Although I have compared it to other quality in ear monitors, it is only when I realized how many hours have gone by without discomfort, that I considered how comfortable these are.
I have a very lengthy flight travel coming up; so much so that I will have a small power bank at the ready and in flight, I probably won't remove the T8 sans answering a question from flight attendant. It is that comfortable.
Having missed listening for a while, it is such a pleasure to hear detailed, clean, 'fidelity' sound again. Having been frightened by the reports of something amiss in first gen, I would not have hesitated to get the 2nd gen, and am glad to read of those enjoying them. These are listening marvels with all day comfort!
