Few years ago, I applied for an online job and had to go through a LOT of learning and training via the web. One of the training sessions required conference chat online with a training manager. We had to put on our headphones for each session so we can clearly listen to the instructions.
Having the right audio equipment is not just for music listening. For online trainings, you would not want to miss every instruction. Quality headphones such as the sennheiser hd595 are a must. Good thing that there was a recorded version after each online session. Anyway, I wasn’t able to complete the training as it required so much of my time and a better project came up.
