    Not getting really good bass out of these, they do give you loud sound though, I have my calls at minimum volume and these are too loud for me. It's one of the things I really don't like is that they are too loud, they're also kind of big, so I can't wear my normal headphones over them, so I can use my computer and my phone at the same time. But these have lasted much longer than a similar pair I bought before. Decent value I'd say for the price though, maybe even great for people that are hard of hearing. But if you have really good hearing like me, I'd probably try to find something else.

    So these are the first in-ear phones I’ve had. I was convinced closed back phones were the best. I was wrong. Really wrong. My goto phones were Sennheiser HD 280 PRO phones and I only wanted another pair that might be more comfortable to fall asleep in. I was shocked. These have far far more clarity, more bass response, and more comfort. I listen to symphonic works mostly, neutral sound is crucial. They’re not boomy or over trebled. I’ve had them for 2 months, I’m still seriously impressed.

    I was absolutely amazed at the sound clarity and stereo separation. They look much bulkier than the smaller ear buds, but are equal to or more comfortable than most. I use them while cycling, and find that they fit under a helmet well. The sound isolation is better than most ear buds but noticeable wind noise when riding at speed or in winds around 20 mph.
