If you're on a budget and need versatile earbuds for a mix of activities including some casual listening and TV, the KZ ZSN Pro X might suit you, particularly if you need something portable with a fair noise isolation for commuting. However, they have limited features, with no wireless option and poor mic quality that is not ideal for calls. On the other hand, if you want the highest sound quality and the best listening experience for music and have the budget for it, the Sennheiser HD800S would be your pick; they provide an exceptional soundstage and comfort but are open-back which means poor noise isolation and they aren't suitable for exercise or noisy environments. Remember, the Sennheisers are also much bulkier, not great for travel, and need an amplifier to perform best, adding to the cost. Give Feedback

"The KZ ZSN PRO X offers superb sound for very little money, like under $30 USD. It has some rough edges with a plastic seam on the cable that can rub on your ear, and the bud is a bit large. The tech isn't cutting edge, but new doesn't always equal better. You should try it."
