With the RZ-S500W, the manufacturer can justifiably celebrate a successful debut in the field of “True Wireless In-ears with Noise Cancelling”. Market-leading noise cancelling or not – simply put, they work very well and show the more expensive competition that headphones under 180 Euros can also make it to the top of the list. And if you like listening to electronic and modern music genres you will be pleased, because the RZ-S500W’s bass provides cosy warmth and puts in considerable energy. The mid and high frequencies are not as present as the low frequency range, but this can be adjusted using the equalizer if necessary. After all, the RZ-S500W aim to accompany you on all your travels and guarantee you long, fatigue-free listening pleasure – and they certainly achieve that!
