Its almost like Vizio forgot to include a chapter. Some may be wondering about the charging and yes, you have to take them off but they easily slide on and off. 00 eachHow about 3pk for $50. In this sense, the DT1990s deliver fully on the promise of the HD600s. I saw some good reviews of these online before I bought them. I have a similar pair and love them so figured he could give these a go. The nubs on the footbed feel a little less prominent than on the regular Crocs, but it doesnt make much difference. As other reviewers have stated this product does not come with the T-Bolt / T-Track style fastener but instead with just standard hex bolts and washers. Also the sound works great 👍 Highly recommended. I have no issue recommending these earbuds to anyone who wants a low priced headset with some really cool features.
