Below are excerpts from the review:
Although this review is a bit shorter, it is due to the specificity of the product. DD DJ65B is a well-made and very well-priced adapter, it works without any problem and allows you to replace any 4.4mm cable with a large jack, which allows you to significantly increase their functionality and enjoy great sound without any interference. Some might see this as a degradation of such a cable, but there are many great S.E devices on the market, and this is a much cheaper alternative than buying a new cable from scratch.
