Available in-store at Lidl. As normal it is presumably whilst stocks last. Plenty of black, white and blue available in my store (Oxford).
These in-ear headphones have a shoelace type cable. On the box it says it prevents tangle which I was skeptical about, but I shove the headphones into my pocket and whilst not tangle free they have minimal tangles. Probably more resilient too if, like me, you use them on a pushbike.
The actual earphones are metal rather than plastic like most cheap ones. As you would expect the sound quality won't blow you away but it is loud and acceptable for normal out-and-about listening for me. The earphone have a button and microphone to take phone calls etc.
