Yet another noise sufferer on the verge of a Falling Down-esque meltdown here! I also live in a flat - I think that flat dwellers should be the target market - and have had my sanity compromised by constant drilling and hammering coming from the flat below which is being refurbished. To my delight, not only did these little beauties arrive the day after I ordered them, they work an absolute treat! Don't be fooled by their soft, squishy appearance, as once placed in the ear, they expand beautifully and block out any hellish din. Sanity intact. Excellent stuff!
