J&R offers the Sennheiser CX 870 Earphones, model no. Cx870, for $32.99 with free shipping. That’s tied with our mention from two weeks ago as the lowest total price we could now find by $19. (We saw them for $3 less on Black Friday.) These headphones feature a 17Hz to 22.5kHz frequency response, ear adapter set, diaphragm guards, cleaning tool, and more.
