Ellie J. ★★★★★

Even with the display unit label, the headphone kit was in solid working order and only had a tiny scuff I barely notice.

Victoria J. ★★★★★

Was pleasantly surprised by how clean the soldering points were on this display unit — the kit's components are well-organized and everything fits together snugly. Had a minor scuff on the headband but for the price it's a fantastic way to build your own cans.

Chloe X. ★★★★★

Came here for a budget stereo setup and the kit had everything I needed for the assembly—no missing screws or clips. The display unit has a couple of tiny scuffs but nothing that affects the sound or fit.
