Both the P321 and P531 before it have greatly exceeded our expectations. Arctic have managed to bring us decent gaming headsets that should be affordable to all. There aren't really any drawbacks to the P321 – thankfully the minor gripes we had with build quality on the P531 aren't present.
On the whole, we actually prefer the P321 to the P531. It is more comfortable, has a retractable microphone and isn't as bulky. Sure the P531's surround-sound is great but it forces compromise in other areas. Also, the P321 will cost you less.
We had a look around and couldn't find the P321 on sale anywhere yet but the RRP of €32 translates into a shade over £26 at the time of writing. Assuming the price doesn't change before release, this headset is great value for money and we would recommend it to anyone looking for a decent gaming headset.
KitGuru says: Arctic have done it again. Fantastic product at a price that's affordable for all.
