The Alpine Partyplug is a simple two-layer earplug available in four different colors. The filter in the ear is a tube with a hole that the music should ‘filter’. The average noise reduction is 19dB. The party plug comes with a storage case and a tube with which you can easily insert the earplugs into your ear canal. The earplug is made of hypoallergenic material, but your ear can still start to irritate when the tube is blocked by dirt, for example. You will not receive a warranty on the product. The noise reduction deviates considerably on the different frequencies and is not exactly ‘flat’ or ‘linear’, as Alpine calls it. The nominal diameter of the product is 9-12mm depending on how you knead the earplug for use. Shipping costs will be charged on this product.
Alpine Partyplug Pro
The Partyplug Pro is very similar to the Partyplug. It has the same fit and is made of the same material. You have no choice of colors and it comes without a storage case, but with a canister. The big difference is in the filter. An acoustic filter has been installed in the Pro version. You can immediately tell from the noise reduction. This is, in fact, flatter than in the standard Partyplug: the average noise reduction is 21dB. In addition, the Partyplug Pro comes with nice accessorie, such as a neck strap and cleaning spray. Downside of the cleaning spray is that it is not clear whether the earplugs can also be cleaned with tap water. If not, you are dependant on the cleaning spray, which you have to buy separately. If you run out of cleaning spray, shipping costs will still be charged when you restock.
