It has many applications; it is widely used by audiophiles to help isolate turntables (and neighbours!) from subwoofers and speakers or from the unwanted influences of other equipment and traffic rumble, it is used to quieten the vibration from PCs, hard drives, DVD drives and other spinning equipment, for protecting sensitive scientific equipment, it is even used by NASA to isolate vibration and in the recoil pads of guns. The domed shape of these Fonotek hemispheres further helps isolation by minimising the points of contact. They can be used domed side up or down. They possess their own natural tackiness which clings to most surfaces. If you require a more permanent application, correctly sized 3M peel and stick adhesive transfer circles are also included, these are supplied separately so that you can choose to use them, or not. These Fonotek hemispheres are '50 durometer'; this is the measurement of their hardness or of the amount they 'squish' when loaded and it greatly influences the load rating. This is the mid load rating of most sorbothane products and is the preferred option for most audiophiles and domestic users since it provides the best equilibrium for protection against both high and low frequency influences; other durometer ratings are commonly used for specialised applications including high/low frequencies or temperatures. Sorbothane has a high plasticiser content which gives it a natural 'stickiness'; this is harmless to most surfaces, but can stain some others including varnish, paints and wood; they are supplied with a urethane coating which provides some protection but this can wash or wear off so you may wish use the supplied transfer circles or a small piece of cling-film etc. for further protection. Made in the UK. Review: Very Pleased. - I purchased these in the hope that they would reduce the low frequency hum given out by my UHD player when playing UHD disks. Not only did they reduce it; the sound is now almost completely inaudible. Very Pleased. Review: I thought this item was good but not exceptional - I thought this item was good but not exceptional. Purchased this to know some bass out of my sub-woofer box, but these have reduced the bass too much. ## Features - 4 x Fonotek 30mm Sorbothane Hemispheres - 7.61kg to 15kg per set of four - 30mm diameter, 15mm high.

Not only did they reduce it; the sound is now almost completely inaudible. Very Pleased. ### ⭐⭐⭐ I thought this item was good but not exceptional *by S***E on 28 October 2016* I thought this item was good but not exceptional. Purchased this to know some bass out of my sub-woofer box, but these have reduced the bass too much. ### ⭐⭐⭐⭐ As good as much pricier alternatives *by J***A on 5 April 2017* Using various sizes of these under my turntable, CD and UD players and AVR which, by necessity of space, have to stand right next to one of my floorstanders. But these little hemispheres ensure that absolutely no vibration affects the sound.If you have components with particularly flexible feet installed, you might have a little trouble maintaining balance - my Pro-Ject turntable seems to 'wander' a bit when the pads are placed the ideal way (round side up) but the issue has been solved by inverting the hemispheres, with no noticeable change to the sound quality.I use them on glass shelves but they are quite sticky even when you don't use the supplied adhesive pads, and I suspect they would leave a residue/mark on a wooden surface. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/56669759-sorbothane-hemispheres-isolation-feet-with-adhesive-30mm-4-pack](https://www.desertcart.us/products/56669759-sorbothane-hemispheres-isolation-feet-with-adhesive-30mm-4-pack) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-09*
