where dyuh get those in-ear moulded ear -plug/ speaker thingys?
There are audiologists around who do them, most companies who offer custom eartips will have a map which will show your nearest based on postcode, my nearest is in Trowbridge, for example, although some opticians offer the service for hearing aids; mine were done through an independent optician in Bath, but they no longer exist.
They do make an enormous difference, though; mine are on a pair of Etymotic ER6i 'phones, which I bought through a load of recommendations on here. I was very
disappointed with them, even after forking out nearly £100 for the eartips, because they're very light in the bass. I gave up using them, instead got a variety of UE phones from eBay, SuperFi 3 and 5, and TripleFi 10, and the Shure 215's.
All of them are vastly improved by using triple-flange eartips, a cheap alternative to customs, but not quite as comfortable.
I've recently gone back to using the Ety's, having found an app that allows a custom equalisation curve to be created, which puts back the missing bass, making a really big difference.
No remote is a hassle, but if you're a clever bugger, it's possible to replace the wires with those from Apple earbuds, but it's a bit of a faff.
I still use my UE's and Shures, though. The Shure triple-flange eartips will deform with extended use, shaping themselves to your inner ear, putting a small amount of Sugru behind each flange, then putting them into your ear would make a cheap custom eartip; here's mine, showing how they change shape:
Here's my Shure 215's along with my Etymotics, it's obvious why there's less bass with the Ety's,
