I have the Linkbuds S and as much as I prefer wired for quality the convenience of wireless often makes them a more appealing choice. There are times they sound very good but generally the SQ leaves me wanting more so the XM5 sound like a nice step up. My ears small, but I have no issue with my IER-Z1R and the large resin shells of the likes of Oriolus and Unique Melody, I imagine the guide wire may hold assist in a solid fit - I suspect my ears are shallow. For most part the Linkbuds S sit OK and seldom need adjustment, but as they have a second point of contact rather than solely relying on the tip.
I am in Japan and set out to treat myself to a second reasonable tier iem but as prices, even secondhand, are high (even with a favourable exchange rate) I haven't been totally happy with anything to make a purchase. When I first arrived I did very briefly try the XM5 for fit out of curiosity, but was in a hurry to try the wired iems so didn't give it much focus. From memory they were borderline being able to work, but potentially are prone to popping out. I'll demo again for a longer period of time, but sometimes it's not until you walk a mile that you find out if it's going to work for you.
As I'm on holiday my research has been rushed. Back home and here in Japan there are a lot of used ones for sale making me wonder the reason for their selling a highly ranked item.
First of all, I have seen some issues with loss of connection and other functionality, has this been sorted with updates? Are there any specific wireless tips (e earphone has a whole wireless tip section) that help with achieving a solid fit? Is there a hack or mod like a little bit of tape along the back that may provide some grip?
I'd really like to make these work, but if I feel they are going to be a constant daily issue for fit it'll drive me nuts.
