Not the easiest fix, but I think everyone must get a set

I’ll get straight to it: if you’ve been following my quest to jump aboardSennheiser’s trial custom ear tip scheme(which involved a wild trip toHigh End Munichtoget my auricles 3D mapped inside and out) and have been wondering whether it was all worth it, I have the answer, in three words: yes, yes… yes!
And I’m not just quotingWhen Harry Met Sallybecause it turns out that my asking for “Chelsea blue with my name etched on, please” during said appointment in Germany resulted in a set of tips that could, according to various sources, be mistaken for Viagra pills in low light. No, no. They’re justthat good.
Simply put, these little blue lozenges make some of thebest wired earbudsI’ve ever worn even better. Arguably my favorite wired earbuds at the moment are the superlativeCampfire Audio Solaris Stellar Horizon, and it’s those levels of detail, clarity, agility and insight I’m now getting from some much cheaper Sennheisers. And it’s all thanks to the company’s unique Sennheiser-specific ear tip pilot scheme.
The IEMs I’m using are the Sennheiser IE 600, aka the in-ear monitors that sit just below the firm’s flagship IE 900 proposition, but Sennheiser’s Custom Comfort Tip trial scheme earpieces will work on the company’s IE 200,Sennheiser IE 300, IE 600 orSennheiser IE 900audiophile-grade, TechRadar-recommended wired earbuds.
As you’d expect, the ear tips have a little red dot on them to denote the right tip, which corresponds with the thin red halo on the driver housing of my IE 600s. I cast aside my trusty Comply memory foam small ear tips and quickly pop the Custom Comfort Tips over the nozzle. Easy.
Once they’re mounted on their respective units, a lovely little representation of what Sennheiser’s audiologists called my “really short” ear canals on both sides is revealed. Other visual cues suggested by my colleagues at this point include, “I think someone stuck chewing gum on your earbuds”, “Is that the end of a chewed Bic pen?” and my personal favorite: “Ah, you accidentally dipped them in sealing wax when sending one of your letters.”
The audiophile in me simply shakes these jibes off. I’ve patiently waited a month for my excellent little ear bits to arrive – and nobody will even see them once they’re in my shell-likes anyway. Also, because these are wired earbuds, there’s no moulded battery nest for my kit to no longer fit into.

And that leads me to another reason everybody should get these Custom Comfort Tips if Sennheiser does the decent thing and rolls the trial out globally: wired earbuds differ from thebest wireless earbudsin many ways. Honestly,hi-res audiois just the tip of the iceberg. You see, despite my beloved wires offering better security as well as superior analog audio quality, they do present a challenge. You won’t lose one earbud to a puddle in the way you can with a wire-free design, but no matter how snag-resistant the cables, and how easily the ear-hooks snake around your biological listening gear, youwillpull one on a button or sleeve at some point. And if your earpieces don’t fit properly, they might fall out.
Physical drop-outs happen often with my old EarPods (a cheap option, but one Istill think beats any of Apple’s AirPods), but they certainly don’t occur with my new pricier Sennheiser setup and my Custom Comfort Tips. Far from it in fact – it’s worth noting that you’ll need to take a moment to carefully extract them from your ears after a listening session.
Sennheiser’s best, but better
Having researchedAvery’s solution to fix my AirPods' poor fit, I’ve triedUE’s excellent heat-to-fit earbuds proposition(called theUE Dropsif you’re looking for a true wireless option) and my search forthe best earbuds for small earsis an ongoing battle that’s currently being won bySony’s beautiful bijouLinkBuds S.
But nothing I’ve tried to date has equalled this level of security, comfort and audio fidelity. It stands to reason that achieving a near-perfect seal betwixt the external hardware and your own skin and cartilage will level up the talents of your headphones, and yet it’s still quite special when you hear it for yourself.

The driving beat in Sam Smith’s Barbiecore dance romp,Man I Am,feels like it grazes the underside of my brain before chimes greet my left ear and Smith’s vocal bursts through the middle. Better than with just the regular Comply memory foam tips then? Across the board.
How do you sign up for your own set? It’s not that easy, only because it remains unclear whether Sennheiser plans on making the trial scheme a global affair – and how much it might cost. I will reach out to Sennheiser and let you know of any updates. Until then, you’ll find me with my IE 600s hooked up to mySony Xperia 1 IV, seeing what this simple audiophile system can do withQobuz’s best new hi-res playlists. I call it my happy place – I hope you also find yours this weekend.
