Bio
So wouldn’t consider myself as a serious audiophile otherwise I would be bankrupt by now! But I do like my sound to remain true to the quality of what the artist intended and would invest a little bit more for the benefit accurate, decent and appealing sound.I have some experience of IEMs ranging from lower tier muddy mids and bulging bass CX400 and Sony EX500 to Middle tier HifiMAN RE-0, RE-262 and high tier Westone UM3x
As well as giving a review of the RE-272 themselves I’ll be comparing them to the aforementioned with exception to lower tier.
Brief sound signature of RE-0 / RE-262 / Westone UM3x
RE-0 The poster child of bang for buck – clean and very detailed highs, cymbals and crashes are nicely textured. Bass light, mids are slightly recessed but these can be completely forgiven as these punch well above their weight given the quality of the high end. Easily driven straight from a portable.
RE-262 Effortless mid-range. Silky-smooth response with vocals and acoustic material. Highs are a little muted but does present a little high-end sparkle at times. Soundstage is truly amazing for an IEM design - almost bordering on full size can territory. The overall signature is warm but not dark with mid emphasis. Can be driven from a portable but really needs a head amp to make them sing.
Westone UM3x These share a similar characteristic to the RE-262 namely a very smooth mid-range presentation. The UM3x has a narrower soundstage but this can be overlooked given the pin sharp rendition of instrument separation. Endless bass extension but yet balanced as not to sound inherently dark.

RE-272 Review
Presentation
The presentation box is identical to the RE-262. The jewellery box adds to the drama of opening a flagship product.
We have the usual selection of HifiMan tips, 2x ML dual flange, 3x SML mono. The dual flange work best for me, however I’m using the softer mono Sony Hybrids tips, the dual flange give better bass extension but create a slightly hollow midrange.
As this is the flagship product it would be nice to see HifiMan include a small hard carry case like Shure/Westone. I much rather the RE-272 retail package be nicely designed cardboard packaging to offset the cost of the jewellery box versus a small carry case bit this is just nitpicking!
Quality
Initially I’ve had a few issues/replacements with my first HifiMan product the RE-0. However after each replacement Hifiman used better quality materials, down to the thickness/texture of the cable, sturdier Y splitter and more forgiving cable relief on the ear buds. The quality is great and the RE-272 is no exception; the built quality is a culmination of all these incremental improvements. The gunmetal metallic coating also gives it a premium feel.

Sound
Initially the RE-272 had very harsh highs straight out of the box. I did initially try to listen through the harshness but this is a dynamic driver I thought it would be best to put in a few hours of burn in time. So after 36hrs the mid’s were more apparent and the lows slightly more extended (with the right tips/seal). Giving the RE-272 detailed but more rounded signature.
Lows If your looking for a dark headphone you might need to look elsewhere.
The RE-272 were initially bass light but after a few hours of burn in the low end started to show itself. The bass is well measured and accurate but not earth shattering. It could benefit with a little more extension.
Mids The RE-272 retains some of the qualities of the RE-262 with a small warm-mid bass characteristic. Vocals are very forward, and with material such acoustic guitar the RE-272 reveal a lot of texture. The mid soundstage is a little narrower than the RE-262 but what you lose with a wide slightly coloured soundstage - you gain with better imaging and Highs.
Highs This is where the RE-272 excels. The Highs are immaculately detailed and forward. The RE-272 signature is more closely aligned to the RE0’s with highs that have a very fast decay and are wonderfully textured. You can almost hear every brush on the cymbals.
RE-0 vs RE-272 Initially, before burn in I thought these were exactly the same IEMs! After a few hours of burn in the RE272 began to show its colours. It was apparent that the RE-0 has a slight V shaped signature with mids slightly veiled. Whereas the RE-272 rendition of mids and vocals outclass the RE-0. The highs on both IEMs are incredibly crisp with the RE-272 edging out, as there is slightly less resonance at the high end.
RE-262 vs RE-272 Despite looking exactly the same but with a lick of metallic paint they are completely different animals. When listening to the RE-262 I really appreciate the smooth delivery of the mids but I was always wanted a little more extension on the highs. The RE-272 addresses the RE-262 shortcomings but with its own character. The mids are still very present in the RE-272 but now with forward highs and better separation of instruments.
RE-272 vs Westone UM3x The UM3x inherently sound warmer down to the endless bass extension but do not manage to sound dark as this is kept in check with the other balanced armatures. The RE-272 sound comparatively flat but manage to hold their own with the highs. I would go as far to say that the high’s on the RE-272 are more detailed, crisp and better than those of the UM3x. The UM3x posses a smoother midrange and incredible instrument separation. Both IEM’s soundstages are similar and relatively narrow.
Conclusion
What we have here is an evolutionary step from HiFiMan. The RE-272 addresses the sonic characteristics of the RE-262 recessed high and presents us with some of the cleanest highs but yet keeping that all important midrange (albeit less smoother) presence the RE-262 is renowned for.
The RE-262 was a big departure from HifiMan’s ‘house’ sound being conservatively flat but incredibly detailed. The RE-262 was relatively warm with a bias towards mid bass. The RE-272 on the other hand shows us what HiFiMan are incredibly good at imaging and detail at the high end of the spectrum.
How I would generally characterise the RE-272 would be if someone mashed up the RE-0 and the RE-262 and we have the RE-272. Of course there is much more than this. The RE-272 high end should be a benchmark in the IEM world; it’s nice to hear the RE-272 is capable at times of producing some pleasing low notes.
If you’re looking for a relatively neutral sounding IEM with incredible detail the RE-272 are for you.
It will be interesting to see the next flagship HiFiMan IEM. Will it still be another accomplished dynamic driver or will it be an armature driver's'. Whatever it might be . . . please HiFiMan - be brave a little more extension with the bass next time
