InEarMonitors are, like any speaker purchase, a deeply personal choice that will factor a range of preferences over a list of preferences the next person may favour.
I have learned comfort is key with regards to headwear/headfi…
It is hard to coax me out of some Ultrasone Edition 5 (over ears, “very comfortable”)…
but when I do, some bluetooth sennheiser ‘buds’ often get the duty… (IE80BT) mostly due to being bluetooth/apt x and used for phone calls…
for music listening, the best bargain I have found in recent years are some Astell and Kern ZERO1 IEMs.
If a pundit looks into the Zero1’s they will quickly learn that AandK had a few cooalaborations in the IEM market with a couple of companies famous for ‘multidriver’ In Ears.
They even write it into the blurb on the side of the products box’ - they basically liften the Research and Development from some of the best on the planet, and then derived their own ‘perfect’ InEarMonitor.
The Zero1 have a Planar tweeter, two balanced armatures for the midrange frequencies, and a dynamic driver for low down ‘bounce’…
The replacement Zero2 double the price point and also the tricky amplifier loading’ I’d say the Zero1 are the perfect IEM whose only caveat is - like being played ‘soft’.
At low volume, the lack of distortion and their cohesive sound (again; stole the R and D from some of the best!) make them a great ‘reference’ sound.
Their failing is in the distortion that kicks in with a moderate volume level…
if a user doesn’t seek out an in ear for super loud listening, these should be a short list contender.
I auditioned against some ‘massive multi driver’ designs and found their timing (of frequencies) to be an issue, and a mess to listen to.
The Zero1, for their relatively low price point (vs competing products), are what I consider a true bargain, and as an avid headfi pundit myself; amazed at how these slipped under the radar…
they deserve amplification much higher in price point than they will typically be paired with, and scale up beautifully with better equipment.
I’d say they sold for half their true value (or less), and now, on sale, are a real steal for getting ‘a lot of bang/to buck’ as a ratio.
Their included mmcx cable is decent as well, equivalent to the couple of hundred price point silver hybrids by ALO…
black Zero1 come with 4.4mm balanced cable,
silver Zero1 come with a 3.5mm cable…
Sure the price point IS higher than a lot of budget stuff,… but these seriously flogged flagship parts from a few of the high end and ‘better’ IEM makers.
(seriously Astell and Kern liften years of research and design from several of the best IEM makers and launched with these IEMs at ‘too cheap a pricepoint’)
Bargains (in a first world hobby perspective)
