While availing of an upgrade for my phone, there was an option to trade in my old phone, and I've got around $200 for it - unexpected, and of course the logical thing is to spend on an IEM
In the running at the moment are:
- OH10 (due to my love for OH5)
- Kato (as a single DD lover, yet to try this and been curious a while)
- Talos (big fan of DUNU, and intrigued by their execution of a planar set)
Any others I should be considering up to about $200? I'm open on driver config and signature, always curious to explore and generally speaking will suit some shelf of my audio library. One thing is I'm not a fan of large shells, and they absolutely must have vents. I do tend to lean towards single DDs in general.
Regarding your queries:
1) IKKO OH10
- Nice V shaped set with huge bass. Good build and technicalities.
- In this fast moving industry where a few weeks can make an IEM obsolete (looking at you KZ PR1 Pro), and where hypetrains come out like cockroaches every week, if something is talked about just 3 months post release, it is a worthy set to consider. The IKKO OH10 came out 3 years ago and is still recommended and used today, that's how much holding power it has.
- May be a bit fatiguing in the lower treble region, but treble perception may be dependent on hearing health, ear tips, volume played at, pinna gain (ear anatomy), so YMMV.
- The shells are huge and heavy, so maybe best to audition it before purchase.
- I saw the IKKO OH10 at $90ish USD on the BF sales on Aliexpress (after using coupons/coins) and that was a crazy price!
2) Moondrop KATO
- Considered one of the benchmark lower midFI single DDs. Pretty decent technicalities, good timbre. Follows Moondrop's virtual diffuse sound field (VDSF) tuning philosophy (which is their in-house variant of the Harman curve).
- Has tuning nozzles to theoretically change the sound signature, but is a bit gimmicky IMO, the changes are extremely subtle, and other "tunable" IEMs do a more night-or-day difference with their nozzles.
- Some other single DD contenders at the price range beat the Kato in technicalities, eg Tanchjim Oxygen. And considering you own other higher end single DD sets, I am not sure if there is value proposition in you getting this (would be a downgrade). Maybe best to keep your powder dry and save up for a better single DD?
3) DUNU Talos
- The selling point is the switch which can convert it between a pure planar and a hybrid.
- The pure planar setting is pretty good. Balanced U shaped tonality, decent timbre (for a planar) and excellent technicalities. Soundstage is on the smaller side compared to other planars.
- The hybrid switch adds a BA and this setting gives great resolution, sparkle and air, and increases the soundstage. However most consumers will probably find the hybrid setting fatiguing, harsh and sibilant. Maybe it is an option for trebleheads, or niche-case use - eg analysis of music (critical listening), or certain music genres which are darker.
- Most users will probably keep to the pure planar setting, which IMHO is more than decent, good melding of technicalities, timbre and tonality.
