I had three weeks to spend with five ‘ChiFi’ IEM’s, the Kiwi Ears Orchestra Lite (which I already own, so didn’t listen), Hidizs MP145, Yanyin Canon II, FiiO FH15, and 7hz Legato. Thanks to the awesome
@Damz87 for organising
I have many ChiFi IEM's myself, with all the Kiwi Ears except the original Orchestra, along with a few non ChiFi TOTL, and many midfi IEMs. Listening was done primarily through iPhone -> FiiO Q7 -> IEM using Tidal. I like everything and anything when it comes to music.
My experience with the lower end of the market is that they generally excel at one particular genre, midfi is more allrounder, then TOTL goes for allrounder or back to one particular genre. Let's see how these go.
Kiwi Ears Orchestra Lite: I've had these for a while, they're exceptionally detailed for their price however they lack a cohesive sound so I don't find them overly enjoyable for just sitting down and relaxing. If I want to really hear a particular instrument in a track, or for gaming, I find these to be pretty good. Given my large collection these are not in rotation at all for my general listening, however they are sat next to my PS5 and do get used there whenever I'm not using a gaming headset. Not recommended for music, recommended for gaming.
7hz Legato: My review can be found
here. In summary I found them to be very much a one trick bass pony. They are not the IEM for me, and I don’t think they’d be the IEM for most people. If you have some IEM’s already, and are after something bassy and not too expensive, maybe. They don't get a recommendation from me. They did excel with guitars for my ears, along with bass focussed tracks, however I found them quite intolerable for pretty much anything else.
FiiO FH15: I was looking forward to trying this out, I hadn't read anything however I've enjoyed some of the cheaper FiiO IEM's and thought they may do well with a more premium one. I was wrong. It's a 3BA, 1DD hybrid, nicely built, didn't come with it's full kit (so only the red filter was included), however from looking at graphs it doesn't appear to make a massive difference. Sound wise I found it to be below average, there is a focus on bass which leads to a muddy overall sound however once you’ve had them in your ears for a bit you get used to it, but it’s extremely obvious moving from a more balanced IEM to this one. There is an overall dampening to the sound which reminds me of what happens to my ears when I’ve been at a concert and my ears are starting to give up. Not completely horrible but not what I could recommend at the price point. I'm sure they weren't going for burnt out ears sound but once I figured out what it reminded me of the absolutely nailed it. I didn't find them particularly good with anything,
Hidizs MP145: 14.5mm planer IEM, comes with three different nozzles and three different tips. Should be enough to find something that you like, all up I do have a preference (rose gold nozzle and balanced tips) however this only got me to an acceptable sound. They don't do anything wrong but also don't do anything particularly amazing. I've since ended up with a free pair from a friend as the nozzles didn't work with his ears (they are quite big) and I give them an occasional listen. If you're after a mid priced planar they're not a bad option, but I think you can do better at this price point and would recommend Hidizs's own MS3 over the MP145. They're very neutral for a planar and excel with tracks where you want to hear detail (similar to the Kiwi Ears Orchestra Lite however they overall sound better for music than the Kiwi Ears). Vocals are decent and detailed.
Yanyin Canon II: I'd never heard on Yanyin before this. Had no idea what the price point was. I put these in after listening to the Legato and the FH15 and it was like coming home. Beautiful, musical, effortless sound. It's not an extremely detailed IEM, it's more akin to something like the 7th Acoustics Supernova, where you just pop it in your ears and get lost in the music. They were easily my favourite from the ChiFi tour, and I ended up buying a set. The packaging they come in is quite nice, you get a little leather case, and they also have some tuning switches. Both switches increase the bass (and only the bass), with my preference being Up Down, or both Up. I landed on Up Down as my preference. I found them to work with all music, and punching well above their price point. They're in my normal rotation now and have been getting a lot of ear time since they arrived. Highly recommended.
All up it was interesting to hear all of these side by side, Legato and FH15 do something different to the norm (and don't succeed for my ears, but I'm sure it works for some individuals, Legato I could almost own just for how it does guitar music), Kiwi Ears Orchestra Lite works great for gaming but find them very lacking for most music, MP145 plays it extremely safe and I guess succeeds at that but I find it overall a little boring, and the Canon II was an amazing find for a musical IEM which I believe punches somewhere around double its price. The Canon II is the only one out of the five that I'd give a strong recommendation to, if you're after a cheaper IEM have a real good read of real users impressions (not so much reviews as a lot of them just hype everything up), or buy something like the Kiwi Ears Cadenza which is a great starting point and then figure out what you'd like more / less of.
