HiFiGo Kefine Delci Sinngle 10mm Dynamic Driver in-Ear Monitors, 1DD DLC + PU Diaphgram IEMs in-Ear Earphones with Powerful Bass (3.5mm)

I am an IEM aficionado, and I own every type of IEM, from budget picks to pairs worth whole paychecks. These Kefine Delci IEMs are truly amazing. Despite their price, they sound like pairs I own worth several hundred dollars.Why? Because of their remarkable balance of tuning and technical ability. They are detailed and crisp and natural sounding, like a great speaker system. They are so, so natural and listenable, and deep and full and exciting. Wow.The accessories are amazing. In the box you get a great quality copper cable, and a zip case that is just perfect, in addition to ear tips. The build quality is summit-level: made of one piece of aluminum, with a classy grey finish.This is my favorite single dynamic-driver IEM. It would make a great gift for someone, to get them hooked on audio, or as an affordable hi-fi treat to those who want great sound without breaking the bank. The Delci is so, so good.

For under $100 these are amazing. I have many IEM’s ranging from Sennheiser, to KZ to Celest and Letshuoer, and more. Out of the box, I prefer the Delci. Good emphasis on sub bass while retaining upper mids and treble. They are warm sounding, but not lacking in a bit of sparkle when called for. Extremely comfortable to wear. Good selection of tips and a cable that I don’t have to look to replace soon. A very good cable. The case is a big plus too.

I am somewhat of an amatuer IEM audiophile in training. These IEMs come with a pretty nice cable, a decent build quality, and all in a small package. They tend to fit nicely in the ear but I did not have great luck with the ear tips that came with them. The cable is high quality but a little stiff around the ear. I did easily chip the paint in a tiny spot, but I dropped them. These are easily one of the best value proposition in IEM.Nice pillow bass that extends rather deeply, not a treble lovers IEM, but nothing is veiled or too cut off. So it strikes a nice balance for those that are treble sensitive. This is a nice all around set that leans on the side of consumer earphones rather than overly detailed niche in ear monitors.

I really wanted to give a great review since I totally love the sound, great definition and perfect fit at least for me. Among all the items I currently have this is the set that fits me the best and there are some of my favorite songs where the sound was amazing, I have a great selection of iems ranging from $20 dollars to $100 and $240and I'm not going to say that this set is the very best ever but fit is important and for $60 dollars that I paid I believe was an excellent choice but sadly today 40 plus days the left side has lost power and I can hardly hear it! Otherwise this was an easy 5 star set, I have use my PC, my phone and my portable music player and there is no improvement and this is the very first time I'm experiencing this kind of trouble with iems, I have by KC which started me on the rabbit hole of this hobby, a set that I bought I think 5 years ago and they sound like the very first day I got them so I don't understand what happened with KEFINE! I love the shells and the small design, the cable is great and the sound was so good but I can't even return them! So if anybody is interested on Kefine Delci you will love the sound but hopefully you will get a better set than me!

When I got in to this hobby I promised myself I would not spend more than $100.00 on an IEM, cost to performance, I do not believe would you get that much greater at $100 plus at my age. LOLFirst these are good at giving some good Bass, and a kick in the sub bass, I do feel like that bleeds in to the mids a bit. For me this is the worst part of these IEM's. I kick up the Mids around 1k or 2k just a pinch to compensate, or you could just lower the bass a bit if you want to.The Mids are good and clean, the best part is the upper mids are held back just a bit. I am a little sensitive to the upper mids around 4k and these do not cause any fatigue.The highs give some sparkle and air without ever getting to harsh. A nice smoothness to the highs.The case is nice and useful, the cable is OK, not great but not bad. The tips I can not comment on, as I never use or even try the included tips. I find they feel like any normal included tips, so best of luck on this.As a whole, I am very impressed by these, as I mentioned some good bass, clean mids and controlled highs. They have a nice musical sound, the detail is there but these are not the best for critical listening. These are perfect for laying back and relaxing, from Mozart to Metal, Hip Hop to Jazz, etc.... works on these. From my collection these easily fall into my top 3 now. This is my first ever 5 star rating on an IEM, one they are that close but I will not cut them short, as most would appreciate the extra bass. By no means are these Basshead IEM's as a note.

This really is a quality IEM. The sound is warm, detailed, good bass extension, with great male and female vocals. There is zero sibilance to female voices on the high end. The treble is smooth but not bright or forward. Physically, it’s a solid feeling all metal IEM with an excellent stock cable, a rarity at this price range. It punches well above its price range, and should be a shortlisted IEM on your list to buy from. I seriously recommend it if you’re not looking for a very forward treble. I’ve used it across multiple genres, and yet to be disappointed.

These are awesome for the price. They do great in Rap, RnB and EDM out the box. They don't sound terrible on other genres, especially compared to most wireless. Good as is out of the box, but can be even be better for more detailed nuance with parametric EQ.

I really do not like to leave a bad review because I think these iems are some of the best sounding and most comfortable at this price point. I primarily used them for PC gaming at 20% volume. These are the best I've used for gaming even compared to my seinnheiser ie600s which were 6 times the price.Unfortunately, I've had three of the right side iems fail since purchasing the first set in April '24.Messaged the seller a week ago about the third failure and haven't heard a response.
