RHA CL750: Precision HiFi Noise Isolating in-Ear Headphones for Amps & DACs

I'm not a professional sound engineer who could evaluate its distinctive sound quality, but just a music lover who wants to hear any types of music at its raw quality w/o major distortion/enhancement. I have humble collections of headphones (AKG K141 MkII, Grado SR80e, Nuraphone, Nuraloop, and several earbuds/earphones) to cover my broad music tastes (from Heavy Metal/Rocks to Jazz, Classic, or just sound of nature). I was looking for a headset which could deliver the most natural sound as possible w/o hurting my piggy bank (what an impossible goal). Without fully understanding what high impedance means in the acoustic world, I took my baby step buying RHA CL750 as a starter. I was originally looking for wireless earbuds/headphones for mobility, but I felt economically the wired ones could give more benefits over the wireless counterparts. For me, the true enjoyment of listening music would be sitting at the comfy chair and listening my favorites. A lot of reviews suggested this requires a good amp or DAP, which I didn't own, in order to experience its full capacity. I just hooked this into my cell phone (Galaxy Active S8), set the volume at just above the mid range (60%), and played a music. I've noticed its outputs were little weaker than my other headphones, but I could tell it would be much crisp and clearer than others (more torward the natural sound). I could hear subtle noise like guitar chord switch sound, accidental rimshot, or inhale sound from vocals). Noise isolation is awesome with its eartips (12 pairs provided, including 3 pairs of Comply tips, various sizes/styles) and it is very comfortable to wear for a long time (ear hook wire seems very well designed - just gently sit on your top ear). If you are looking for heavy bass, this might not be the one for you. If you like classics or vocals, this might be the best one for you. I even liked the sound of heavy metals (or heavier ones) thru RHA CL750. Well, hearing is very subjective. This would be my personal music and sound preference. Hope this might help someone for their buying decision - which headphones/earphones would be better for you. Enjoy!!!

Build and sound quality is good, and Noise isolation is also good.

I love them! Major upgrade from the RHA S500 that I love. The build quality is what I have come to expect from RHA, top notch. These are not light in the hand but when in the ear they feel great. The cable is the best I have felt on an IEM, nice length, soft and light but yet durable. Though I do wish that they had included a 1/4" adapter. The cable is not removable but that isn't a deal breaker for me. As for the sound, these have a "V" signature, the bass and treble are more forward than the mids. The mids aren't recessed very far though, they don't sound distant. I actually love the mids, they have nice texture and are where I prefer them. The bass is extended and goes deep when called upon but it isn't overly impactful. The treble is where these will be a love or hate IEM. For me the treble is glorious, high, bright with a smoothness that just makes it all sound detailed and clear. They remind me a lot of what you get from a set of Grado or BeyerDynamics. If you are treble sensitive or love thumping bass, these are not for you. But if you like a sound that has great detail in the bass and treble with smooth mids, give these a try. Make sure that you have a powerful amplifier to push these, your normal DAP or cellphone will not make these sound full of life.

These are amp/dac necessary devices. I’m no audiophile at all, but these sound and feel great! I wear them for pretty much 6 hours every day, pulling them in and out of my ears. They come with a bunch of different tips to suit your style. Hard to hear outside noise with some tips vs others. Braided cord rarely every tangles. Only thing that tangles are the shapes that curve around the ears. But much less of a hassle than normal ear buds. These are super sturdy metal housings and the craftsmanship feels amazing. If I lost these somehow, I would definitely be buying a replacement pair immediately! Quality earbuds!

Great headphones, definitely need an amp to push them. I recommend burning them in, they sound better the longer I use them. Good quality build. This is the second pair of RHA’s I have owned the other being the T10’s. Have not been disappointed with either.

I use my LGV30 for playing High Res and Flac files. They sound terrific. Plugged them into my Bluetooth connected amp and they just don't get along. The High Impedance mode is triggered from the phone but there is barely any volume compared to lower impedance IEMs I have. The sound quality is solid for right out of the box. Will test them out some when I have time but if I have to purchase yet another amp I'm going to be giving up on this hobby and just stay with my Periodic Element BE's - just a great all-around performer alone or amped.

From my first impressions the headphones are very good and with the large variety of tips everyone can find a pair that will work for them.Would recommend.
