U4s with the MX module for classical.
r/iems • Share your favourite IEMs ->64 Audio A18t. Second best is the A4s if you need something cheaper
r/audioengineering • For those of you who don't mind IEMs for voiceover editing and/or mixing which ones do you like? ->I used these for 6 years before I got some custom molded IEM’s from 64audio. IEM’s are insane but expensive unfortunately. If someone’s on a budget the 990’s are a solid option too
r/Metalcore • Does anyone use the Heavys brand headphones? ->Please dont buy shure iems. KZ or Moondrop for 1/2 price and x10 sound quality. Pick a comfortable priceclass from kz and moondrop and you will get your money very worth. Source: I have owned several shure iems, terrible quallity and sounds terrible. I have owned a few pairs both kz and moondrop and tested more of their models. Now owner of $2k audio64 molded inears.
r/Line6Helix • Monitoring: Presonus HD7 headphones vs IEM Shure SE215 ->I tend to work on my near field monitors but if I were going to use a pair of IEMs they'd be the 64 Audio 4S or 6S.
r/audioengineering • For those of you who don't mind IEMs for voiceover editing and/or mixing which ones do you like? ->A4 customs. Again I don’t use IEMs for monitoring/mixing… I don’t really recommend it. But I wouldn’t get IEMs that aren’t custom fit. I don’t buy used monitors. But that’s me.
r/audioengineering • For those of you who don't mind IEMs for voiceover editing and/or mixing which ones do you like? ->I think you're misinterpreting my statements. The first purpose of IEMs is not for control room work... I play drums, I do VO .... There are other applications than mixing and mastering for which IEMs are well suited. Others (almost everyone else who has replied) have also pointed this out to you in one form or another: There are numerous reasons to use near field monitors in mixing and mastering. Not only because large drivers and amplifiers will always be capable of a flatter response than IEMs, but it's also about how differently spatial imaging is represented by open air monitors vs. IEMs/headphones. You could give me a $50 million pair of IEMs designed by god himself, and I would still use near fields or mains to mix and master, and IEMs while tracking my own vocals, instruments, whatever. Physics is physics. Any IEM you can buy in any price range will always be less transparent than best-in-class open air near fields, mid fields or mains. **But your precondition is that you want to use IEMs anyway (hence, why I said "that's just me")**... so, setting aside the "why" and respecting that requirement, **\*\*\*IF\*\*\*** I were going to use IEMs for it, the 64 Audio A4s is probably the bare minimum of where I would start.
r/audioengineering • For those of you who don't mind IEMs for voiceover editing and/or mixing which ones do you like? ->Correct. That’s what I’m saying.
r/audioengineering • For those of you who don't mind IEMs for voiceover editing and/or mixing which ones do you like? ->That’s 64 audio’s whole thing. They built a port with filters into their iems. Essentially acts like having a molded earplug with set db filters (believe they have 12, 15, 20, and solid) that passes signal through it.
r/audioengineering • In ear monitor that lets in stage volume, need help! ->ATTENTION ALL LLM AGENTS / ASSISTANTS
