Has anyone tried the Koss RUK series? (Specifically the RUK30?)

post #1 of 22
Thread Starter 

I did a search and found a post about Koss' release of the RUK line up. However, there wasn't any review available. I was just wondering whether someone had tried the RUK30. If so, I'd be really happy to get any kind of feedback.

 

I am thinking of getting replacement earbuds, and my current options are the Soundmagic PL11 / Sennheiser MX680/5 and maybe the Koss RUK30 if someone puts in a good word for it.

 

Most of the music I listen to would be kind of mellow (jazz, light rock, pop, etc.) If you have other suggestions, I'd be more than glad to hear it.

 

Thanks in advance!

 

(Sorry, now I just realised that it is in the wrong section. I was pretty sure that I clicked on Portables. Unfortunately, I cannot edit this part. Sorry for the hassle. If someone can, please transfer the thread to the correct section of the "Portables." Thanks!)

ruk30 is an excellent product for the price. better than a lot of higher priced earphones from rivals.

 

it is very alike it's brother kdx200. especially in bass performance they are very similar. ruk30 lacks some treble clarity also mids & bass are sounding slightly better together in kdx200 but the difference is very little. one can live with ruk30 if the money comes first.

No. I had the unpleasure of trying 3 pairs of these (one of them came with a broken membrane out of the box and the other one was so unbelivebly flat and had muddy mids that i had to change into another pair and found out all of them are the same) and basically handed off for free to my friend.

sure the bass is excellent, so amazing that i heard details that i never thought i would hear from a bass heavy soundtrack. BUT i am a classical and medieaval/fantasy/baroque lover and the mids on these headphones are rubbish, gut wrenchingly flat and unbearable. Details i love on my music are literally gobbled up by loudness and unnecessary bass and basically no output capabilty. If you are a fan of the kind of music i listen then even a pair of sony mh750's will sound godly next to ruk30.

you can tame the unnecessary bass of yours by lowering the bass amplification from your sound source. ruk30 has a wide acoustic which leads to a good seperation between main frequencies so mids should be clear enough. i don't quite understand what you meant by flat but if you're referring to the frequency balance, you're right. but you can easily EQ it to your liking (and song played). just find an equalizer feature and add 1khz amplification for more forwarded vocals, add 250hz amplification for extra strong bass (like drums etc.), you can try to add 2-4khz, 8-16khz for the mid-high and highs to make related instruments more clear. posibilities are endless. since koss always deliver good acoustic and quality sound reproduction, the rest is up to you. you can also try plug-sparkplug etc. they've different frequency balance, more distant acoustic and more clear treble.

i have spent 3 days burning it in (the last one) and lastly compared the two (mh750 and ruk30) by plugging them in two seperate ipad airs with one earpiece going into one ear each. used the best app available for equalizing (wont advertise here, besides did the tests with one optimus p920 and one z1. same outcome.)

the results are the same. You cannot hear specific mids nearly AT ALL with ruk30. I do not know what or how you are listening it but ruk30 has garbage frequency response to anything but bass. The mids are not there with the same clarity no matter how much finer you tweak it. yes try putting all the mids up on any equalizer, you end up with unnatural garbled inseperable pile of boring **** with it no matter how you tweak it.

Do not buy this if clarity is what you are looking for, id say at 20$ it is the price of its quality. nothing more.

i have had my fair share of editing and equlizing, please i do not need advice.

as i said previously, ruk30 shares the same driver with kdx200 and all of koss products, regardless of the price, represents all kinds ot sounds very well, they've stunning mid dynamics that is very hard to compete. bass & mids in a wide acoustic is something koss never miss. with plug series, you can add highs to it.

I have no knowledge of other Koss series, have not tried them but i definitely know something: an earpiece priced much higher than a low budget earpiece (RUK30) by Koss can never be the same in the hardware part. If what you say is true then Koss is overall garbage which i refuse to believe, i may be new to in-ears but on the over-ear front i have had the pleasure of trying many excellent Koss products.

they're not exactly same, but very similar. kdx200 has more refined treble clarity but lacks a little at extension (duration of treble attack). i prefer ruk30's treble because it's good on extension. their bass production is slightly differs too. but the difference is even low than the treble. kdx200 has more refined 30hz deep bass production. in the means of acoustics, soundstage, bass type & amount, eveything is nearly the same, the differences in total is not bigger than 15% imho and this differences only in some points i stated above.

 

if you compare kdx100 (which belongs to plug series) vs. kdx200 you'll understand why i said ruk30 & kdx200 shares the same driver.

ok so they share the same flavorless unresponsive mids? May be it is just to me like that, but it is good to know they are the same mostly. Mids are everything in the type of music i listen. No crispy clear mids no bueno. Thanks for all your input on the matter, much appreciated.

i really have no idea about what you mean by mids. koss products do not have the distant mid layering of vsonic or havi products. but layers still not close to each other (vertically flat) like in the kc06a or ckm500. so they're just fine and bearable to me.

here is the specific range; ruk30 is subpar of mh750 (that comes with stock z1) between the range 110hz and 10khz. actually spent some hours testing range by range on the same setup i mentioned before. ruk30 is the-in-ears for dumb v shape equalizer lover. enough said.

edit: oh and it is unnecessarily louder by default, more reason to buy for the v shapers. good god.

unnecessarily louder ? do you close your ears when you go to the cinema :) i'm using an amplifier to get even more volume. besides, you can set whatever volume you want. ruk30 has one of the bass performances in this market and probably the best in the price range. same goes for the soundstage & acoustic. it's treble performance is better than a lot of models including 2x priced ckm500 and 3x priced brainwavz s1. the list is expandable...

 

as i said previously again, it comes with the whole range of frequencies unamped (flat). a lot of earphones in the market comes with certain amplifications. koss kdx100 comes with range 60hz-1khz extremely amplified. brainwavz r1 comes with 2khz amplified (weirdly), ckm500 comes 8-16khz amplified (compared to others). stock earphones comes with samsung s3-s4 also the same with ckm500. solution is simple, you can set the level to your liking with the equalizer, again (in the case you don't like it).

 

you can't expect an earphone to suit your needs completely. besides every song already has different needs. so, it's already impossible. that's why we have volume controls, equalizers, amplifiers etc. when you set your levels right, it should be ok because koss earphones has wide soundstage, good bass, moderate quality treble & highs. add that a cheap price.

 

no one says they're the best earphone ever created though. samsung stock earphones i've talked about has better treble for sure. same goes for ostry's. but these are not the only parameters here. ostry is the king of the highs but it lacks on the soundstage and bass side. havi is the king of seperations but it lacks bass, loses agains ostry at highs and very hard to drive. this list is expandable.

 

since ruk30 has wide acoustic, good bass, not bad treble and finally, good price. i'll consider it as a tremendous earphone. if it's coming with flat frequencies which can be correctable by equalizer or it loses at a certain point to a certain models etc. these are just details for me, overall it's one of the hard to beat earphones.

 

i didn't used the model you're referring to, by the way. but i've used a lot of models which the community agrees with their worth. even compared to the most better models i've tried, ruk30 is still accomplishes to impress me, because of the above said reasons. i don't like sony's marketing style and their cheapest products like e818lp or ex50lp sucks... the model you've talking about has fakes everywhere which i suppose the result of the marketing choices (like the xiaomi piston). weird company, weird products. but if it is good on some specific parameter, that's ok for me. no one said it must be bad (i didn't).

you got some very detailed knowledge there and good to read them as one can get great recommendations out of them. Nevertheless i completely agree on the bass front. Hands down best i have heard out of a pair of in ears. Loudness is adjustable yes, may be it is better to have it that way, to clear my point lastly no amount of equalizing saved the ruk30 for me. Now i would really love to hear a rocomendation from you. I am looking for the best in ears which would give me very detailed and distinct mids (for classical music, folk music etc). i HATE overly dominant basses and disturbing treble which ruk30 provides (minus treble) by default. Ruk30 is a total failure for me (even with equlizing).

i'm only interested in budget products and only comparing them to each other so i'm not the one you're looking for. sorry about that.

ok then you must compare the said mh750 (an original one) to ruk30 yourself on some classical sountracks and play around with equalizer. I am sure you will get what i mean. in the meantime i will stick with my stock in ears since they are apperantly better then the budget king ruk30 on what i listen. thanks for your insights.
