necrotoxico Posted April 11, 2005 Report Share Posted April 11, 2005 (edited) Im thinking on use a technics RP-F300 is there a problem on using a huge earphones like this on a mdlike execive power drain or something?thats allthanks and salutes againPd:a huge sorry for posting this on general hi-mda newbie here Edited April 11, 2005 by necrotoxico Quote Link to comment Share on other sites More sharing options...
dex Otaku Posted April 12, 2005 Report Share Posted April 12, 2005 Larger headphones tend to be lower in impedance and sensitivity. Larger drivers generally require more power.This doesn't mean that all headphones are impractical for MD / HiMD use, though. I have a pair of 16ohm Sennheiser HD330s [c.1995] and straight from my NH700 [only 5mW/channel] most music becomes ear-splittingly loud at only 22/30 volume. If you're serious about using your portable for full-sized headphone listening, I'd recommend using a dedicated heaphone amp [at home, at least]. The headphone amps in some older MD models are much higher in power than current models, too. Your manual will say what the rated power output of its amp is.If you don't have a manual, there's a section with downloadable PDFs for many models on minidisc.org .Having to use higher volume levels [read: higher power] will affect battery life, but this will depend on the efficiency of your 'phones [sPL at a certain power level]. It doesn't hurt to try it. It might be really quiet, in whch case you obviously need a headphone amp. Quote Link to comment Share on other sites More sharing options...
bhangraman Posted April 12, 2005 Report Share Posted April 12, 2005 I go by the maxim: "Amplifying mediocrity with mediocre amps becomes louder mediocrity with added distortion." And where possible, I do like to go unamped. It's possible to use big headphones with the limited power of Sony's built-in amps, especially as newer amps seem to be back to the 90's when a 5mw rating was a lot more powerful than the truly pitiful "5mw" players of up to a few years ago.But, you have to select carefully based on impedance and SPL ratings. With Sony amps, the former should be low and the latter should be high. For example, the Sony Qualia 010 that I use semi-portably has a SPL of 100db/mw and an impedance of 70 ohms. It works out of the (non-European) portables, but there are times when I frequently feel that the phones are wanting more power. (which is why I don't use the 010 with Sony gear... it's a shame) In the case of the RP-F300, I'm seeing figures of 102db/mw (usable, but not perfect for direct MD use) with 22 ohm impedance (good). So what you'll get is something quite usable for the most part, but there might be some instances where you might feel that the phones are being underpowered. Provided you keep the volume low, it shouldn't be a huge problem. Quote Link to comment Share on other sites More sharing options...
robin726 Posted April 13, 2005 Report Share Posted April 13, 2005 Larger headphones tend to be lower in impedance and sensitivity. ←Do you mean higher in impedance?To repeat or at least reword...For any situation in which you don't have a dedicated headphone amp you want headphones with low impedance so that they are easier to drive by the suboptimal amp that comes built-in to the portable device. It doesn't matter how physically big the headphones are, though you might start bumping up against people in the subway if they are too big. Like these: Other factors, like closed vs. open vs. in-ear have more bearing on what you might want to use. I use Grado R225 at home, even from my tiny MP3 player. In this case the 1/4" plug plus 1/8" adaptor is about the same size as the player, which looks funny but sounds great. (The DAP is an MPIO, which has outstanding sound.)

The Low Volta Posted April 17, 2005 Report Share Posted April 17, 2005 I'd turn the question on it's head and say why listen to a portable at home?←ah, 'cause "at home" is a relative expression (at least in my case):I (officially) live with my parents in Hasselt (Belgium), occasionally I stay at my girlfriend's parents (Beringen/Belgium, but actually all cities I'm going to mention are in Belgium ), I study in Brussels and I've lived and studied in Ghent for six years and still have/visit a lot of friends over there and finally my girlfriend has a house in Antwerp which isn't completely finished yet, but we already camp out there from time to time...add to this that I have well over 400 cd's...and you see why it's easier for me to put 'em on MD, and just carry my little machine, a number of md's and my big 'phones around for a nice audio-experience (I could use the line-out and let everyone enjoy the sound, but my girlfriend doesn't really agree on my music taste )just to show that context can determine meaning: my 'home' = 'portable' Quote Link to comment Share on other sites More sharing options...
necrotoxico Posted April 19, 2005 Author Report Share Posted April 19, 2005 salutes to allfinally Im a happy owner of technics RP-F300 phones usd $40 aprox.range 10 Hz a 27 KHz Sen 102 dB/mW Imp 22 ohmsmax in power 1.000 mW40 milímeters magnet3 meters cableextra bass (XBS) 190 grams Conector mini plug (diámeter) 3,5 mm. plug adapter (diámeter) 6,3 mm. magnet Ferritathe good: -powerful bass-great sound-gold connectors-it covers the full ear and isolates ext sound very well and people around you cant ear a thing of what you are listening-tested on mz nh700 and the sound level can go beyond a very insoportable level way long. so the md player can feed the phones very wellthe bad:too long cablehuge hearphones(people look at me too much on the street) Quote Link to comment Share on other sites More sharing options...
