Hi   I think it is true that there are differences in quality of reproduction between very cheap amplifiers and DACs and ones that you pay a bit more for, however the very expensive amplifiers and DACs probably offer nothing over the more sensibly priced ones.   Mass production has meant...

Hi KaBAKZ   I have used my AKG K702 headphones for a few years now and I absolutely love them. These are truly great headphones.   I will now comment on the issues you have raised.   Amplification   Well I haven't heard the "magni/modi" that you have so I have no idea about that.   My...

I really like my AKG K 550 which seem to fulfil the criteria in the original post well.   I would question the desire for "warm" sounding headphones. Obviously "warm" can mean many things however personally I find any audio equipment that warms up the sound to be really unattractive after a...

  I have K 702s and the Sennheiser HD 540 Reference Golds. Earlier I wrote I had the K 701s however my K 702s are the K 701s with a detachable cables and very dark blue in colour.   The sound of the Sennheiser HD 540 Ref Golds is certainly very different indeed from the K 702s. I don't think...

  Well, I have the AKG K701 and a pair of Sennheiser HD540 Reference Gold headphones. I bought my HD540 headphones new in 1991 and the K701s I bought a couple of years ago.   The easy answer from me to your question is that there are no similarities imho between these two headphones.   The...

 

  I agree that audio is a well understood science and that our perception of sound is not well understood.   The human hearing did not develop to test out audio products, it developed to assist with the survival of the human species.   While human hearing is extremely sensitive it is...

  Well I do agree with you. The AKG K550 headphones give you terrific sound quality and isolation. There are better sounding headphones of course, but it is hard to find headphones that offer this combination of sound quality and isolation. I have never found the K550s to be bass light, however...

The coolest circum-aural headphones I have are my AKG K702 headphones. These are of pretty much the same design as the K701, Q701 and several other models.   I do think that supra-aural headphones can be suited to hotter weather. I like my B & W P5 headphones in very hot weather, I have used...

  Hi   Thank you for telling me about your experiences with these headphones.   I find the AKG K845BT to be of interest because I really like my AKG K550 headphones and the AKG K845BT looks to be of a similar design.   The first priority is signal strength because of the particular use I...

  Mac users?

  Have you any experience of the signal strength of these headphones?

I think that usually "Burn In" is more in the mind of the user than it is in the equipment.   If I were you I would just use the RS180 headphones as normal. If they improve in some way over time then they will do so with normal use.

  Thank you tinyman392 for this suggestion. I am checking out the Harman Kardan BT headphones now. I see that in the UK they are £219 which is do-able for me. Also I could get them from Amazon which would let me have 30 days of trial.   My Sandstrom headphones have come back to life since I...

For some time I've been using a pair of Sandstrom SBTHP11X bluetooth headphones with my MacBook Pro. The sound quality from these is basic but I use them when watching TV programmes and doing a bit of housework at the same time. They are fine for dialogue. The headphones have died all of a...
