You'll love it.

It sounds like you have already decided on the S350, so my post is a little redundant, but I just thought I'd say that I was making exactly the same decision a few months ago and I went with the S350. I haven't once regretted the choice. The extra voices were a big factor for me, but also the multi-track recording and the ability to plug in an audio source and play along. I use the latter feature more than I thought that I would and it's lots of fun.

For anyone experiencing similar issues or generally wondering about a good, fairly modestly priced set of headphones for use with the S350, I'm glad to say that the Sennheiser HD 206 are fine. The volume is much better than the HD 400s and the general sound quality is a close match for the speakers.

Thanks. I might well do that if the HD 206 doesn't work out.

Thanks. The HD 206 are already ordered, so I'll have to go with those for now, but I'll definitely keep your tip in mind. I hadn't heard of "impedance matching". As you can probably tell, this is not an area that I have any expertise in. These are the specifications for the Casio CDP S350 phones/output jack: Stereo mini jack - 3.5mm Output impedance - 3 Ohm Output Voltage - 1.3V (RMS) MAX My Sony headphones (which were too quiet) have nominal impedance of 24 Ohm, but so do the HD 201, which were much louder. The 400s (also too quiet) have a nominal impedance of 18 Ohm. As green as I am about this stuff, I thought that the Sound pressure level (SPL) was going to have a bearing on volume. It's 120dB for the HD 400s, 108dB for the HD 201 and 98dB for the Sony. By that reckoning, the 400s would be the loudest, so that reckoning was clearly wrong. I'll have to read up more about impedance matching.

Thanks. I have indeed found that different headphones produce different results. My initial concerns were when using a cheap pair of Sony headphones. The output just wasn't cutting it. As I said before, I don't want a ridiculous volume, but I do want enough so that I feel immersed in the music. I found that a pair of Sennheiser HD 201 headphones produced a much better sound, but they are broken (one phone snapped off), so I decided to replace them with a pair of Sennheiser HD 400s. That was an upgrade, albeit still relatively cheap by Sennheiser standards. To my surprise, the 400s were significantly quieter than the 201 and I didn't much like the general sound either. I've sent those back and gone for the Sennheiser HD 206 (the new version of the 201) and just hope that the 206 will be near identical to the 201. I might pull my hair out otherwise.

Hi. I purchased the CDP S350 a few days ago and I'm very pleased with it. The only slight blip for me is that the headphone volume does seem rather quieter than expected. Even on full volume, it's really not very loud at all, particularly on some voices. I don't want to be blasting out music at a silly volume or damaging my ears obviously, but just a little more volume would be nice. Has anyone else had the same experience on this or another keyboard? If so, I'm wondering if there's an easy and preferably fairly cheap solution. Perhaps something to boost the signal to the headphones? Thanks.
