Product Description

The Denon AH-C350 In-Ear Headphones offer a sound-isolating, canal-type inner ear design. They were created to reduce ambient noise, allowing you to enjoy more of the music content without as much background interference. The newly developed acoustic optimizer provides optimum performance by adjusting the sound pressure balance in front of and behind the diaphragm. Clearer bass and the critical low- to mid-frequency range are more dynamic for today's digital sources.

4.0 out of 5 stars Nice balance of price and performance, March 12, 2008

Just got these to replace a pair of Etymotics Er-6 that died in the left channel. I'd have to say that I like these better. These Denons are a significant jump in sensitivity over the Er-6. I wouldn't recommend the Er-6 for an MP3 player, but the ER-6i might be better according to the specs.

Overall, I'd say the sound presentation of the Denon is similar to the the Er-6 but the Denon has a more realistic bass. Both are nicely balanced from top to bottom. Neither the Denon nor Etymotics have a boomy bass and neither are shrill and showy in the highs. You can listen to either for a long time without fatigue.

I also find the Denon's a bit more comfortable, and not quite as tight. The inclusion of three sizes of ear pads is also a real plus. The Denons also seem to have a bit less isolation and a bit less microphonics.

So this is a nice transition at a very reasonable price. Four stars and not five since they lack the ultimate definition of a top tier set of cans.

4.0 out of 5 stars Big improvement over iPod earbuds for small $$, May 25, 2008

Overall I am very happy - a significant improvement in sound quality over the iPod earbuds, for a very reasonable sum.

I am not such an audiophile that I wanted to spend $[...]+. I wanted something easily portable - so I limited my choices to ear-bud and inner-ear types. From reviews, it seems clear that inner-ear phones provide superior sound quality to buds.

MOST IMPORTANT - QUALITY SOUND
I played my iPod for a while, switching from the iPod buds to the Denons with different songs from jazz to pop to rock & roll. In my opinion:
> the Denons are more sensitive - they play louder at the same volume setting; plus they cut out some ambient noise so you can play at lower settings anyway.
> the treble is a bit strong for my ears, but I think I am sensitive to treble. I found a few EQ settings that sounded great to me though.
> overall the sound is far richer and more detailed, a big improvement.

INNER-EAR TYPE HEADPHONES
If you haven't used this type of headphone before it can take a little getting used to. Like wearing earplugs, while they cut out some ambient noise, you become more aware of your own breathing etc. Make sure you try the different tip sizes to ensure you get the right fit or the sound quality, especially base, will suffer.

CORD
The cord design is quite unique. Clearly the design intends the iPod to be worn on your left side, ideally in a left-hand [...] or handkerchief pocket or perhaps an arm strap. If you wear it there the cord design is perfect. If you don't, there is a cord extension. The extension fits very tightly so there is little chance of it coming loose. I don't find the extension connection is heavy or catches on things.

AMBIENT NOISE
The Denons do not cut out as much ambient noise as some inner-ear models. This was actually something I was looking for as I didn't want to be completely isolated from the outside world.

COMFORT
I played these for 3 hours straight and found they remained comfortable.

At roughly $40, these earphones offer great sound and comfort for a reasonable price. I was not happy with the standard Ipod earbuds but did not want to fork out $80 or more for the Etymotics or other earplug type phones. The Denon's tonal balance is not bright for a change, and some may wish for some more pronounced highs, but I think it is a nice change from the often fatiguing harshness in this area. I am perfectly happy with the bass response using the Ipod's Bass Booster setting--the only EQ setting on the Ipod that does not sound terrible in my opinion. Highly recommended.
