Denon AH-C751 Earphones

 

Jon takes Denon's latest earphones for a spin and finds that there's a lot to like, but a few niggles too.

The build quality is just as good as the in-box looks - in fact everything about the AH-C751's feels heavy duty. All too often expensive earphones sound good, but come with thin, insubstantial cabling. Those Grado SR325is come to mind, as do Ultimate...

Denon AH-C751 review

 

These in-ear beauties have a surprising amount of bass

Great bass ; Good sound ; Nice design

Lacks some detail ; Bottom heavy sound may not suit all

With a rather bottom-heavy balance, the C751 nevertheless offers plenty of information about familiar recordings – just not quite as much as some

Denon AH-C751 sound-isolating earphones

 

Don't consider them a choice for your workouts, but for seriously impressive sound quality without being full-sized headphones, the AH-C751s are practically unrivalled.

Terrific sound quality ; Booming bass ; Good accessories ; Decent price

Heavy ; Not suitable for use at the gym ; Quite large

If you want a slightly rawer, meatier sound, do consider the SE420s -- with twin drivers in each ear, they're capable of giving you more impact, though you'll sacrifice the absolute crystalline clarity of the C751's treble and bass.

Denon AH-C751

 

While lacking the tonal accuracy and presence of Etymotic's similarly-priced ER-4P, on the flip side, these offer a warmer listen, a potent midrange and lashings of thundering bass. It's very much a matter of taste as to which is preferable, but what's...

Fantastic bass response, stylish, comfortable

Not as well-balanced as similarly-priced models, not a water-tight fit, expensive

Denon AH-C751 sound-isolating earphones

 

These are top level in ears! They sound really really good and the soundstage roomy. Detail separation and bass are great and can be compared with expensive full-size headphones in my opinion (i've owned various full-size cups as AKG K271 S, Sennheiser...

detail separation, bass and mids, design and build quality

highs are bit too bright with some styles of music

Great synergy with iPod touch 2gen, durability on highest level, brings huge fun of listening your favourite music no matter what kind of.

Clarity of lows and highs, Well balanced between detail and melodiousness

Some sybillants in worse masterings

Denon AH-C751 sound-isolating earphones

 

I think that the Denon AH-C751 are a great set of headphones. A touch uncomfortable at first (at least in my ears) however these in ear headphones do a wonderful job of covering the whole audio spectrum. Can't recommend them enough.

Beautiful bass ; Terrific highs ; Great sound overall ; You get what you pay for

It took a while for my ears to adjust to there design, however I'd say this is a common issue with all in ear headphones

Good deep base. Great build quality.

Slightly lost mid range. Very heavy so likely to fall out of ears.
