On this graph, blue is active cancellation, green is passive cancellation block out sound by virtue of physically obstructing the path between external sound and your ear drum.
The RP-HC55s actually performed quite well here. The active cancellation blocked out a big chunk of bass noise, which is typically all that active cancellation is good for. It also managed to block out a bit of the mid-to-high sounds as well, which was a nice bonus.
Further, it appears the active cancellation never added more noise than it reduced. We could definitely hear a high-pitched whine when we turned on cancellation in a quiet room, which is why we were a bit surprised to see the blue line didn't dip below the green one towards the high end.
Although that whine might annoy you under ideal listening conditions, we never noticed it when we hit the streets, which is where you're supposed to be wearing these things anway. Our ATH-ANC3 hypothesis has been destroyed: it seems like active cancellation can succeed to some extent in a pair of in-ears. This didn't score as well as a great pair of in-ears, like the SE, so the technology probably could've been obviated for a nice pair of foam plugs.
We test leakage by playing pink noise through the headphones at a set level. We have a microphone stationed a set distance away to pick up on any noise leaking out of the headphone-ear seal. As expected, these headphones weren't the best at controlling leakage. They weren't bad compared to all headphones, but for a set of in-ears they weren't good.
The performance has to do with how active cancellation works. Since it requires a microphone to listen to outside noise, the headphones require tiny holes to be punched in their plastic casing. This lets sound trainsfer in and out of the headphones more easily as evidenced by the poor passive isolation score above. Of course, since you'll feel isolated from your surroundings due to the active cancellation, it's hard to gauge how much sound is leaking out of your headphones.
The first is our typical, 'it's likely your head isn't as horribly misshapen as that of our reviewer, so trust your own judgement over this write-up' spiel. The second pertains to the active noise cancellation pendant. If you're around 5 feet tall, then the pendant will probably reach your front pocket, but we wouldn't count on it.
Otherwise, you'll need to tether the pendant to your shirt somehow. If you don't or can't, then the pendant will flop around and pull on the ear buds. This worked a bit, but the weight from the pendant still pulled on the ear buds, only now the cord rubbed against the garment we were wearing over the headphones.
The combination of this extra friction and gravity's assault on the battery-carrying pendant meant the ear buds would easily pull out of our ears. The best solution is to tether the pendant reduces pulling and then wear something over the cord reduces flopping. If you do this, the RP-HC55s would be an average set of in-ears as far as comfort's concerned.
Other in-ear headphones don't have these crazy issues, not even the ATH-ANC3s, which also have an active cancellation pendant. The earbuds themselves weren't particularly uncomfortable, but the pendant is simply located in an awkward place. Though these weren't the worst headphones we've had to put on, but the restrictions for a comfortable fit certainly hurt the RP-HC55s here. The same issues from above applied here. The headphones themselves didn't get any less comfortable over time, most likely due to the thin sleeves not putting a lot of pressure on our inner ear.
The pendant just creates an awkward situation. The total distance from ear bud to plug, including the control pendant, is 4 feet, 8. This is a bit longer than the average set of in-ears, but not by a great margin. An airplane adapter is also included. These aren't the most well-connected in-ears we've seen, but for they're price they're definitely above average.
In-ears are typically very portable, but the RP-HC55s are a bit of an exception. The control pendant is a bit big, and even though it allows you to snap on a cord wrap to keep your headphones organized, these are going to take up more room in your pocket than the average set of in-ears. While the cord wrap is a nice inclusion, we're not fans of including little pouches as a carrying case. We like somewhat rigid cases with internal pockets, since they both offer protection and optimal organization.
This is only slightly better than just shoving everything in your pocket. There really aren't many ways to customize your RP-HC55 wear experience.
The headphones come with the standard small, medium, and large soft plastic sleeves. There's also an adjustable neck split. Other than these features, however, there aren't many options available. Sometimes in-ears come with more sleeve options, and a few come with a jack split part way down the cable, so you can plug in a volue control or another accessory.
We have yet to review a pair of in-ears that let you disassemble them to any degree. Sure, you can remove the sleeves for easier cleaning, but that's about the extent of it.
There is no cleaning tool included, there's no removeable wax guards, and there's no duplicate sleeves included in case you lose a set.
The RP-HC55s can't play back music when their battery is dead, which is something we wish we'd see less of. A lot of headphones nowadays are making the active cancellation an optional feature, allowing you to use your headphones to listen to music sans cancellation even after its batteries have died. These gripes aside, the headphones have a stupid long battery life, however. One AAA will get you about hours 4.
This is an absurdly long battery life, which is especially nice since you'll need to keep feeding these things AAAs to keep them going.
A 4-pack will last you for almost a month of non-stop cancellation. This single AAA can. The RP-HC55s have negligibly better audio quality and can isolate better, have a ridiculously long battery life, and are quite a bit cheaper.
If isolation and price matter, go for the RP-HC55s. The determining factor in this matchup is your budget and your budget alone. The RP-HC55s actually perform their worst in a quiet environment, because the noise their active cancellation creates will be a bit grating. They don't block out the most sound, but they have great sound quality for a set of in-ears and a tiny little control pendant as well.
Further, they're inexpensive.
