Let me first say that I received the P180 Edifier earbuds after I agreed to provide a review of one of the Edifier earphones; and I would like to thank Edifier for giving me the opportunity to review these new earbuds. I did not request to receive the P180s specifically, and I am not sure how the company randomized delivery to volunteer reviewers. I do have to admit that I am not a huge fan of earbuds; historically, I have not liked the fit, the lack of isolation and the absence of some detail in the music when I have compared them to my IEMs. However, I will do the best I can to review these earbuds, while comparing them to 2 other earbuds (Philips and Hisoundaudio PAA-1) I have in my collection. One of our Head fi.org colleagues, Bloody Penguin, is an admitted fan of earbuds and has also reviewed the P180 earbuds, so please read his review to get his perspective.
The P180s arrived in a nice package with a user's guide, a pair of foam earpads, and a cable adapter. The P180s have a microphone/remote that is compatible with iPhones and most Android phones. I have tested the mic/remote with my iPhone and I can say it functions well.

The build of the P180s is fairly standard for earbuds in this price range. In fact, the shells for the P180s are exactly the same as the shells for the Philips earbuds (DIY) I received as a freebie from Dasetn. I must say that the cable for the P180s is nicer than the cables on the Philips earbuds. The cable of the P180s has a supple, rubbery texture, similar to the cable on the Hisoundaudio PAA-1s; whereas the cable on the Philips earbuds has a stiff, cheaper plastic feel. In my opinion, the plug for the P180s is more attractive than the plug for either the Philips or PAA-1.

The specifications for the P180 and PAA-1 are somewhat similar:
P180: Driver 16 mm; Impedance 32 ohms; Sensitivity 100 dB; Frequency response, 20Hz-20KHz; cable length 130 cm; connector 3.5 mm stereo
PAA-1: Driver 16 mm; Impedance 32 ohms; Sensitivity105 dB; Frequency response 20Hz-21KHz; cable length 119 cm (but unequal cable lengths for R and L sides); connector 3.5 mm stereo
(I am unable to find the exact specs for the Philips earbuds). The P180s have a mic/remote that can be used with iPhones and most Android phones, neither the PAA-1 nor the Philips has a mic/remote.
The sound quality of all the earbuds depends on whether you use them with the foam earpads or not. The earpads tend to increase the bass and take some of the treble away from all 3 earbuds. I used the earbuds on my Xuelin iHiFi 800, which has a fairly neutral sound signature. I tested them all with a variety of songs by artists such as A Perfect Circle, Puscifer, Adele, Jeff Beck and Aynsley Lister. I personally prefer using the earbuds with the foam pads, because I can get a better, more comfortable fit this way. Under these circumstances, I found that the PAA-1 had too much bass, with incomplete separation between bass and mids. The bass had a tendency to overwhelm the vocals and the highs were muddied. In comparison, both the P180s and Philips earbuds fared better with the foam pads. There was much better separation of bass from mids, and treble was better preserved. I enjoyed the PAA-1 sound quality more when the foam pads were removed, but I had a hard time getting a good, comfortable fit. With further comparison between the P180s and the Philips earbuds, I found that the P180s provided more natural sounding vocals, and bass and mids came across as more "powerful" in the P180s. In comparison, the overall sound of the Philips was a bit more recessed. The P180s had a similar sound stage to the PAA-1s, and both had broader sound stages than the Philips earbuds. Even though I am still not a huge fan of earbuds, I do feel that the overall sound quality of the P180s (based on my preferences) is better than the sound quality of the PAA-1 or the Philips. In fact, the detail and clarity that I get with the P180s (compared to the other 2 earbuds) come closer to what I experience with IEMs, and this is a big plus for me. To be honest, I don't know how much I will use these earbuds in the future due to my preference for IEMs, but my 16 year old son has already asked me if he could have them... so, one way or another, I think the P180s will experience extensive play time in our family... Although the P180s are a bit generic in their appearance, the cable that Edifier has used is a step up and the sound quality is quite good; at their price point, I feel they deserve 4 stars. (For comparison, I would rate the PAA-1s 3.5 stars and the Philips 3 stars).
In terms of cost, searching Amazon tonite (11/24/15) I found the Hisoundaudio PAA-1 earbuds for ~$14 (US) and the Edifier P180 earbuds for ~$17. I was unable to find an exact match of the Philips earbuds on Amazon, and it appears the Dasetn website is no longer active.
Finally, I want to thank Edifier again for the opportunity to review the P180s and wish them the best of luck with their business.
