Ok so it is 2017 and I'm late to the party but I just got this headphone from Singapore Jaben because it seems they were clearing their stock. I got this for a whooping $34.90 SGD!! When I looked at the price I knew I had to get one for myself!!
Anyways moving on the review, I'll try to be as detailed and easy to understand as I can, sooo bear with me on this
 
 
Build Quality: Everything is made of plastic. The headband is plastic, the earcups are all plastic. Except for the open-back portion of the headphone. its made of metal. But however because its all plastic, it is EXTREMELY light. Also the headphones are not built extremely solid and tight. When I twist the headphones, they make a squeaky sound sooo I suggest to treat it nicely if you were to buy one.
 
Comfort: These headphones have velour earpads and headband rest so it is rather comfortable. Clamping force is slightly tight but because it is around ear style it doesn't bother me that much. You will always feel that is one your head, it doesn't disappear from your head due to the clamping force. But after hours of use, it might get uncomfortable just because of the clamping force.
 
Bass: Bass is really enjoyable. Bass extends quite deep and it is has adequate amounts of it. In my opinion it's a perfect amount of above average deep bass that doesn't mix with other frequencies of the song. Mid bass is tight and doesn't cover the high hats of my songs when they are clashed together. The Bass is correct in almost all aspects of a headphone IMO.
 
Mids/Vocals: The vocals are just amazing! This is first time I realized that on different songs, the vocals are positioned differently. Sometimes the singers are forward and at times in the center. Vocals are clear, you can hear each nuance of their voice. Voices don't have any signs of sibilance even when played at loud volumes. 
 
Highs: Now comes the tricky/weird part of this headphone that makes it (unique?) or lacking compared to others. I feel it is averagely extended which is why it doesn't give the airy soundstage. But the soundstage is still likable to most consumers I believe. It's as if they are playing in a studio sized room.(A middle balance between airy and congested). Moving on to the weird part, high hats sound crisp and not overwhelming. However coming to strumming guitars and piano, they don't sound crisp especially guitars. The strumming of the strings just don't have that "ting" sensation. Also high hats and everything else same as the vocals, dont have any sibilance. However they sound slightly bright, just slightly. That alone explains how smooth the highs are with the roll off rate being very likable.
 
Overall: The sound leans towards more of a balanced signature. IMO it really is a good strike of balance between lows, mid and highs. The DR150 has done it right. It literally will suit any genre you throw at it. A more detailed impression between the balanced signature would be that vocals are louder than the bass and highs. To me the bass and highs are really almost the same loudness. 
 
Summary: So what do you get when you buy this headphone? In short, a VERY enjoyable balanced sound signature with no sibilance, a chunky 3m detachable cable and below average construction. What you really get for when buying this is just for its sound and really nothing else. For the price of 34.90 SGD,it is hands down one of the best in the sub 50 range. However at 100 USD, I feel it is just as good as its' other competitors but there will definitely be a better package then the DR150.(Especially due to the construction) For 100USD I would give it 4 stars. However for the price I paid for, definite 5 star.
 
Thanks for reading this review and if you found it helpful, I'm glad that I have helped you in some way or another

This is my first ever review on Head-Fi and I felt that I just had to write a review about how awesome these earphones are. I will be sharing my views about the sound quality and the comparison with other iems that I have heard.
 
So for the sound quality...
 
Lows/Bass:
The bass is deep, Very deep, although you won't be expecting a SUPER strong mid bass punch. I feel the mid bass punch is significant enough but Bassheads looking for that SUPER mid bass punch MIGHT not like it but it depends on your preference. This earphone like mentioned is more for sub bass pleasure. 
 
Mids/Vocals:
The vocals aren't too far away neither too near, it has a good distance to it. The vocals are relatively smooth but has enough energy to engage the user. I like it alot.
 
Highs/Treble:
Treble is pretty good in my opinion. I like the treble to not be too overly extended making it non fatiguing and that's what this iem does. The presence is there, it's crisp and the clarity is pretty good compared to the iems I have. 
 
 
 
Now comes the comparison of different iems I have tried:
Sennheiser Momentum in ear: The sony xb90ex has better sub bass but the mid bass between the 2 are about the same. If i were to find an exact difference, I would say the xb90ex has a tighter bass while the sennheiser's has a fuller impactful bass. Mids on the xb90ex are definitely better in clarity, positioning distance (due to recessed mids on the senns), and engagement. However lastly, the treble extension on the senns are much better than the xb90ex, the senns have more crisp and detail. OVERALL SOUND: The xb90ex overall sounds much clearer while the senns sounds abit thick as if the sound is going through a layer of wall. This could be because of the upper bass making sound chesty.
 
Rock Zircon: I dont really know why people dont compare these 2 earphones together as they are both considered basshead earphones. To me, the rock zircon has a stronger mid bass and a stronger sub bass, In fact the rock zircon are so bass heavy you can literally feel/hear the thumping bass of the songs.I am confident to say that the rock zircon is one of the MOST BASS HEAVY EARPHONE EVER. (Like legit not kidding) These are what you call true basshead earphones with good treble extension and stable mids for its price range. I would choose this over maybe audio techs cks solid bass series or senns cx3.0.( BUT please always give a demo of them before buying!)

And now I have come to the end of this review. I hope that my first review has helped anyone in making a better decision of buying earphones but also remember to trust your ears before buying rashly!
