It has 32 ohm impedance, 40 mm large neo-dynamic drivers and frequency range of 18 Hz to 23,000 Hz . One of the good things about these headphones is that the cable is detachable from the headphones and this will help you whenever you damage the 3.5 mm audio jack or anything happens to your cable. PACKAGING & UNBOXING – On the front of the box you get motorola branding and pulse max picture,On the right side you get list of the box contents and some specifications . Opening the box you get three contents – a headphone, detachable aux cable with in line microphone and warranty and user guide. BUILD QUALITY – Motorola pulse max headphones are lightweight due to its plastic build and they do not feel strong . On the earcups you can see moto logo and as I said earlier they are plastic made . The earcups can rotate 90 degree and I fear that if I use it roughly I might break them at the hinge . The cushioning on the earcups is quite soft and feels comfortable .This has over the ear design but the ear cups are not that big. If anyone has larger ears then it might be a problematic for over the ear use. The headband has leather like soft cushioning and it feels great . One thing you should keep in mind that you will have to handle them with care. So for the build quality I would give 2.5 out of 5 . SOUND QUALITY – It has 32 ohm impedance and frequency range of 18 Hz to 23000 Hz .The mids on this headphones are pretty much accurate , lows and highs struggle and were not upto my expectations. At high volumes audio was not that much clear. The bass is just decent . It is neither powerful boomy like sony xb series nor low . The detachable aux cable has in line microphone for the calls and video chatting. I am impressed with the clarity this microphone has. The sound has very less noise ,For the sound quality I will give 3+ rating out of 5 .
