It has the gaming vibes design with glowing razer logo since mobile gaming it a big trend now. The slim control center located on the right side, it house the charging port, microphone, volume rocker and call/media playback functions. The button are clicky but it requires some force to actuate them. The microphone is near to the mouth area and has good vocal pick.

What’s unique about the wireless headphones is the battery hub doubles as a Magnetic Clip that can be snap on to the shirt so the cable doesn’t dangle around, we tested this and it is as good as the shortening cable tabs from other brand. This is a good approach from Razer as most of the battery weight is located behind, rather on the earbuds or control center. An innovation from Razer and this works well for sporting and gym activities.

The sound isolation is good thanks to the long sound tube in combination with double flange eartips, I wished it was angled as well for better comfort fit. The Razer Hammerhead BT is powered by pair of 10mm Neodymium Dynamic Drivers. It uses Bluetooth 4.1 for connectivity and supports Qualcomm aptX for android devices. The maximum stable line of sight is 12 meters.

The rated battery life is 8 hours. Our battery test is based on the iPhone 6 at the 2nd volume bar. Yes it is that loud, usually for other brand we need to set the volume around 3rd to 5th volume bar. Our test result gave us a total of 11 hours and 40 minutes.

AUDIO QUALITY

Audio Quality test performed on the Iphone 6.

POP/EDM:

Tiaan – Be Ok (Low bass frequency)
The low bass frequency is superbly energetic, you can feel the air pressure booming in your ears. It doesn’t eat into the vocals and has zero bass distortion. The subtle bass vibration fades smoothly. Low bass frequency is well bodied. The low bass doesn’t overpower the vocals much and both sounds balance.

Pia Mia – Do It Again (Standard bass)
The bass is superbly energetic, you can feel the air pressure. The bass fades ultra-butter-smoothly especially at the 2:05 mark, the vibrations is just an eargasm. The bass doesn’t overpower the vocals, it feel balanced and there is a clear separation between the two. The bass is well bodied. EDM tones sound fun.

Vocals/Instrumentals :
Violinder – Raindrops (Instrumental)
The piano/violin tone sounds right and natural, it leans closer to the crystal-clear type not the warm-sound. Personally, I prefer crystal-clear type. It has right amount of shine at the highs, just spot on. The tones are well bodied it doesn’t sound half-hearted. The bass/drums feels balance with piano/violin in term of audible levels, tho there is clear separation between the two. Good indication of a balanced IEM.

Pentatonix – See Through (Group vocal / Hi pitch vocal)
Mitch Grassi’s hi-pitched-male Tenor vocals perform very well at the highs with the right amount of shine, it feels bright. Each singer can be identified easily. Every diction and pronunciation is crystal clear. Vocal beatboxing, echoing and humming is eargasm which doesn’t overpower Mitch Grassi’s vocal in the song.

FINAL VERDICT

I’m rather surprised despite this model being gaming oriented wireless headphones which should be heavy on bass and bad mid frequency like all the other gaming headset/headphones in the market, but NO! This IEM performs well for the low bass frequency right up the the high frequency. I’m shocked as Razer improve so much from the first gen cabled version.
