CONCLUSION

   Having already reviewed the GSP 370 i had very high expectations from its larger brother the GSP 670 and i can't say that i was disappointed. Both mids and highs are very clear, positioning audio is surprising accurate and in terms of bass levels well it's actually been a while since i had a wireless headset capable of what the GSP 670 is. Now the GSP 670 does tend to emphasize bass a bit more than the GSP 370 which in turn may "suffocate" highs under certain circumstances but that can actually be a good thing since in both games and movies it produced clearer voice results. Another good thing is the automatic switch between the 2.4GHz and Bluetooth wireless connections since the latter only overrides the former if there's an incoming call (or an outgoing one). The support for AAC, aptX and aptX Low Latency audio codecs was also a pleasant surprise, even though it would really be nice to see a Hi-Res one like LDAC or even aptX HD (granted this would be mostly a marketing move but for some people these audio codecs could actually be the decisive factor). As for battery life EPOS claims that the GSP 670 can last up to 16 hours with 2.4GHz wireless connectivity and 20 hours with Bluetooth wireless connectivity, two numbers which as expected during my tests i was unable to hit. Still i did record just over 14 and 1/2 hours using the 2.4GHz USB dongle and almost 18 hours using Bluetooth so their numbers are not far off (if you decide to use both simultaneously battery levels should deplete even faster). Another surprise was the omni-directional noise cancelling microphone which produced slightly better (clearer and more natural) results compared to that used in the GSP 370 (and that was already a good microphone). Wireless range was also at good levels since i could use the GSP 670 from the next room with a concrete wall in between (roughly 6.5 meters distance) but any farther and problems would arise (something however which applies to like 99% of the headsets out in the market so personally i don't consider that to be a drawback).

   The GSP 670 is the current flagship model in the EPOS Sennheiser gaming product line so it didn't really come as a surprise to see that it currently retails for USD319 inside the USA (Amazon.com) and for 250.58Euros inside the EU (Amazon.de). The only question is whether or not the GSP 670 is worth the hefty premium over the very good GSP 370 and the answer is, it depends. Yes, the GSP 670 is clearly better in every single thing, aside battery life compared to the GSP 370 but audio performance is not worlds apart between these two models so if you can’t afford the former then the latter is also a very good choice. That being said the GSP 670 is not the flagship model of the EPOS gaming line for no reason and since it delivers as advertised it deserves our Platinum Award.
