Having had a wonderful impression of the current state of Bluetooth-powered sound with the Brainwavz BLU-100, I felt it was time to take a look at something a bit higher-end. Fast-forward about a couple weeks later, and here I am with the Sport-Fi X7. Will these $80 Bluetooth IEMs catch up to the competition, or will they get left biting the dust? Read on and find out!

I'm the proud owner of the AKG K240, first-gen Beats Studio, Beyerdynamic DT770 Pro, HiFiMAN HE-300, JVC HA-MR77XE, JVC HA-SZ2000, Koss PortaPro, Philips Fidelio X2, Sennheiser HD650, Sennheiser HD800, Xiaomi Pistons V2, Xiaomi Pistons V3, the MrSpeakers Mad Dog 3.2, and now, the MrSpeakers Alpha Dog.

In 2014, I went to Canjam Europe. Mr. Speakers was there, showing off his Alpha Dog. I tried it, and didn't like it at all. A long time passed before someone I know sent me an e-mail a few days ago and let me know that he was going to sell his Alpha Dogs for 450 euros (They're 600 euros around here). As I am a huge Mr Speakers Fan, I just went with it and I'm very happy I did, as these might be my new favorite headphones.

On to the real review now.
