Sooooo.....my review sample Exo BT (150 USD version) arrived the other day and I've been spending some time with them.
First impressions are positive. Pairing was quick and easy as tends to be the norm for modern Bluetooth gear. Hold the power button until the light flashes red and blue, search for ‘plusSound’ on your player’s available devices list, and select it. Done. I also found that reconnecting to an already paired device is exceptionally quick, a couple seconds max. Much faster than most of the dedicated BT iems I've tried, and the ADVANCED Model 3's Bluetooth module.
Initially I quickly tested three different earphones covering a variety of prices; the budget friendly TinAudio T2 (16 ohms @ 102 dB), the mid-tier Brainwavz B400 (30 ohms
@115 dB), and the premium Campfire Audio Polaris (16.8 ohms @ 97.5 dB). The Exo BT had no issues driving any of them, though the T2 required significantly more juice than the other two to reach the same volume. Sound quality on all three was similar to their wired counterparts. The Polaris didn’t lose out on it’s deep bass and vibrant treble. The B400’s amazingly well-layered and imaged sound stage shone through, and the T2’s neutral character wasn’t lost. Micro-details were smoothed over a touch, but not to the extent I was expecting. Today I spent a good deal of time with the Exo BT matched to the MacaW GT600s (16 ohms @ 98 dB) and they sounded stellar. Some of the warmth was cut which really added to their overall sound (silver/reference filters in place).
Any qualms? Yes, actually. Background static, primarily on the T2. The Polaris suffered from a small amount of static too, but it was easily overshadowed once music was playing. The B400 was nearly silent and along with the noiseless GT600s was my preferred pairing. The initial notification sounds are also painfully loud and need to be turned down…a lot. Thankfully, notification volume can be adjusted with the +/- buttons when music isn’t playing.
Minor issues aside, so far I’m enjoying the Exo BT and I can’t wait to spend more time with it paired to my B400. It feels tough, it looks good, and I haven’t run into any connection issues.
