So I think it's about time that Bluedio gets it's own impressions thread. Bluedio started in 2002 by some ex-Beats engineers. They have a good track record of producing solid Bluetooth headphones that provide a lot of bang for the buck. I have noticed that the build quality keeps improving with each new model, and they have come a long way from the cheap all plastic builds of the early models. Bluedio even has a number of models that offer rock solid builds in the form of metal yokes, metal hinges, titanium headbands, etc. Do to this, they are particularly suited to tweens/teens, who are generally extremely hard on electronics (and who usually like the emphasized bass that is Bluedio's house sound). I personally own the following - T3+, T3, T4S, T6, and the TN IEM. I have always been particularly impressed by their battery life, squeezing 3-4xs the battery life of other competitors. The Bluetooth is usually low latency, making most models suitable for watching videos. And I have never had an issue with Bluetooth connectivity - no drops, interference, skipping, etc. I also like the built in microSD functionality of the T3+, allowing music to be played in standalone mode (great for exercising or mowing the lawn). The headphones I own have excellent isolation (again, great for exercising or mowing the lawn). Just keep in mind that the isolation cuts both ways, so in the case of a teen wearing them they will likely be unable to hear you and your parenting requests haha They aren't perfect though. The ear pads on most Turbine models (HT/T2/3/4) are larger than on-ears but smaller than over-ears. This can cause comfort issues and hot spots after a while for some users depending on anatomy. The T5 and T6 introduced larger ear pads, which is a welcome change. Also, the models with metal (T3/4/5/6) are heavy, but this is to be expected because metal is heavier than plastic and it's the trade-off you make with the solid build. Finally, the ear pads are removable but not replaceable (they have integrated clips which makes them incompatible with 3rd party replacements). Which Bluedio models have you tried? What's been your experience?
