Bone Conduction Headphones Effie Wired Headphones with Microphone Stereo Open-Ear Sport Headphone with Noise Reduction Microphone (Black)

Comes from Effie US. The product is Elesound/Bioxar Bone 1(ES-BC900).The actual headset specifications on the box are:~Headphones~- SPL(Sound pressure level) => 94 dB plus/minus 3 dB(Decibels) @ 1 KHz(kilohertz).- MIP(Max input power) => 281 mW(milliwatts) @ 1.5 Vrms(root-mean-square Voltage) and 1 KHz(kilohertz).- RIP(Rated input power) @ 1 KHz => 180 mW(milliwatts) @ 1.2 Vrms(root-mean-square voltage).- Impedance => 6.8 to 9.2 ohms or 8 ohms plus-minus 15% @ 1.0 Vrms(root-mean-square voltage) & 1 KHz(kilohertz)- Frequency Range => 130 Hz(One-hundred thirty hertz) to 15 KHz(Fifteen kilohertz or 15,000 Hertz(Fifteen thousand hertz)).~Microphone~Dimensional: ϕ6 * 5 millimeterFrequency Response: 20 Hertz to 16 KilohertzSensitivity: -54 decibels plus-minus 3 dB.--- Instead of a review, I'll say what I want in the next product ---- Less bass, it is really overpowering.- Wider frequency range. I want more highs.- Even more efficient bone transducers. Higher volume on weaker amplifiers from in-device DACs(digital-to-analog converters).- Maintain sound leakage or reduce it if possible. It is a lot better than the ones with amplifiers.- Ensure a neutral/reference/studio balance for sound dynamics.If possible Elesound should look up Yolie (Audio) from Singapore which is headed by Alex Yu. Do something with them for the next product.

I had bought these for my husband for work but they don’t have very good sound. The bass is ok but the volume and overall sound are not. I say these are ok for a teen or maybe listening to a book but if you like loud and great sounding music, these aren’t the ones.

I was trying to find some wired conduction headphones (no Bluetooth), and these are the best I could find on Amazon. They work well, but I found that I had to turn the volume way up on my device.

Used during my ear surgery recovery. Quality is excellent!

Much anticipated while waiting for shipment from China. What a let down! Worked just so-so in a quiet indoor room. Outdoors it produced only faint and incoherent noise. That’s not even around traffic. Just walking down the street had to forcefully press against each cheekbone to get anything remotely intelligible. All with volume on highest setting. Maybe it’s a poor fit. But I have a hard time believing it isn’t mostly due to the unit itself since it didn’t work well when moved onto multiple locations of cheekbone. Probably not returnable since shipped from China.

Good product

Got this along time ago and dont even know where it is now. I was intrigued by the bone conduction headphones but didnt want to blow off a fortune. However these dont really the the job as well as other do. they produce little sound and are very uncomfortable.

These are good. A little small for my big head, so they fit oddly, but they still work. If I had shorter hair, they would be more comfortable. I have to put them over my hair and put my hair behind my ears to fit them, and they still move a bit, but they work. My ears hurt after a whole of wearing regular earbuds so these are a decent alternative.
