Why would I turn the charging ability off? The unit plays music fine with it off or on?** A: 1) you need to switch it on to charge the unit. 2) you can set it to off to prevent it drains battery of your phone when you connect it (via usb-c not bluetooth) to your phone. 3) the unit plays music fine regardless of this switch's setting. hope it helps. **Q: For those on ios (iphone or ipad), are you able to save your 3 custom eq settings on to btr7 from fiio control? heard there was a bug.** A: This is bad advice. The app is extremely easy to use and the parametric equalizer is perhaps the best feature and the reason I purchased this amp. I use iOS and saving the settings is easy and practically automatic. The custom EQ is only adjustable through the app. I’m not sure why so many people have problems using it. It seems so simple to me. My only issue is when you reset the custom EQ to default (flat), it resets all 3 at once. It would be better if you could individually reset each one. **Q: Can this be charged while in use?** A: Sure can. This little amp is amazing! **Q: Will this product increase the frequency range of my headphones? currently 20-40,000 khz, will this get it down to 10khz and improve dynamics qualiy** A: Your headphones' current range is 20hz to 40,000 Hz or 20hz to 40 kHz. It is already past 10 kHz, and will not reduce it. What this device will do is improve sound quality with less background noise, or hiss and so more dynamic range. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Among the Best Portables Out There *by on Reviewed in the United States November 15, 2022* I bought the Fiio BTR7 after seeing some glowing reviews of it on AudioScienceReview.com (ASR), an audio hardware review site that uses a fancy audio analyzer to assess how well DACs and other other audio equipment reproduce sound signals.ASR concluded that the BTR7 is on par with desktop-class DACs and amplifiers in its ability to reproduce music.The sound quality of Fiio's products have always been outstanding, and the BTR7 takes it up another notch. The BTR7's signature is clean, smooth, and satisfying, with no emphasized frequency ranges or audible distortion. The BTR7 uses a two quality ESS DAC chips, a quality clock source, and two THX-certified amplifier chips to produce an exceptionally clean signal, especially for a portable device.I mainly use the BTR7 as a plug-in DAC for my MacBook, but its sound in Bluetooth mode is also exceptional. It supports any Bluetooth codec you can throw at it; I mainly use AAC (as an Apple user), but if your phone supports LDAC or AptX, it can decode and amplify those too.The power output is outstanding. The BTR7 can easily power my Sennheiser HD6XX headphones, at a whopping 300 ohms. I can even power my insensitive HifiMan Sundaras with the unbalanced output, though the balanced 4.4 mm output can drive them even better. The BTR7 will drive any headphone you have with no problem, and turning up the volume won't lead to distortion.The only downside of this product is the software. Not only are the menus on the device hard to navigate, but the companion app, Fiio Control, contains many extraneous features and lacks a user-friendly user interface. For example, the equalizer function is incredibly hard to understand, as it doesn't label the individual frequency bands, so you have to guess what frequencies you're equalizing based on the shape of the frequency curve.Overall, the BTR7 is the best portable DAC/amp on the market right now. If you want a powerful Bluetooth amplifier that will drive your full-sized headphones, or simply want a portable external DAC/amp for a laptop, this is a great solution. I'm impressed with what Fiio has accomplished in building such a compact, well-engineered product at an affordable price. I highly recommend the BTR7, and I'm very happy with my purchase. ### ⭐⭐⭐⭐⭐ Outstanding! *by on Reviewed in the United States July 1, 2023* I've got to say that I am really impressed with this tiny little marvel! It just sounds outstanding! I have owned and enjoyed a Fiio E10-K for several years but it had been serving as a back-up option until recently, when my Audioquest Dragonfly Cobalt disintegrated. It was the second and last of the dongle DAC devices I will ever own. While that one sounded terrific the build quality is absolutely terrible and what happens is that the headphone jack breaks free and falls inside of the casing, leaving it inoperable. Audioquest replaced the first one under warranty but when the second one did the same thing they didn't even respond to my email. It was no longer under warranty I assumed but at least they could have responded to me. It's OK, I just won't support this company any more and have been turning many of my cohorts and fellow audio enthusiast away from their overpriced, fragile products. My cobalt was never abused in any way, it is just not well made.I decided to upgrade my E10K and chose the BTR7 because of the excellent reviews and the respect for the product shown throughout an online audio group of which I participate. This group is over 40,000 strong and there are some real knowledgeable people in it with vast experience with these products. After receiving my new "toy" I had some learning to do as this Fiio isn't exactly plug and play. It took me a little while to figure out how to navigate the tiny buttons and the process itself. I struggled to get it to pair up with my laptop, not because it was terribly difficult, but because I didn't realize that I needed to have the BTR7 connected via the usb-c cable to my laptop at the time I was trying to get it to pair. It wasn't like pairing my phone or my Mark Levinson 5909 headphones. When I realized the err of my ways I felt incredibly dense! Once paired I was ready to have a listen.At this point I have to admit that I have just a few hours of listening time on the BTR7. I have listened to both the 5909 wired, where it really excels, as well as my Sennheiser HD660S2, a wired headphone. The 5909 is an easy to drive headphone but the 660S2 is not at 300 ohms, yet the BTR7 can drive it to plenty loud volume levels with authority. It is absolutely dead silent when no music is present, silent during quiet passages, too. To my ears this tiny piece of kit sounds every bit as good as the $350 Cobalt, and it was just $200. It's far and away better built. If there is anything at all to report on the negative side it would have to be the software. That menu system kind of sucks. But I think once configured it shouldn't be an issue. I managed to figure it out on my own so I can't imagine others not being able to do the same. I can highly recommend the Fiio BTR7 to everybody. I have already started doing so! An excellent choice either out and about or simply away from the desk. ### ⭐⭐⭐⭐ Works great *by on Reviewed in the United States June 26, 2025* I have a previous version of this and this one is slightly larger than the old one. It also has had some connection issues but that might be because its trying to connect to multiple devices because it previously connected to them. IE it drops connection to my phone from time to time and then comes back. Not entirely sure why its been doing that recently. Overall enjoy it. Sound quality is great and convivence is also great. Battery life is a little worse than the older model but that's because this one is bigger and has a color screen. ## Frequently Bought Together - FiiO BTR7 Headphone Amp Bluetooth Receiver High Resolution Portable DAC Supports MQA/LDAC/aptX HD 384K/32Bit DSD256 for Phone/PC/Car/Home Audio - Sennheiser HD 600 - Audiophile Hi-Res Open Back Dynamic Headphone - Youkamoo 4.4mm Balanced Replacement Upgrade Cable Compatible for Sennheiser HD650, HD600, HD660S, HD660S2, HD580, HD58X, Massdrop HD6XX Headphones Upgrade Cable --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/458570626-fiio-btr7-headphone-amp-bluetooth-receiver-high-resolution-portable-dac](https://www.desertcart.fi/products/458570626-fiio-btr7-headphone-amp-bluetooth-receiver-high-resolution-portable-dac) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-06-21*
